Description
TER PRVV0842PE Selector Switch – 2 Position MOM-OFF
The TER PRVV0842PE Selector Switch is a purpose-designed joystick control component for use within compatible TER industrial joystick assemblies. Featuring a two-position MOM-OFF operating configuration, the PRVV0842PE provides a straightforward operator interface for applications requiring a momentary control command combined with a defined OFF position.
Designed for integration with TER Hercules joystick systems, the PRVV0842PE is suitable for Hercules-S and Hercules-CK joystick configurations. It provides machine builders, maintenance personnel and equipment operators with a genuine TER component for maintaining, repairing or configuring compatible industrial joystick controls.
The selector switch is supplied as a wired component and incorporates one contact plus one common connection. Its MOM-OFF operating arrangement makes it particularly useful where a control command should only remain active while the operator deliberately actuates the selector.
As part of a configurable industrial joystick system, the PRVV0842PE can help place an auxiliary machine command within convenient reach of the operator. Rather than requiring every secondary function to be located on a separate control panel, compatible Hercules joystick configurations can incorporate additional control elements directly into the joystick assembly.
Purpose-Built for TER Hercules Joystick Systems
Industrial joysticks frequently perform considerably more than directional machine control. Depending on the equipment configuration, an operator may need to control auxiliary machine functions directly from the joystick handle. Selector switches, push buttons and other handle-mounted actuators allow these additional functions to be incorporated into the primary operator control interface.
The PRVV0842PE is designed as one of these selector options within the TER Hercules joystick platform. Its compact integration allows an additional MOM-OFF command to be incorporated into an appropriate joystick configuration without requiring a separate external selector elsewhere on the operator station.
This approach can help create an organised and intuitive control arrangement by placing frequently required machine functions within convenient reach of the operator. The exact function assigned to the PRVV0842PE will depend on the electrical design and machine control system into which the joystick is incorporated.
Using a selector specifically intended for the compatible joystick platform is also advantageous during servicing. Maintenance personnel can identify the component using its TER reference and compare the existing configuration with the replacement requirement, reducing reliance on appearance alone when identifying a switch.
Two-Position MOM-OFF Operation
A defining characteristic of the PRVV0842PE is its two-position MOM-OFF configuration. MOM refers to momentary operation, while OFF identifies the non-actuated position. This operating arrangement is suited to functions where an electrical command is required only during deliberate operator actuation.
Unlike a maintained selector that remains in its selected operating position, a momentary control is intended for temporary command input. This can be useful in machinery applications where an auxiliary function needs to be initiated, enabled or commanded for a controlled period rather than continuously maintained by the selector itself.
The actual behaviour of the controlled equipment is determined by the wider machine circuit, control logic and system design. The PRVV0842PE provides the operator input and should therefore be selected and integrated according to the requirements of the machine manufacturer and the relevant electrical control system.
This distinction between momentary and maintained operation is particularly important when selecting replacement joystick components. Two selector switches can appear broadly similar while providing substantially different operating behaviour. Checking the complete part number and switch function is therefore essential before installation.
One Contact Plus One Common
TER identifies the PRVV0842PE as incorporating one contact plus one common. This configuration provides the electrical switching arrangement associated with the selector’s MOM-OFF function while maintaining the compact format required for integration into the Hercules joystick system.
When replacing an existing selector switch, it is important to verify the TER part number and existing electrical configuration before installation. Selector switches within the Hercules range are available with different numbers of positions, maintained or momentary functions and contact arrangements, so visually similar components should not automatically be considered electrically interchangeable.
Using the correct PRVV0842PE replacement helps preserve the intended operating behaviour of a joystick originally configured with this particular selector function.
The contact configuration is also an important detail for system integrators specifying a joystick for new machinery. The required operator function, control circuit and input arrangement should be established before selecting the switch configuration so that the joystick component corresponds with the intended electrical design.
Wired Selector Switch for Easier Integration
The PRVV0842PE is supplied as a wired selector switch, making it suitable for integration into compatible joystick assemblies during production, refurbishment or maintenance. For service personnel, having the correct preconfigured TER component can simplify identification and replacement compared with attempting to substitute a generic switching device.
Correct wiring and installation should always be carried out in accordance with the relevant TER documentation, equipment manufacturer’s instructions and applicable electrical safety requirements. Machine power should be appropriately isolated before maintenance or repair work is undertaken.
During replacement, technicians should also confirm the condition and identification of the associated wiring. Existing conductors should not be connected to a replacement component purely on the basis of physical position. The applicable circuit information and component configuration should be verified as part of the maintenance process.
Suitable for Hercules-S and Hercules-CK Joysticks
The TER PRVV0842PE Selector Switch is suitable for compatible Hercules-S and Hercules-CK joystick configurations. These industrial joystick platforms can be configured with a variety of operator controls, allowing the joystick assembly to be adapted to the requirements of different machinery and control applications.
For existing equipment fitted with a PRVV0842PE, sourcing the same TER reference is particularly valuable during maintenance. It allows service personnel to identify the required component by manufacturer part number rather than attempting to match a replacement solely by appearance or general switch function.
This is important because TER offers several selector switch configurations for the Hercules platform. Depending on the required control function, alternatives can incorporate two or three positions, maintained operation, momentary operation, different ON/OFF combinations and different contact arrangements.
The configurable nature of the Hercules system enables machine manufacturers to develop joystick arrangements around the functions required by a particular application. Consequently, two Hercules joysticks used on different machines may not necessarily contain identical auxiliary controls even when their overall appearance is similar.
PRVV0842PE Versus Other Hercules Selector Switches
The PRVV0842PE should not be confused with other TER selector switches used within the Hercules family. The PRVV0840PE, for example, is a two-position maintained ON-OFF selector incorporating one contact plus one common. Although both products use two positions and a similar contact arrangement, their operating behaviour is different.
The PRVV0842PE provides MOM-OFF operation, whereas the PRVV0840PE provides maintained ON-OFF operation. This distinction is important when servicing machinery because substituting one operating style for another could alter the way an operator command is issued.
Other Hercules selector options include PRVV0830PE, PRVV0831PE, PRVV0832PE, PRVV0833PE and PRVV0834PE, each offering a different combination of selector positions and operating functions. For this reason, the complete TER reference should always be checked when identifying a replacement.
Matching only the physical dimensions of a switch is not sufficient when selecting an industrial control component. Its switching sequence, number of positions, momentary or maintained action and electrical arrangement can all affect machine operation. Retaining the correct TER reference provides a more reliable basis for component identification.
Industrial Machinery Control Applications
Industrial joystick controls are widely used wherever an operator needs convenient and controlled command of machine movements and auxiliary functions. Typical environments can include material handling equipment, lifting machinery, industrial automation systems and other machinery requiring robust operator control interfaces.
Within such systems, the PRVV0842PE can provide a dedicated momentary selector command directly from a compatible Hercules joystick. The precise machine function controlled by the selector is application dependent and is determined by the equipment’s electrical design.
Locating an auxiliary selector within the joystick can reduce the need for the operator to move between separate controls while performing a machine operation. When correctly designed into the control system, this can contribute to a more logical and accessible operator interface.
Potential applications for a momentary selector input are determined entirely by the machine designer. Depending on the system, an auxiliary control might be associated with a temporary machine command, acknowledgement function, operational selection or another input required while the operator is controlling equipment. The PRVV0842PE itself does not determine the resulting machine action.
Operator Interface Flexibility
An effective industrial operator interface should provide the controls required for the task while keeping their operation clear and manageable. Combining primary joystick movement with selected auxiliary controls can help equipment manufacturers create a concentrated control interface for applications where operators need access to several commands during machine operation.
The PRVV0842PE supports this concept by providing a dedicated momentary selector option within compatible Hercules joystick configurations. The selector can complement the joystick’s primary movement functions while allowing an additional electrical input to be incorporated into the assembly.
For OEM applications, this flexibility can be useful when standardising a machine control station around a configurable joystick platform. Different Hercules configurations can be specified according to the number and type of auxiliary commands required for a particular machine.
Useful for Maintenance and Joystick Refurbishment
Industrial control equipment can remain in service for extended periods, making the availability of identifiable replacement components important for maintenance departments and service technicians. Individual joystick components may require replacement due to normal mechanical wear, damage or changes to the machine’s control requirements.
Where the remainder of a Hercules joystick remains serviceable, replacing the required component can provide a practical alternative to unnecessarily replacing an entire joystick assembly. The PRVV0842PE therefore has value not only for new joystick configurations but also as a replacement component for existing equipment.
During refurbishment, technicians should inspect the overall joystick condition rather than assuming that replacement of one component will address every issue. Associated wiring, connectors, mechanical components and other actuators should be checked as appropriate to the maintenance procedure.
Before removing an existing switch, recording the component reference and wiring arrangement can assist with subsequent identification and installation. Any replacement should then be checked for correct operation as part of the machine’s prescribed testing procedure before normal service resumes.
Genuine TER Component Identification
Using the TER reference PRVV0842PE provides a clear method of identifying the required selector switch. Part-number identification is particularly useful in industrial maintenance environments where multiple machines may use similar joystick assemblies with different internal configurations.
Recording the complete joystick model and individual component references during maintenance can make future servicing considerably easier. It also helps purchasing personnel communicate the exact replacement requirement when requesting quotations or technical assistance.
For organisations maintaining multiple pieces of equipment, accurate component records can also reduce uncertainty when spare parts are required later. Recording PRVV0842PE rather than simply describing the component as a two-position switch provides purchasing and maintenance teams with a much more precise reference.
Designed for Reliable Operator Command
Momentary selector switches are useful where machine designers require deliberate operator input without leaving the selector continuously active. With its MOM-OFF configuration, the TER PRVV0842PE provides this type of command within the compatible Hercules joystick architecture.
When the selector is incorporated into an appropriately designed machine control circuit, the operator can issue the required momentary input from the joystick itself. This makes the component particularly suitable for auxiliary commands that complement the primary directional functions of the joystick.
The PRVV0842PE should always be considered as part of the complete control system rather than as an independent safety or control device. Machine behaviour, interlocking and safety functions are determined by the complete electrical and control-system design.
Momentary Control Versus Maintained Control
Understanding the difference between momentary and maintained selector operation is important when specifying or replacing industrial controls. A maintained selector remains mechanically in its selected state until the operator deliberately changes its position. This can be appropriate where a mode or function needs to remain selected without continuous operator input.
A momentary selector operates differently. Its purpose is to provide a temporary input associated with deliberate actuation rather than remain continuously selected. The PRVV0842PE uses this MOM-OFF arrangement, distinguishing it from maintained ON-OFF selector variants available for the Hercules platform.
Neither operating method is universally preferable; the appropriate type depends on the machine function and control-system design. This is why the existing operating arrangement should be confirmed before ordering a replacement selector.
Correct Replacement Selection Matters
When ordering a replacement selector switch, confirming the full PRVV0842PE part number is recommended. TER’s Hercules range includes several selector variants, and differences in momentary or maintained operation can be significant even where the components appear similar externally.
Before replacement, technicians should verify the existing component, joystick configuration, wiring arrangement and required machine function. Where there is uncertainty regarding compatibility, technical advice should be obtained before installation.
This is particularly important when working on industrial machinery where an incorrectly specified operator control could result in unexpected machine behaviour. Replacement work should be undertaken by suitably qualified personnel and tested in accordance with the machine manufacturer’s maintenance procedures before equipment is returned to normal service.
Considerations When Ordering PRVV0842PE
Providing complete information when requesting a replacement joystick component can help minimise identification errors. The TER PRVV0842PE part number should be supplied wherever it can be confirmed from the existing component, machine documentation or joystick configuration information.
It can also be useful to provide the Hercules joystick model and details of the required selector operation. Where an existing component cannot be positively identified, photographs, equipment information and available joystick documentation may assist with determining the correct replacement.
Customers developing a new joystick configuration should consider the required switch action as part of the complete control design. The number of selector positions, momentary or maintained behaviour, contact requirements and intended joystick compatibility should all be established before final component selection.
Compact Auxiliary Control for Hercules Joysticks
One of the advantages of the Hercules joystick concept is the ability to incorporate auxiliary operator controls into the joystick handle configuration. This provides machine designers with flexibility when developing an interface around the functions that an operator needs during normal equipment operation.
The PRVV0842PE contributes to this modular approach by providing a two-position MOM-OFF selector option. Depending on the overall joystick configuration, other TER actuators and selector arrangements can be used to create an operator interface suited to the particular machine.
This configurability makes the Hercules platform suitable for applications where a standard directional joystick alone may not provide enough operator inputs.
Integration into New Equipment
Although the PRVV0842PE is valuable as a replacement component, it can also form part of a new compatible joystick configuration. OEMs and system integrators developing industrial machinery can use configurable joystick components to create an operator interface tailored to the functions of the equipment.
During the design process, the intended function of each joystick-mounted control should be clearly defined. Electrical characteristics, control-system inputs, operator ergonomics and machine safety requirements should be considered as part of the overall system rather than treating the selector as an isolated component.
Where MOM-OFF operation is appropriate, the PRVV0842PE provides a TER selector option specifically associated with the compatible Hercules joystick family.
Supporting Preventative Maintenance
Operator controls are routinely subjected to repeated use, making inspection of joystick components an important consideration within preventative maintenance programs. The appropriate inspection frequency will depend on the equipment, operating environment, duty cycle and recommendations of the machine manufacturer.
Maintenance personnel should investigate controls that display abnormal mechanical behaviour, physical damage, intermittent operation or other signs of deterioration. Identifying issues before a component becomes unusable can help maintenance teams plan replacement work rather than responding only after a control failure occurs.
Where a PRVV0842PE is identified as requiring replacement, confirming the component reference before ordering helps ensure that its MOM-OFF function is retained.

Its specific operating configuration also makes accurate identification particularly important. Customers requiring PRVV0842PE should ensure that MOM-OFF operation is appropriate rather than assuming that another two-position Hercules selector will provide equivalent behaviour.
Why Choose the Correct TER Selector Switch?
Selecting the correct joystick component helps maintain consistency between the operator interface and the original machine control design. In an industrial environment, even a seemingly small component such as an auxiliary selector can form an important part of how an operator interacts with equipment.
Using the correct PRVV0842PE reference provides confidence that the required selector configuration has been identified as a two-position MOM-OFF variant with one contact plus one common. This is particularly useful when distinguishing it from other Hercules selector options that use maintained action or alternative switching arrangements.
Whether the requirement involves planned maintenance, refurbishment, spare-parts inventory or a compatible new joystick configuration, accurate part-number identification remains one of the most important steps in the selection process.
