Why Choose the ABB M3SS2-20U Selector Switch?
The ABB M3SS2-20U is a robust 3-position momentary selector switch designed for dependable operator control in industrial machinery, automation systems and electrical control panels. Part of ABB's modular pilot device range, it combines a short-handle actuator with spring-return operation and a grey non-illuminated control element.
This selector switch provides spring return from positions A and C to the central B position. When the operator releases the handle from either outer position, it automatically returns to B, making the M3SS2-20U particularly suitable for temporary commands, directional control, jogging and positioning functions.
The M3SS2-20U features a grey short handle with a chrome plastic bezel and is supplied without a contact block. Its modular construction allows compatible ABB contact blocks to be selected separately according to the electrical and switching requirements of the application.
Key Advantages
- Reliable 3-position momentary selector switch for industrial operator control.
- Spring return from A and C to B provides automatic centre return.
- Grey short-handle actuator provides intuitive manual operation.
- Chrome plastic bezel provides a clean and durable panel finish.
- Mechanical durability of 0.5 million operations supports long-term industrial use.
- Modular design enables compatible ABB contact blocks to be selected for the required control circuit.

Reliable Spring-Return Operator Control
Three-position momentary selector switches are particularly useful when an operator needs to issue temporary commands in either direction from a defined centre position. The ABB M3SS2-20U automatically returns from either outer position to B when released, supporting intuitive and repeatable control of machinery and industrial processes.
Its modular construction enables the selector switch operator to be combined with suitable ABB contact blocks according to the control circuit requirements. This flexibility makes the M3SS2-20U a practical choice for machine builders, panel builders and automation engineers creating customised industrial operator interfaces.
