Why Choose the ABB M3SS2-20B Selector Switch?
The ABB M3SS2-20B 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 black 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 M3SS2-20B well suited to temporary commands, directional control, jogging and positioning functions.
The M3SS2-20B features a black short handle with a chrome plastic bezel and is supplied without a contact block. Designed for standard 22 mm pilot-device mounting, its modular construction allows compatible ABB contact blocks to be selected according to the electrical 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.
- Black short-handle actuator provides intuitive manual operation.
- Chrome plastic bezel provides a clean, durable panel appearance.
- IP66 front protection supports use in demanding industrial environments.
- Modular design enables compatible ABB contact blocks to be configured 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 M3SS2-20B automatically returns from either outer position to B when released, supporting intuitive and repeatable machine-control functions.
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 it a practical choice for machine builders, panel builders and automation engineers creating customised industrial operator interfaces.
Typical Applications
- Industrial automation control panels.
- Machine operator stations.
- Forward and reverse command functions.
- Jog and positioning controls.
- Production and processing machinery.
- Material handling equipment.
- OEM machinery and automation systems.
