Why Choose the ABB M3SS2-31C Selector Switch?
The ABB M3SS2-31C is a robust 3-position illuminated selector switch designed for momentary operator control and visual signalling in industrial machinery, electrical control panels and automation systems. Part of ABB's Modular Plastic pilot device range, it combines a clear illuminated short-handle actuator with a durable chrome-metal bezel for a compact and professional operator interface.
The M3SS2-31C provides momentary operation with spring return from both A and C to the centre B position. This double spring-return arrangement makes it particularly suitable for temporary directional, positioning, jogging and other machine commands where the selector should automatically return to its neutral centre position when released.
Designed for standard 22 mm pilot-device mounting, the M3SS2-31C provides IP66 front protection and NEMA 4X protection for demanding industrial environments. Its modular construction allows compatible ABB contact blocks and illumination components to be selected separately according to the required control circuit.

Reliable Centre-Return Control for Industrial Machinery
Three-position centre-return selector switches are particularly useful where an operator needs to issue temporary commands in either direction from a neutral centre position. The ABB M3SS2-31C uses an A-B-C arrangement with spring return from both outer positions to B, allowing the handle to return automatically to the centre position after the operator releases it.
The clear illuminated operator provides visual signalling capability, while ABB's modular pilot-device architecture allows compatible contact blocks and illumination components to be configured according to the control-circuit requirements. This makes the M3SS2-31C well suited to new machinery, OEM control panels and compatible ABB pilot-device installations.
