Why Choose the ABB M3SS5-31G Selector Switch?
The ABB M3SS5-31G is a robust three-position momentary illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Part of ABB’s modular pilot device range, it combines a green long-handle actuator with a durable chrome metal bezel for clear and dependable operator control.
The M3SS5-31G provides momentary operation with spring return from positions A and C to centre position B. When released from either outer position, the actuator automatically returns to B, making the selector particularly suitable for temporary directional, jog and positioning commands.
ABB order code 1SFA611214R3102 identifies this exact M3SS5-31G selector switch. The illuminated operator is supplied without a contact block, allowing compatible ABB contact blocks and holders to be selected according to the required electrical control function.

Reliable Momentary Control for Industrial Machinery
Selector switches provide operators with a straightforward physical interface for issuing machine commands and controlling industrial processes. The ABB M3SS5-31G is particularly useful where commands should remain active only while the operator deliberately holds the selector in one of its outer positions.
With spring return from both A and C to centre position B, the M3SS5-31G is well suited to functions such as forward/reverse movement, raise/lower commands and manual jogging. Its illuminated green actuator enhances visual identification, while the modular ABB construction allows the required contact arrangement to be created using compatible contact blocks.
Typical Applications
- Industrial machine control panels.
- Factory automation equipment.
- Forward and reverse control commands.
- Raise and lower control functions.
- Manual jog and positioning controls.
- Conveyors and material handling systems.
- OEM machinery and electrical control systems.
