Why Choose the ABB M3SSC3-30B Selector Switch?
The ABB M3SSC3-30B is a versatile three-position selector switch operator designed for industrial machinery, automation systems and electrical control panels. Part of ABB’s modular pilot-device range, it features a black short-handle actuator with a durable chrome metal bezel for positive and clearly defined manual control.
The M3SSC3-30B combines maintained and momentary operation. Positions A and B are fixed, while position C provides spring return to B. Its M3SSC centre-block-operating design also provides additional flexibility when compatible ABB modular contact blocks are configured for multi-position control circuits.
ABB order code 1SFA611252R3006 identifies this exact M3SSC3-30B selector switch. The non-illuminated operator uses a standard 22 mm mounting hole, provides IP66 front protection and is supplied without contact blocks, allowing the switching arrangement to be configured separately for the application.

Flexible Centre-Block Control for Industrial Machinery
The ABB M3SSC range is designed for applications where a three-position selector requires flexible contact actuation across the left, centre and right operating positions. The M3SSC3-30B combines fixed positions A and B with a momentary C position that automatically returns to B when released.
Compatible ABB modular contact blocks can be arranged to create the required control logic, including configurations for separate circuits associated with the three selector positions. This flexibility makes the M3SSC3-30B suitable for machinery and automation systems requiring both retained selection and temporary control commands.
Typical Applications
- Industrial machine control panels.
- Factory automation equipment.
- Three-state machine control functions.
- Mode and function selection systems.
- Momentary commands combined with retained selection.
- Conveyors and material handling equipment.
- Production and process machinery.
- OEM machinery and electrical control systems.
