Why Choose the ABB M3SSC2-30B Selector Switch?
The ABB M3SSC2-30B is a robust 3-position momentary selector switch designed for dependable operator control in industrial machinery, automation systems and electrical control panels. Supplied under ABB order code 1SFA611251R3006, it forms part of ABB’s modular pilot device range and provides a practical interface for temporary machine and process control commands.
The M3SSC2-30B features a black short-handle actuator with a durable chrome-metal bezel. Its three-position A-B-C operating arrangement provides spring return from position A to B and from position C to B, so the selector automatically returns to its centre B position when released from either outer position.
This non-illuminated selector switch is supplied without a contact block, allowing compatible ABB contact blocks to be selected according to the required electrical switching configuration. Its centre-return action makes it particularly suitable for directional commands, positioning, jogging and other functions where a command should remain active only while deliberately selected by the operator.
Key Advantages
- Industrial 3-position momentary selector switch for machinery and automation applications.
- Spring return from A to B and C to B automatically restores the selector to its centre position.

Momentary Centre-Return Control for Industrial Automation
Momentary selector switches are particularly useful where an operator needs to issue temporary commands without leaving the control in the commanded position. The ABB M3SSC2-30B provides momentary selection in both outer positions, automatically returning from A to B and from C to B when the short handle is released.
This centre-return configuration is well suited to functions such as forward/reverse, raise/lower, left/right positioning and manual jogging. ABB’s modular pilot device architecture allows suitable contact blocks to be configured for the required electrical control circuit, while the chrome-metal bezel provides a durable operator interface for industrial control panels and machinery.
Typical Applications
- Industrial machinery control panels.
- Forward and reverse command functions.
- Raise and lower control functions.
- Left and right positioning commands.
- Manual adjustment and jogging controls.
- Factory automation systems.
- Material handling and production machinery.
- OEM machinery and operator stations.
