Why Choose the ABB M3SSK3-101 Key Selector Switch?
The ABB M3SSK3-101 is a robust three-position momentary key-operated selector switch designed for industrial machinery, automation systems and electrical control panels. Part of the ABB modular pilot devices range, it provides key-controlled operation with spring return to the centre position for secure and dependable machine control.
The M3SSK3-101 has three positions, identified as A, B and C, with spring return from A and C to the centre B position. It uses key code 71 / Ronis 455, with the key removable in position B only, making it well suited to authorised momentary command functions where the control should automatically return to its normal centre state.
Designed for a standard 22 mm panel cut-out, the M3SSK3-101 features a black key actuator, non-illuminated construction and a black plastic bezel. The operator is supplied without a contact block, allowing suitable ABB modular contact blocks to be selected according to the control-circuit requirements, while IP66 front protection supports reliable operation in demanding industrial environments.

Secure Momentary Control for Industrial Machinery
Key-operated selector switches provide a practical method of restricting machine commands and control functions to personnel possessing the appropriate key. This helps reduce unintended or unauthorised operation while maintaining a straightforward operator interface for industrial machinery and automation equipment.
The ABB M3SSK3-101 combines three-position operation with spring return from either outer position to the centre B position. This arrangement is particularly useful for temporary directional, selection or command functions where the operator should automatically return to its normal centre state after the key is released.
Typical Applications
- Industrial machinery control panels.
- Authorised momentary machine commands.
- Manual directional control functions.
- Maintenance and service controls.
- Automation and production equipment.
- Motor and process control panels.
- OEM machinery and operator control stations.
