Why Choose the ABB M3SSK3-301 Key Selector Switch?
The ABB M3SSK3-301 is a robust 3-position key-operated selector switch designed for industrial control panels, machinery and automation systems. Part of the versatile ABB Modular pilot device range, it provides key-controlled momentary operation for applications where machine or process functions require deliberate, authorised selection.
The M3SSK3-301 features momentary operation with spring return from positions A and C to the centre position B. Its black key actuator, chrome-metal bezel and non-illuminated design provide a durable operator interface suitable for demanding industrial environments. The key is removable in the centre B position only, helping maintain controlled access to the switching function.
Designed for standard 22 mm control-panel mounting, the M3SSK3-301 is supplied without a contact block, enabling compatible ABB modular contact elements to be selected according to the required control circuit. ABB identifies this exact selector switch under order code 1SFA611285R3001.

Controlled Momentary Selection for Industrial Machinery
Key-operated selector switches are well suited to control functions where access should be restricted to personnel carrying the appropriate key. The M3SSK3-301 combines this controlled access with spring-return operation, automatically returning the selector from either outer position to its centre position after the operator releases the key.
As part of ABB's modular pilot device system, the M3SSK3-301 can be incorporated into machine control panels and operator stations with compatible contact blocks selected for the required electrical function. Its modular construction simplifies configuration while providing a durable interface for industrial automation equipment.
Typical Applications
- Industrial machinery control panels.
- Key-controlled momentary machine commands.
- Machine setup and maintenance functions.
- Production and process equipment.
- Operator control stations and control desks.
- Industrial automation and OEM machinery.
