Why Choose the ABB M3SS5-10U Selector Switch?
The ABB M3SS5-10U is a three-position momentary selector switch designed for industrial control panels, machinery and automation systems. Part of ABB's modular pilot-device range, it features a grey long-handle rotary actuator with a black plastic bezel for clear and convenient operator control.
The M3SS5-10U provides positions A, B and C with spring return from A to B and from C to B. Both outer positions are momentary, so releasing the handle automatically returns the selector to its centre B position, making it particularly suitable for temporary directional and machine-command functions.
Designed for standard 22 mm panel mounting, the M3SS5-10U is a non-illuminated modular operator supplied without a contact block. Its modular construction allows compatible ABB contact blocks and holders to be selected according to the required electrical switching arrangement.
Key Advantages
- Three-position momentary operation provides temporary commands in either direction.
- Spring return from A and C to centre position B automatically restores the neutral selection when released.
- Grey long-handle actuator provides convenient rotary operation.
- Black plastic bezel provides a practical industrial operator interface.
- Standard 22 mm panel mounting supports straightforward integration into operator stations.
- IP66 protection supports use in demanding industrial control-panel environments.
- Modular ABB construction allows compatible contact blocks to be selected for the required circuit.

Reliable Momentary Control for Industrial Machinery
Three-position momentary selector switches provide temporary operator commands while automatically returning to a defined neutral position. The ABB M3SS5-10U uses spring return from both A and C to centre position B, making it well suited to applications where either directional command should remain active only while the operator deliberately holds the selector.
The M3SS5-10U forms part of ABB's modular pilot-device system, allowing machine builders and panel designers to configure the operator with compatible contact blocks for the required control logic. Its grey long handle, black plastic bezel and standard 22 mm format provide a compact interface for industrial machinery and automation equipment.

- Industrial machinery control panels.
- Forward / centre / reverse momentary commands.
- Raise / neutral / lower control functions.
- Jogging and machine-positioning controls.
- Manufacturing and production equipment.
