Why Choose the ABB M3SS4-10R Selector Switch?
The ABB M3SS4-10R is a robust three-position maintained non-illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Supplied under ABB order code 1SFA611213R1001, it forms part of ABB’s modular plastic pilot device range and provides dependable manual mode and function selection.
The M3SS4-10R features a red long-handle operator with a black plastic bezel. Its three-position A-B-C mechanism uses maintained operation with no spring return, allowing the selected handle position to remain in place until it is deliberately changed by the operator.
Designed for ABB’s 22 mm modular pilot device system, the M3SS4-10R is supplied as a selector switch operator without a contact block. Its modular construction allows compatible ABB holders and contact blocks to be selected according to the required electrical switching arrangement.

Reliable Maintained Control for Industrial Machinery
Three-position maintained selector switches are well suited to machine functions where an operator needs to select and retain one of several operating states. The ABB M3SS4-10R provides three positions, A, B and C, with a latching mechanism that keeps the long handle in the selected position rather than automatically returning it when released.
ABB’s modular pilot-device construction allows the M3SS4-10R to be combined with compatible holders and contact blocks according to the required electrical switching arrangement. This flexibility makes the selector suitable for new machinery, control-panel construction, system integration, maintenance and replacement applications.
