Why Choose the ABB M3SS2-20R Selector Switch?
The ABB M3SS2-20R is a robust three-position non-illuminated selector switch operator designed for industrial control panels, machinery and automation systems. Supplied under ABB order code 1SFA611211R2001, it forms part of ABB’s modular plastic pilot device range and provides dependable momentary control for industrial machinery and process applications.
The M3SS2-20R features a red short-handle operator with a chrome-plastic bezel. Its three-position mechanism provides spring return from A to B and from C to B, allowing temporary commands to be issued in either direction while automatically returning the selector to its centre position when released.
Designed for installation in a standard 22 mm mounting hole, the M3SS2-20R is supplied as a modular 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 function.

Reliable Momentary Control for Industrial Machinery
Three-position momentary selector switches are well suited to machine functions requiring temporary commands in two directions from a central resting position. The ABB M3SS2-20R provides positions A, B and C, with the mechanism returning automatically from either outer position to centre position B when the operator releases the handle.
ABB’s modular pilot-device construction allows the M3SS2-20R 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.
Typical Applications
- Industrial machinery control panels.
- Forward and reverse momentary commands.
- Raise and lower control functions.
- Left and right positioning commands.
- Automation and production equipment.
- Motor and process control stations.
- OEM electrical control systems and panel building.
