Why Choose the ABB M2SS3-20R Selector Switch?
The ABB M2SS3-20R, ABB order code 1SFA611202R2001, is a modular two-position momentary selector switch operator designed for industrial machinery, automation systems and operator control panels. Part of ABB's 22 mm modular Pilot Devices range, it provides spring-return operation for control functions where the selector should return automatically after release.
The M2SS3-20R features a red short rotary handle and a chrome-effect plastic front ring. Its non-latching, momentary operating principle makes it suitable for temporary machine commands, control sequences and other applications where an operator initiates a function by turning the selector and then releasing it.
Designed for standard 22 mm industrial pilot-device mounting, the M2SS3-20R is a non-illuminated front element with IP66 front protection and a NEMA 4X rating. ABB's modular construction allows the selector operator to be combined with compatible components to create the required electrical control arrangement.

Spring-Return Selection for Industrial Machinery
Momentary selector switches are useful where an operator needs to initiate a temporary machine or process command without leaving the control permanently selected. The ABB M2SS3-20R uses a spring-return, non-latching mechanism so the selector automatically returns after the operator releases the short rotary handle.
The M2SS3-20R combines this operating principle with a red actuator, chrome-effect plastic front ring and ABB's modular 22 mm pilot-device architecture. This makes it suitable for machine builders and control-panel manufacturers requiring a compact selector operator that can be integrated into a wider industrial control system.
Typical Applications
- Industrial machinery command functions.
- Operator stations and control consoles.
- Manufacturing and production equipment.
- Temporary machine and process commands.
- Conveyor and material handling systems.
- Process control and automation equipment.
- OEM machinery requiring spring-return selector control.
