Why Choose the ABB M3SS1-20R Selector Switch?
The ABB M3SS1-20R is a robust three-position maintained selector switch designed for industrial control panels, machinery and automation systems. Part of ABB's modular 22 mm pilot device range, it features a red short-handle rotary actuator with a chrome-plastic bezel for clear and dependable manual selection.
The M3SS1-20R provides three maintained positions, designated A, B and C, allowing the actuator to remain in the selected position until it is deliberately moved. This makes it suitable for operating-mode selection, machine-function control and other applications requiring three stable command positions.
Designed for standard 22 mm panel mounting, the M3SS1-20R is a non-illuminated modular selector switch operator. Its modular construction and ABB order code 1SFA611210R2001 make it a clearly identifiable component for machine builders, panel builders and industrial automation applications.

Reliable Three-Position Control for Industrial Machinery
Three-position selector switches provide operators with a straightforward interface for choosing between multiple machine states or control modes. The maintained action of the ABB M3SS1-20R keeps its short-handle actuator in the selected A, B or C position until another position is deliberately chosen, providing clear and predictable manual control.
The M3SS1-20R forms part of ABB's modular pilot-device system, enabling machine builders and panel designers to configure operator interfaces for a wide variety of industrial control functions. Its compact short handle, chrome-plastic bezel, standard 22 mm mounting format and robust front protection make it suitable for industrial machinery and automation equipment.
