Why Choose the ABB M3SS1-20B Selector Switch?
The ABB M3SS1-20B 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 black short-handle rotary actuator with a chrome-plastic bezel for clear and dependable manual selection.
The M3SS1-20B provides three maintained positions, designated A, B and C, allowing the actuator to remain in the selected position until it is deliberately moved. This latching operating principle makes it suitable for machine-mode selection, process control and other applications requiring three stable command positions.
Designed for a standard 22 mm mounting hole, the M3SS1-20B is a non-illuminated modular selector switch operator with IP66 front protection. Its modular construction allows it to be combined with compatible ABB holders and contact blocks to create the required electrical switching arrangement.

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 M3SS1-20B 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 M3SS1-20B forms part of ABB's modular pilot-device system, allowing machine builders and panel designers to combine the selector operator with compatible holders and contact blocks for the required electrical switching function. Its compact short handle, standard 22 mm mounting format and IP66 front protection make it well suited to industrial machinery and automation equipment.
