Why Choose the ABB M2SS2-21G Selector Switch?
The ABB M2SS2-21G, ABB order code 1SFA611201R2102, is a modular two-position illuminated selector switch operator designed for industrial machinery, automation systems and operator control panels. Part of ABB's modular plastic Pilot Devices range, it combines maintained selector operation with a green short-handle actuator for clear manual control and visual indication.
The M2SS2-21G features a green short rotary handle and matching green lens. Its two-position maintained, or latching, switching action allows the selector to remain in the chosen position after the operator releases the handle, making it suitable for machine modes, process functions and other applications requiring a persistent two-state selection.
Designed for standard 22 mm industrial pilot-device mounting, the M2SS2-21G provides IP66 front protection and a NEMA 4X rating when correctly installed. Its chrome-effect plastic bezel and modular ABB construction allow compatible contact blocks and illumination components to be selected according to the required electrical switching and signalling functions.

Maintained Selection and Visual Indication for Industrial Machinery
Maintained selector switches provide operators with a straightforward method of choosing between machine modes, process functions or operating states that need to remain selected. The ABB M2SS2-21G remains in its selected position after the short handle is released, making it suitable for applications where a persistent two-state selection is required.
The M2SS2-21G combines maintained switching action with a green short rotary handle, green lens and chrome-effect plastic bezel. As part of ABB's modular pilot-device system, compatible contact blocks and illumination components can be selected to create a control arrangement suited to industrial machinery, control panels and automation equipment.
