Why Choose the ABB M2SS1-21L Selector Switch?
The ABB M2SS1-21L, ABB order code 1SFA611200R2104, 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 blue short-handle actuator for clear manual control and visual indication.
The M2SS1-21L features a blue short rotary handle and matching blue illuminated lens. Its two-position maintained, or latching, 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 manual selection.
Designed for standard 22 mm industrial pilot-device mounting, the M2SS1-21L provides IP66 front protection and a NEMA 4X front enclosure rating when correctly installed. Its chrome-effect plastic front ring and modular ABB construction provide a practical operator interface that can be integrated with compatible switching and illumination components.

Maintained Selection and Visual Indication for Industrial Machinery
Maintained selector switches provide operators with a straightforward way to choose between machine modes, process functions or operating states that need to remain selected. The ABB M2SS1-21L remains in its selected position after the short handle is released, making it well suited to applications where a persistent two-state selection is required.
The M2SS1-21L combines maintained switching action with a blue illuminated short handle and chrome-effect plastic front ring. As part of ABB's modular pilot-device system, it can be integrated with compatible switching and illumination components to create a control arrangement suited to industrial machinery, control panels and automation equipment.
