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.
