1SFA611201R2001 ABB M2SS2-20R Red 2-Position Maintained Selector Switch
ABB M2SS2-20R is a red short-handle 2-position maintained non-illuminated selector switch operator with A/C positions, a chrome-finish plastic bezel and 22 mm panel mounting for industrial machinery and automation control applications.
The ABB M2SS2-20R is a 2-position maintained selector switch operator designed for industrial machinery, automation systems and electrical control panels. Part of the ABB Modular 22 mm pilot device range, it provides dependable manual selection between two stable operating positions.
The M2SS2-20R features a red short-handle actuator with a chrome-finish plastic bezel. Its maintained A/C operating principle means the selector remains in either selected position after the handle is released, making it suitable for mode selection and other control functions requiring a persistent command.
Designed for a standard 22 mm panel cut-out, the M2SS2-20R is non-illuminated and supplied without a contact block. Its modular construction allows compatible ABB holders and contact blocks to be selected separately according to the electrical switching arrangement required by the application.
