Why Choose the ABB M3SS7-31C Selector Switch?
The ABB M3SS7-31C is a 3-position maintained illuminated selector switch designed for industrial machinery, automation equipment and electrical control panels. Part of ABB's versatile Modular plastic pilot device range, it combines a clear illuminated short-handle actuator with a robust chrome-metal bezel.
Its maintained switching action allows the selected position to remain engaged after the operator releases the handle, making the M3SS7-31C suitable for machine mode, process and operating-state selection. The three-position configuration provides multiple selections from a single compact panel operator.
Designed for standard 22 mm control-panel mounting, the M3SS7-31C provides IP66 front protection for dependable use in demanding industrial environments. The selector is supplied without a contact block, allowing compatible ABB Modular contact and illumination components to be selected for the required electrical function.
