Why Choose the ABB M2SSK4-101 Selector Switch?
The ABB M2SSK4-101 is a robust two-position key-operated selector switch designed for industrial control panels, machinery and automation applications where access to operating functions needs to be restricted. Supplied under ABB order code 1SFA611289R1001, it forms part of ABB's modular plastic pilot device range and provides reliable maintained operation for demanding industrial environments.
The M2SSK4-101 features a maintained two-position mechanism, meaning the selected position remains engaged after the key is turned. The key can be removed in position A only, providing controlled access to the alternative operating position and making the selector suitable for machine mode selection, maintenance controls and other authorised functions.
Featuring key code 455, a black key actuator and black plastic bezel, the M2SSK4-101 is a non-illuminated selector designed for ABB's modular 22 mm pilot device system. Its front-side IP66 protection rating and operating temperature range of -25 to +70 °C support reliable use in industrial control and automation equipment.
