Eaton M22-PVS-MS2 Emergency Stop Key Release Mushroom Head Actuator, Red/Yellow, 22.5 mm 111771

In industrial control panels, an emergency stop must be impossible to ignore and impossible to reset by accident. The Eaton M22-PVS-MS2 is a key-release emergency stop actuator with a red mushroom head on a yellow background, built for 22.5 mm panel cut-outs. It latches when pressed and stays locked until an operator deliberately turns the MS2 key, preventing unauthorized or accidental restarts.

Who is it for

Machine builders, panel builders, and maintenance teams who need a tamper-resistant E-stop that meets IEC/EN 60947-5-1 and stands up to washdown environments.
