Siemens Emergency Stop Push Button, 10A Supply Current, Shock and Vibration Resistant - SIRIUS ACT Series - 3SU1851-0ND00-2AC2
Speedily bring moving equipment to a pause with this emergency stop push button from Siemens. It boosts workplace safety by offering a reliable way of halting hazardous industrial processes with just a push of its 40mm mushroom-shaped actuator. As a positive-latching model, it remains locked once pressed, meaning the machinery it controls will stay stationary unless you twist the button using its rotate-to-unlatch mechanism. This gives you peace of mind your machines won't resume operating until you've given the all-clear.
