Emergency Stop Switches

Emergency stop switches, generally referred to as E-Stops, ensure the safety of persons and machinery and provide consistent, predictable, failsafe control response. A wide range of electrical machinery must have these specialized switch controls for emergency shutdown to meet workplace safety and established international and U.S. regulatory requirements.

E-Stops – critical human machine interface (HMI) devices – differ from simple stop switches (that merely turn equipment

off) in that they offer “foolproof” equipment shutdown. This is accomplished through advanced switch design that requires a twist, pull, or key to release electrical contacts to allow machinery restart. ■
