International standards state that emergency-stop functions must trigger on a single human action using a manually actuated control device. Equipment designers must also consider safety functions, such as reversal or limitation of motion, deflection, shielding, braking, and disconnecting. An E-Stop is only one part of a comprehensive safety system. Simply stated, E-Stops should go on all machinery except for that in which an emergency-stop function would not lessen the risk. In addition, international standards may differ from local standards and compliance needs. Unfortunately each area also has its own compliance requirements that designers must know. Virtually all industry segments mandate E-Stops for safe operation. These realities have forced switch companies to improve switch reliability and, thus, safety. Problems arise when contact blocks and actuators are improperly installed or if they separate because of vibration or other malfunctions. Innovative switch designs prevent blocking, a wanton or accidental obstruction of the actuator with foreign objects, and teasing, a momentary actuation without latching the power circuit open, that may give premature or unreliable operation.

This takes place through switch designs that need a twist, pull, or key to release the electrical contacts so the machinery can restart. E-Stops differ from simple stop switches that merely turn equipment off in that they offer foolproof equipment shutdown. A wide range of electrical machinery need these specialized switches to meet workplace safety and established international and domestic regulatory requirements.
