Emergency Stop Switches

Emergency stop switches are also frequently referred to as emergency off or kill switches. Emergency stop switches are used as a safety mechanism, typically for machinery, to cut off the electricity and stop operations during emergencies when a machine cannot be stopped safely or in its usual manner.

How does an emergency stop switch work?

Emergency stop switches are wired into the control circuits of the machines they’re attached to. When an emergency stop switch is pushed, this works as an instant circuit breaker, cutting the power to the circuit in question and stopping machinery from operating.

Can you bypass an emergency stop switch?

It is possible to bypass an emergency stop switch, if for example it fails to reset after operation. However, for safety reasons it is recommended you fix any problem with your emergency stop switch rather than bypassing it.

Why are emergency stop switches used?

Emergency stop switches are used as a means of averting and reducing hazards to workers, as well as to prevent damage to machinery or a product being built. The purpose of the emergency stop switch is to deliver this ability quickly when the normal stopping function is deemed inadequate to do so.

What should you do after pressing an emergency stop switch?

After dealing with the issue that required use of the emergency stop switch, you should pull out your emergency stop button and reset the circuit or machine. If pulling out the emergency stop switch immediately restores power, this is a potential safety issue.
