Emergency Stop Switch
Emergency Stop Switch
(OP)
Hello,
Are there any requirements/standards for Emergency Stop Switches for equipment? These would used to shutdown a piece of equipment for a emergency, either equipment failure or a personnel in harms way situation.
Should they be spring action return or maintained and manually reset?
Thank You

Sorry, I don't have any references, but in my opinion it would be beter if they are manually resettable. If the button is pressed, there is no way how the circuit could be energized without resetting the button. If the button is automatically resettable (spring action return), there is a chance for a remote start.

This method is recommended (mandated?) in one of the BSEN standards we operate, all depends on the risk assessment
