Emergency Stop Switch

with Manual Reset

This example shows dual channel door switches with automatic reset

and a dual channel emergency stop switch with manual reset. Each

pair of door switches controls a separate zone, so part of the machine

can keep running if that part's door is closed. An E-stop will stop

both zones.
