产品描述

The E48 DIN-Style Safety Key Interlock Limit Switch is designed to be used with movable guards or covers which must be closed for operational safety. The key portion of the switch is affixed to the movable door, cover or other such guard. The switch itself is mounted to a rigid portion of the machine. When the guard is opened, the key is removed from the switch, thereby positively breaking the normally closed contacts. This interrupts the control circuit, stopping machine operation.
