Hinge Operated

Sentrol Industrial Hinge Operated Safety Switches utilize a rotating shaft to provide a positive means of turning the control power off should an access panel, door, gate, guard, etc. be rotated open during machine operation. The switch operating shaft is designed to be in line with the rotation point of the door and uses the opening force of the door to rotate the safety switch operating shaft. When the access panel, door, gate, guard, etc. is rotated to the "open" position, the normally closed contacts in the safety switch are mechanically forced open turning off the control power in the machine - disabling the machine. Since the switch contacts can only be closed when the shaft is rotated to the closed position, the machine cannot be re-started until the door, gate, guard, etc. is closed.
