Hinge-Operated Safety Switches

Where an attempt is made to open a protected door or flap during operation, the ATR hinge-operated switches and the ATR hasp-operated switches immediately disconnect the power supply to the machine or installation. Opening is registered at an angle of only 5 degrees, and so even tampering is not possible.
