Carlo Gavazzi also offers a complete range of safety switches. Cable safety switches are essential for the continuous control of a long line of machines or on conveyor systems. They guarantee the safety of the operator, who is able to immediately stop machinery by pulling on the wire. Key type switches are used to prevent machinery from being started without the key in place. Once the key is inserted, the machinery may be started. Hinge type switches operate when the arm has been moved a certain number of degrees. They are frequently used to stop machinery in the event a door or gate is opened. With manual reset types, once the limit switch has been activated by the actuator arm, the switch may only be reset by pulling the blue rearm button. These types of limit switches are frequently used in mechanical and hydraulic hoists and lifts.
