Pull-wire switches are used to protect machines on long sections. A typical application is the protection of conveyors, where thanks to the cable switch, the operator has the option of emergency stopping the conveyor belt anywhere. The circuit breakers can be equipped with an E-Stop switch to enable the operator to stop the machine when the operator is close to the circuit breaker. In addition, the switch can be additionally equipped with a lamp indicating the state of the breaker. The use of a rope switch is cheaper than the use of traditional E-Stop, because with a single rope switch you can secure up to 100 meters of the conveyor belt. Circuit breakers can be mounted in two ways one switch and spring or 2 switches at both ends.
