The LS-Titan range of key interlock limit switches from Eaton is designed for monitoring the position of protective guards, such as doors, flaps, hoods and grilles. These switches are safety rated and include positive opening NC contacts meaning they cannot be defeated using basic tools such as pliers, screwdrivers and nails.

The LS-Titan range of limit switches includes 3 safety limit switch types: key interlock, door flap and door hinge switches. The key interlock switches are made up of the switch and the actuator (or key). The switch is mounted to a rigid section of the machine while the actuator is fixed to a movable guard. By opening the guard the actuator is no longer in physical contact with the switch, therefore positively breaking the NC contacts which interrupts the electrical control circuit, stopping the machine.

Door flap and door hinge limit switches are suitable when mounting actuator in the application is not possible. When an attempt is made to open the protected door hinge or flap during operation these limit switch systems automatically disconnect the power supply.

Eaton LS-Titan cold climate limit switches provide high personnel and process protection in industrial control applications. Designed for use in safety circuits, the limit switches are quickly installed, are flexible and safe whilst offering high reliability. The cold climate LS-Titan series allows the limit switches to be used in a wide operating temperature range.
