IN73 switches come in a plastic body and offer a modular, robust enclosure with a wide range of actuators made of metal. In mechanical and plant engineering, it is used as a position and safety switch in rough environments. MN78 is the metal version of the IN73 and is designed for use in very rough environments. MN78 features a modular, robust metal enclosure with a wide range of Metalast actuators. The standard IN62 switch is a basic switch. The actuators of the IN62 can handle lift/escalator applications. The standard IN65 switch is as effective as a molded plastic switch, as robust as a metal switch, and boasts a modular design with an easy-to-change actuator. The I81 position switch is the bistable version of the IN65 and acts as a latching switch.
