This Siemens 3SE5 232-0KC05-1CA0 mechanical position switch comes as a complete unit with a 31 mm wide plastic enclosure, one NO and two NC slow action contact, and a rounded plunger tip, and its increased corrosion protection makes it suitable for use in harsh environments, such as sea water and contact with detergents. The slow action normally-closed (NC) and normally-open (NO) contacts switch from closed to open and open to closed in proportion to the speed at which the switch is actuated, and the rounded plunger forcibly opens the NC contacts for use in safety circuits. The rounded plunger actuator tip can be rotated around the enclosure axis in increments of 22.5 degrees. This mechanical position switch conforms to the European Committee for Electrotechnical Standardization (CENELEC) EN 50047 standard for dimensions and mechanical data and the EN 50041 standard for quality assurance, and is suitable for use in applications in which there is push-type activation.

Mechanical position and safety switches are used to make or break electrical connections as part of a plant or building automation system. The switch is composed of a contact block with two or more contacts, an enclosure for protection, and an actuator head for monitoring object movement. Switch contacts can be normally open or normally closed, and switch connections can be either quick or slow, according to the requirements of an application, and they can include status LEDs and connector sockets. Actuator head types include rounded and roller plungers, roller and angular roller levers, spring rods, twist levers and rod actuators with a twist actuator, and fork levers with a twist actuator. Position and safety switches are used in applications such as elevators, emergency exits, and as emergency shutoffs in industrial workplaces.
