Siemens 3SE03-SA Limit Switch Plug-in Module - Single Pole 1NO+1NC for 3SE03 North American Limit Switches | Industrial Automation & Machine Control Solution

Mechanical limit switches are used to make or break electrical circuit connections as part of a facility automation system. The switch is composed of a contact block with one or more electrical contacts, wiring connections, an enclosure for protection, and an actuator head for tracking object movement. Switch contacts can be normally open or normally closed, and switch connections can be either quick or slow, depending on the switch design, 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. Mechanical limit switches are used in many applications such as elevators, conveyors, doors, water tanks, railroad crossings, emergency exits, and as emergency shutoffs in industrial workplaces.
