Plunger Plastic Switch

Plunger switch are electro-mechanical components that indicates the opening and closing of doors. It consist of a cylinder piston system in which the rod reciprocates within the the cylindrical body. The external casing is designed with the top grade of materials that prevents the abrasion and wear. Plunger switch sends electrical signal when the piston moves inwards the cylinder which indicates that the door is closed. It is equipped with a sensor and a magnet which acts as sensing elements to generate electric signals. It is used in various security systems to let it know that the gate has been opened.
