Abstract
The invention discloses a switch for an anti-theft device. The switch for the anti-theft device comprises a foundation seat, wherein an inner cavity is formed in the foundation seat and an opening of the inner cavity faces upwards. A strip-shaped lateral opening is formed in the wall of the front side of the inner cavity. An opening which is used for an installing spring fixing station is formed in the wall of the rear side of the inner cavity. Hooks are installed on the external surfaces of the wall of the left side and the wall of the right side of the inner cavity. First electric conducting terminals and Second electric conducting terminals which utilize integrated injection moulding process are inserted in the subface of the foundation seat. A handle is installed in the inner cavity. A spring positioning pillar, a movable spring installing boss which are opposite to the spring fixing station are installed on the rear end face of the handle from up to bottom. One end of a spring is fixed on the spring fixing station and the other end of the spring is sleeved on the spring positioning pillar. A movable spring sheet is installed on the bottom of the movable spring sheet installing boss, wherein touch spot of the movable spring sheet is in a U-shaped structure of double touch spots. A cover is provided with hanging platforms, wherein the hanging platform are matched with the hooks. The hooks are buckled in the hanging platforms, wherein the hanging platforms are located on the foundation seat. The switch for the anti-theft device is simple and compact in structure, small in size, space-saving and convenient to assemble. The switch for the anti-theft device not only can be used for circuit switching of the supermarket anti-theft device but also can be used for circuit switching of other electric equipment.
