Abstract:
A safety switch mounted in an electronic device comprising:a seat having one of a variety of shapes, the seat comprising an opening at one side, at least one snapping member at either edge of the opening so as to fasten the seat to a predetermined position of the electronic device, and a gap on the bottom of the opening; a cavity provided in the opening; a first cylinder provided in the opening; a second cylinder provided in the opening and spaced apart from the first cylinder; and a trigger switch fitted in the cavity of the opening, the trigger switch comprising a signal cable extended therefrom wherein one end of the signal cable is formed as a connector, the signal cable runs the lower surface of the first cylinder prior to going up to run the upper surface of the second cylinder, and the signal cable passes through the gap on the bottom of the opening for exposing the connector, whereby an additional support is provided to the signal cable by both the first and second cylinders as a pulling force is exerted on the signal cable for preventing the pulling force from transmitting to the trigger switch along the signal cable to cause a poor contact of the trigger switch with the signal cable or a disengagement of the trigger switch from the signal cable.
