Anti-vibration signal switch

Abstract

The utility model relates to the technical field of electric switches, in particular to an anti-vibration signal switch, which is provided with a shell in which a circuit board and a movable contact frame are arranged, and is characterized in that the movable contact frame can be pushed by a push rod to move relative to the circuit board, a rivet is arranged on the inner side of the push rod, and the push rod is clamped at one end of the movable contact frame through the rivet. One end of the push rod is provided with a reducing insertion section, and gaps are arranged between the axial direction and the radial direction of the insertion section and the movable contact frame. A trigger mechanism of an existing signal switch is improved, an existing switch push rod is changed into a two-section structure, one section is matched with the trigger, the other section is matched with the electric brush through the electric contact frame, the two sections are connected through the rivet, and the two sections are in clearance fit, so that the influence of vibration of the trigger on the electric brush can be effectively reduced, and the service life of the switch push rod is prolonged. And the service life of the product is greatly prolonged.
