Switch device for automobile brake lamp

Abstract

The invention discloses a switch device for an automobile brake lamp. The switch device comprises a box body, a sliding shaft, a terminal box, a sliding shaft resetting spring, an action terminal resetting spring, an action terminal and two fixed terminals, wherein the box body is provided with a through hole and a receiving groove which are respectively arranged up and down and are mutually through; the sliding shaft is arranged in the through hole in a sliding mode; the lower end of the sliding shaft is provided with a clamping part positioned in the receiving groove; the top wall of the receiving groove extends downwards to be provided with two circular guiding columns and two spacing ribs; the two circular guiding columns are arranged on the side of the through hole; the clamping part is arranged between the two circular guiding columns and the side wall of the receiving groove; the clamping part and the circular guiding columns form linear contact; the two spacing ribs are arranged on the other opposite side of the through hole; and the two spacing ribs are respectively correspondingly arranged on the inner sides of the two fixed terminals. The switch device for the automobile brake lamp, provided by the invention, has the advantages of reduction of manufacturing cost and excellent durability.

Description

technical field [0001] The invention relates to a switch, in particular to an automobile brake light switch device. Background technique [0002] Existing automobile brake light switch is made up of handle knob, box body, slide shaft, terminal box, two fixed terminals, action terminal, two groups of auxiliary terminals, slide shaft return spring and action terminal return spring. [0003] Wherein, the handle knob is fixed on the box body; the box body is composed of a screw rod and a base located below the screw rod, the center of the screw rod is provided with a through hole, the base part is provided with an accommodation groove, the through hole runs through the accommodation groove, and the top wall of the accommodation groove is provided with two Limiting ribs, two limiting ribs are distributed on both sides of the through hole; the sliding shaft is slidably set in the through hole of the box body, its upper end is exposed outside the screw rod, the lower end extends in...

AI Technical Summary

Problems solved by technology

During the sliding process of the sliding shaft, the limiting rib and the holding part of the sliding shaft are always in surface contact, so the sliding resistance of the sliding shaft is large, which affects the operating performance of the sliding shaft and is inconvenient to operate

[0005] In addition, although the technology of installing the two fixed terminals and plastic inserts in the terminal box can prevent the fixed terminals from toppling over, the molding of the inserts makes the mold cost high, which is not conducive to the long-term development of the enterprise
