Two-way stop lamp switch

Abstract

The invention relates to a two-way stop lamp switch, which is characterized by comprising a shell, a base, a sliding block, a first movable contact piece, a second movable contact piece, a top rod, a first static contact piece, a second static contact piece, a first reset piece and a second reset piece, wherein the shell has an insertion hole; the base and the shell are assembled to form a hollowaccommodating cavity; the sliding block is arranged in the accommodating cavity; the first movable contact piece can be arranged on the sliding block in a vertical moving manner; two ends of the first movable contact are provided with two first movable contacts; the second movable contact piece is arranged on the sliding block and positioned below the first movable contact piece; two ends of the second movable contact are provided with two second movable contacts; and the top rod is inserted into the insertion hole of the shell, connected with the sliding block and can drive the sliding blockto vertically move in the accommodating cavity. Compared with the prior art, the invention has the advantages that: the two-way stop lamp switch is simple and compact in overall structure and reasonable in structural arrangement, and can realize one-on one-off two-way control.

Description

technical field [0001] The invention relates to a brake light switch, in particular to a brake light switch capable of controlling two circuits. Background technique [0002] Existing motor vehicle brake light switch see figure 1 As shown, it includes a base 6a, a screw sleeve 23a, an insulating sleeve 8a, a connecting wire 9a and a socket seat 1a, and a pair of elastic contact pieces are arranged on the base 6a, and the elastic contact pieces protrude from the rear end surface of the base 6a to form a connecting piece 10a , the rear end of the screw sleeve 23a is a sleeve 2a and is sleeved on the front surface of the base 6a and covers the elastic contact piece. The front end has a hollow screw rod 3a, and a column rod 4a is elastically arranged in the hollow screw rod 3a through a spring. And the tail end acts between the elastic contact pieces, a pair of plug pins 5a are provided in the socket seat 1a, two connecting wires 9a are connected to the corresponding connecting...

Problems solved by technology

Although the product application of this design is relatively common, there are deficiencies: first, there are many parts, cumbersome connection, and troublesome assembly; second, the connection at both ends of the wire is realized by soldering, and if the voltage is unstable, it is easy to burn out and blow out , affect the normal use of the brake light; finally, the function is relatively single, it can only realize the switch of the brake light, and cannot cooperate with other mechanisms of the car, such as the control of the automatic transmission on the automatic transmission car
