Embodiment Construction

[0010] Such as figure 1 As shown, the present invention includes: a push rod assembly 1, a bushing 2, a housing 3, a rubber sealing sheet 4, a silver contact sheet 5, a small spring 6, and a socket assembly 7. The connection relationship is: the bushing 2 is press-fitted on the end face of the casing 3, the ejector rod assembly 1 is set at one end of the bushing 2, and a rubber sealing sheet 4 is arranged in the middle of the casing 3, and the rubber sealing sheet 4 There is a small boss in the middle part, the circular silver contact piece 5 and one end of the small spring 6 are set on the boss, and the other end of the small spring 6 is inserted into the groove on the pin seat assembly 7, while the pin There are two copper pins on the seat assembly 7, and the silver contacts and the copper pins are respectively used as two electrodes of the switch.

[0011] The thickness of the silver contact piece is 0.8mm, and an inner hole of ￠3. is added in the center as a positioning r...

Abstract

The invention relates to a backup light switch device, including: a support rod assembly, a lining jacket, a case, a spring, a rubber seal piece, a silver contact piece and a pin seat assembly. The support rod assembly is arranged at one end of the case, the middle in the case is provided with a rubber seal pad, the middle of the pad has a small boss, the circular silver contact piece and one end of the spring are covered on the boss, the other end of the spring is inserted in a groove of the pin seat assembly, and at the same time, there are two copper pins on the pin seat assembly. It overcomes the problem that the backup light is on or off because the switch seal pad of the backup light is easy to warp in the middle and the spring easy to deviate; enhances the life and reliability of the backup light switch, effectively avoiding the early invalidity.

Description

technical field [0001] The invention relates to a switch device, in particular to a reversing light switch. It belongs to the field of automotive electrical engineering. Background technique [0002] The reversing light is one of the most important safety parts in the vehicle, and its quality directly affects the performance of the vehicle. The reverse light switch is a safety component in the car transmission. In the past, the rework rate of the reversing light switch of foreign and domestic cars was relatively high (defects such as constant light or no light), and users complained quite seriously. Because of this small switch, it seriously affected the quality of the car brand. credibility. In order to prevent this phenomenon from happening again and eliminate potential safety hazards, corresponding solutions must be taken. After retrieval, Chinese patent name: reversing light switch, patent number: ZL 95211990.0. This patent adds a sealing rubber sleeve in the ordina...
