Embodiment

[0022] Example: such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the present embodiment is a preferred embodiment of the present invention. The independent automobile window regulator switch in the present embodiment includes a base 3, a top pin 4, a movable contact piece 6, an elastic insulating member 5, a housing 2 and a button 1 .

[0023] The base 3 includes a bracket 32 ​​and a circuit board 31 on which two pairs of the first static contacts 7 and two pairs of the second static contacts 7a are installed. The lower end surface of the circuit board 31 has a Conducted pin 33, the first static contact piece 7 is used to control the rise of the glass lifter, and the second static contact piece 7a is used to control the lowering of the glass lifter, each pair of the first static contact piece 7 and the second static contact piece 7a disconnected from each other, two pairs of first static contact pieces 7 are arranged in parallel and connected in parallel wit...

Embodiment 2

[0029] Example 2, such as Figure 6 and Figure 7 As shown, the bottom of the ejector pin 4 of the independent automotive window regulator switch in this embodiment has a cylindrical pressure block 41a, and correspondingly, the upper end surface of the elastic insulating member 5 has a pressure groove 51a that cooperates with the pressure block 41a. If the cylinder fits, Guidance is worse than spherical fit.

[0030] The elastic insulating member 5 is flush with the circuit board 31 , and does not cover the entire circuit board 31 , so that the soldering feet 9 are exposed. The elastic insulating member 5 in this embodiment has two functions, first, as a transmission member between a movable contact piece and the ejector pin; second, as a reset member of the ejector pin, because it has certain elasticity.

[0031] Other structures are the same as in Embodiment 1.

Abstract

An independent auto glass lifter switch comprises a base (3), an ejector pin (4), a dynamic contact piece (6), a shell body (2) and a button (1); the upper end face of the base (3) is provided with static contact pieces (7,7a), and the lower end face is provided with a pin (33) conductively communicated with the static contact pieces (7,7a); the shell body (2) is arranged at the upper end part ofthe base (3); besides, the button is rotatably arranged at the upper end part of the shell body (2) and can drive the ejector pin (4), so that the ejector pin (4) can drive the dynamic contact piece (6) to achieve the connection and disconnection between the dynamic contact piece (6) and the static contact pieces (7,7a). The independent auto glass lifter switch is characterized in that the switchalso comprises a flexible insulator (5) arranged at the upper end face of the base (3) and contained in the shell body (2); the lower end face of the flexible insulator (5) is provided with the dynamic contact piece (6) corresponding to the static contact pieces (7,7a); and the upper end face of the flexible insulator (5) and the ejector pin (4) prop each other. Compared with the prior art, the independent auto glass lifter switch has the advantages that the switch has no spring reset mechanism and is restored, transited and driven through the flexible insulator; besides, the entire structureis compact and smart and is suitable for thinned and miniaturized product design.

Description

technical field [0001] The invention relates to a switch for automobiles, in particular to an independent automobile window lifter switch. Background technique [0002] The existing glass lifter switch adopts four pairs of clapping contacts. When the corresponding contacts are connected, the forward and reverse circuit of the corresponding glass lift motor is connected, thereby realizing the lifting of the glass. For example, the Chinese utility model patent "Automotive Window Regulator Switch" with the patent number ZL00232312.5 (authorized announcement number: CN2444805Y), the patent internally adopts a spring-type contact on-off structure, and the product has poor reliability and is easily damaged. It is also relatively large and cannot meet the installation requirements of the lifter. In addition, there is no indicator light setting on the inner wall. [0003] For this reason, the applicant discloses the Chinese utility model patent "Automobile Window Regulator Switch" ...
