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.
