Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, 2 and 6, the push button sunroof switch in the present embodiment includes a housing 1, a push button 3, a bottom cover 2, a circuit board 5, a slider 4, and a contact bridge 7.

As shown in fig. 3, a first partition plate 11 and a second partition plate 12 are formed at an interval in the middle of the casing 1 to divide the casing 1 into a first region, a second region 15, and a third region 14 in the horizontal direction in this order, the first region is formed with a notch 13, the second region 15 is hollow, and the third region 14 is also hollow. Shaft holes 16 are respectively formed at both sides of the upper port of the housing 1.

The two sides of the middle part of the button 3 are formed with shaft parts 33 which are rotatably matched with the shaft holes 16. The shaft portion 33 is engaged with the shaft hole 16, and the push button 3 is rotatably provided at the upper end of the housing 1. The ball 6 with the adaptation of gear groove 13 is equipped with in 3 lower extreme one sides of button elastically, specifically, 3 lower extremes of button extend has extension post 31, and the shaping has the spring groove in the extension post 31, and the spring inslot is equipped with gear spring 61, and ball 6 adaptation offsets in spring groove port and with gear spring 61.
