Embodiment 1

[0018] Embodiment one, see figure 1 , a door and window lift switch assembly for automobiles, including a base 71 and a housing 72. The base 71 and the shell 72 are detachably connected together by buckles. An outer side of the base 71 is provided with mounting feet 711 . The inner side of the base 71 (the side facing the housing) is provided with a PCB circuit board 73 . The PCB circuit board 73 is provided with pins 731 and fixed contact pairs electrically connected with the pins. A fixed contact pair consists of two fixed contacts. The fixed contacts of the fixed contact pair are electrically connected to pins 731 . The PCB circuit board 73 is covered with a conductive rubber plate 74 . The portion of the conductive rubber plate 74 corresponding to the pair of fixed contacts elastically arches upward to form a movable contact. The moving contact is disconnected from the fixed contact. The shell 72 is also provided with a button 75 . During use, the present invention...

Embodiment 2

[0019] Embodiment two, the difference with embodiment one is:

[0020] see figure 2 , the shell 72 is provided with a via hole 721 . The movable contact 741 is provided with ferromagnetic particles 742 .

[0021] The PCB circuit board 73 is provided with an electromagnet 733 surrounding the periphery of the fixed contact pair 732, that is, the electromagnet 733 is ring-shaped, and the two fixed contacts 7321 forming the fixed contact pair 732 are all located in the circle surrounded by the electromagnet 733. the interior of the space. The electromagnet 733 is provided with a pair of magnet portion contacts 7331 . The electromagnet 733 is energized to generate magnetic force when the pair of contacts 7331 of the magnet part are turned on. The contacts 7331 of the magnet portion are linear structures extending along the distribution direction of the fixed contacts 7321 and the movable contacts 741 . The surface 7332 opposite to the contacts of the magnet part is a concave ...

Abstract

The invention provides an automobile door and window elevating switch assembly, which relates to automobile switches, and comprises a base and a housing connected to the base. A PCB circuit board is disposed between the base and the housing. The PCB circuit board is provided with a pin and a fixed contact pair electrically connected to the pin. The housing is provided with a button. The PCB circuit board is covered by a conductive rubber plate, which arches upwardly and elastically at the part corresponding to the fixed contact pair, forming a movable contact disconnected from the fixed contact. The invention is advantageous in that the noise of contact contacting is low with the use of the automobile door and window elevating switch assembly, and the problem of the prior art that the noise of contact contacting is loud can be resolved.

Description

technical field [0001] The invention relates to a switch on an automobile, in particular to a door and window lift switch assembly for an automobile. Background technique [0002] The car is set on the car door, and the lifting of the window is controlled by a switch, wherein the switch is set on the car door and the dashboard of the cab (hereinafter, the switch that is set on the dashboard to control the lifting of the window on the car door is called the car door and window. Lifting switch assembly), the door and window lifting switch assembly for automobiles includes four lifting switches and a locking switch, the four lifting switches control the lifting of the windows on the four doors one by one, and the locking switch makes the setting The switches on the doors do not control the windows up and down. [0003] Existing automobile door and window lifting switch assembly comprises base and the shell that is connected on the base, is provided with PCB circuit board betwe...
