Multi-gear window lifting switch

Abstract

The invention provides a multi-gear window lifting switch, which prolongs the life of button switches, increases the hand feel of operation, and reduces the risk of misoperation. The multi-gear window lifting switch comprises a shell. Button bulge mounting plates are preinstalled on the shell. A button is installed between the two button bulge mounting plates through a rotating pin. At least two transmission parts are preinstalled inside the shell. In a closed state, the upper ends of the transmission parts protrude up to the lower pre-fitting surface of the button. The transmission parts are provided with corresponding key button bulges on the lower ends. All the soft key bulges are arranged on a soft key. A circuit board is arranged under the soft key. The lower end face of the button is recessed to form a guide slot. The upper end wall of the guide slot is of a raised circular arc structure which is composed of a plurality of continuous convex raised arc grooves. A piston mounting base is arranged at a position, corresponding to the guide slot, of the shell. The bottom of the piston is supported by a linear spring. The lower end of the linear spring is embedded into the piston mounting base.

Description

technical field [0001] The invention relates to the technical field of automobile push button switches, in particular to a multi-position window lift switch. Background technique [0002] The button switch is an important part of the car, especially the multi-stage button switch is widely used in the car. The existing multi-stage button switch is generally realized by adding an independent transmission part or adding a rod to the soft button. function, but because the life of the soft rubber itself and the size of the operating force are limited, it will affect the life and operating force of the entire switch product; in the traditional design method, its multi-position feel is achieved through soft buttons with plastic parts or metal However, the operating force of the soft keys cannot meet the high force value requirements, and the service life is limited, so in some cases it cannot meet the user's requirements. Contents of the invention [0003] In view of the above p...
