Problems solved by technology

[0003] The existing automobile combination switch mostly adopts the contact sliding switch mode. The combination switch works frequently for a long time, which will cause wear between the contact systems. When the wear is serious, it will lead to poor contact of the contact system, affecting the performance of the switch, and the service life is short.

Abstract

The invention discloses a combination switch which is used on an automobile. The combination switch is characterized in that a parallel plate capacitor is composed of two electrodes on a circuit control board, an insulation slide block can slide into a space between the two electrodes, the insulation slide block is connected with a deflector rod, the deflector rod drives the insulation slide block to slide between the two electrodes so as to change capacitance value of the parallel plate capacitor and measure the capacitance value, a function corresponding to the capacitance value of a current gear position of the deflector rod is achieved by correlating the capacitance value obtained through measurement with a preset function threshold, and functions of the combination switch can be achieved through a non-contact mode.

Description

Technical field [0001] The invention relates to the field of automobile control, in particular to a combination switch. Background technique [0002] Automobile combination switches are generally set on the steering column of the automobile and are mainly used to adjust automobile lights, wipers and cruise functions. [0003] Existing automobile combination switches mostly adopt contact sliding switch mode. The frequent operation of the combination switch for a long time will cause wear between the contact systems. When the wear is serious, the contact system will be poorly contacted, which affects the performance of the switch and has a short life. . Summary of the invention [0004] In view of this, the main purpose of the present invention is to provide a combination switch, which can realize the function of the combination switch in a non-contact manner. [0005] In order to achieve the above objective, the present invention provides a combination switch, which is applied to aut...
