The invention discloses an automobile combination switch which comprises a handle. A magnetic part is mounted on the handle, a Hall chip is fixedly mounted in a magnetic field range of the magnetic part, and the Hall chip is electrically connected to the main control board; the magnetic part moves relative to the Hall chip along with the operation of the handle so as to cause magnetic field change, and the magnetic field change is detected by the Hall chip and a signal is fed back to the main control board. The steering function and the light changing function are integrated on one magnet and one Hall chip, different signals are output according to different relative positions of operation, and the advantages that the number of parts is small, the structure is simple and reliable, occupied space is small, process assembling is simple, and the service life is long are achieved.
本发明公开了一种汽车组合开关,包括手柄;手柄上安装有磁性部,在磁性部的磁场范围内固定安装有霍尔芯片,霍尔芯片电连接至主控板;磁性部随手柄操作而相对霍尔芯片移动,籍以造成磁场变化,被霍尔芯片检测到并反馈信号至主控板。本发明在转向功能、变光功能集成在一个磁铁和一个霍尔芯片上,通过操作的相对位置不同而输出不同的信号,实现了零件数量较少,结构简单可靠,空间占用小,过程装配简单、耐久寿命高等优点。
