The invention discloses a steering column switch.The steering column switch comprises a light-proof cavity and a supporting part which is arranged in the cavity and provided with the preset number of light through holes arranged in sequence, and each light through hole is provided with a luminous body emitting default color light; the steering column switch further comprises a sliding block, a color sensor located in the cavity and a pushing rod which is located outside the cavity and connected with the sliding block, wherein the sliding block is located above the light through holes and shields the light through holes, the sliding block is provided with a light hole, and the pushing rod is used for driving the sliding block to slide to enable the light hole to be aligned with any light through hole formed in the supporting part.According to the steering column switch, light with different colors serves as different switch gears, and corresponding selected switch gears are identified by identifying colors of transmitting light; compared with an existing steering column switch, the steering column switch is low in cost, and the defect that mechanical wear is prone to cause failure is overcome.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a steering column switch. Background technique [0002] In the prior art, the steering column switch of an automobile is an electrical contact type, including a lever, a gold-plated sliding contact piece and a printed circuit board. By turning the lever, the internal gold-plated sliding contact piece is driven to come on the gold-plated pad of the printed circuit board. Slide back to realize the switching of the switch gear. [0003] For the sliding contact structure in the steering column switch, due to the high life expectancy of the steering column switch, the sliding contact piece and the circuit board of the gold-plated process are used, which can increase the service life of the switch, but at the same time, the cost is too high; The structure of the contact sheet is prone to mechanical wear when used for a long time, which may easily lead to switch failure.
