Steering wheel combination switch

The application discloses steering wheel combination switch, including casing, handle components and circuit board, the circuit board is located handle components's top and install in the top of casing is still including locating on the circuit board, be used for detection direction dish rotation angle's angle measure component. In view of the circuit board install in the top of casing, and be located handle components's top, so handle components's lubricating grease reaches the unable drippage of comdenstion water in the casing extremely on the circuit board, reduced the risk that the circuitboard broke down makes circuit board job stabilization nature promotes to some extent. Again because the angle measure component is located on the circuit board, the two set is as an organic whole, the nature the angle measure component with connection between the circuit board is more firm, the job stabilization nature of circuit board further promotes to some extent. Consequently, the steeringwheel combination switch's
