Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Specifically, referring to fig. 1 to 3, a switch integrated on a steering wheel skeleton and having vibration feedback comprises a steering wheel body 1, wherein the steering wheel body 1 comprises a spoke support 11, and a vibration feedback switch 2 is fixedly connected to the spoke support 11. Vibration feedback switch 2 includes elastic connection spare 21, support frame 22, vibrations drive element 23, circuit board 24, operating assembly 25, elastic connection spare 21 is metal shrapnel or spring, elasticity has, elastic connection spare 21 one end and spoke support 11 fixed connection, the other end and support frame 22 fixed connection, support frame 22 is fixed in spoke support 11 top, support frame 22 and vibrations drive element 23 fixed connection, vibrations drive element 23 is located support frame 22 downside, operating assembly 25 and support frame 22 fixed connection, operating assembly 25 is located support frame 22 upside, circuit board 24 sets up in spoke support 11 bottom side, this makes circuit board 24 and operating assembly 25 separately set up, avoid the electromagnetic interference that operating assembly 25 produced circuit board 24, the job stabilization nature is improved.
