Detailed Description
The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 to 5, a button device suitable for a circuit board comprises a button switch body 1 (the top of the button switch body 1 is provided with an elastic button 11), wherein the button switch body 1 is a conventional pin-type button switch disclosed on a circuit board of the prior art, and the top of the button switch body 1 is provided with the elastic button 11.
Based on the button switch body 1 pin that prior art discloses is not hard up easily, the utility model discloses make following technological improvement:
the button switch comprises a button switch body 1, wherein pins 12 are fixedly connected to the front side wall and the rear side wall of the button switch body 1; the button switch body 1 is provided with four folding corner parts; all be equipped with installation screw member 2 on the dog-ear position of button switch body 1, installation screw member 2 includes threaded sleeve 22, threaded connection has installation screw rod 21 on the threaded sleeve 22.
Specifically, the push switch body 1 is provided with a through hole that is fitted to the threaded sleeve 22, and the threaded sleeve 22 is located in the through hole.
