The working principle is as follows:
when the base is cut, one end of the first terminal 1 and one end of the second terminal 2, which are far away from the insulating shell 3, are pressed downwards, at the moment, the first connecting block 14 and the second connecting block 24 are used for supporting the first outer pin 12 and the second outer pin 22, so that the first outer pin 12 and the second outer pin 22 are not easy to move relative to the insulating shell 3, the connection between the first terminal 1 and the second terminal 2 and the insulating shell 3 is more stable and not easy to loosen, the probability of water permeating from gaps is reduced, meanwhile, when the base is used, the positions of the first terminal 1 and the second terminal 2, which extend out of the insulating shell 3, are penetrated by water, and the paths required to penetrate into the inner cavity of the insulating shell 3 are increased by the rough layer, the first connecting pin 13 and the second connecting pin 23, so that the water is not easy to permeate into the inner cavity of the insulating shell 3. The waterproof performance of the tact switch is increased.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
