As a preferable technical scheme of the utility model, the middle part of the cover plate is provided with a button hole, and one end of the button is matched with the button hole.

As a preferable technical scheme of the utility model, two clamping holes are formed in one side of the top of the cover plate, two clamping blocks are arranged on one side of the top of the base, and the clamping blocks are matched with the clamping holes.

As a preferable technical solution of the present invention, the button is filled with a solid material.

As a preferable technical scheme of the utility model, the Mylar and the reed are both circular in shape, and the reed is matched with the cavity in the base.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the on-off state of the switch is switched by the reed, when the button is pressed to a certain degree, the click sound is generated, the solid material is filled in the button, so that the static strength reaches more than 6KG, the reed is sealed in the cavity in the base through Mylar, the situation that dust and the like enter the base through the button hole in the middle of the cover plate to corrode the reed in the base is prevented, and the service life of the tact switch is prolonged.
