Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a dabbing switch with dustproof construction, include switch body 1 and install button 8 and pin 7 on switch body 1, switch body 1's top is fixed with annular frame 9, the outside cover of button 8 is equipped with dirt proof boot 5 and the outside shaping of dirt proof boot 5 has annular limit 13, dirt proof boot 5 is the rubber material, when pressing button 8, dirt proof boot 5 takes place to be out of shape, the inner chamber space of annular frame 9 is used for holding annular limit 13, it has closing cap 10 to close soon through the screw thread on the annular frame 9, the outside shaping in bottom of closing cap 10 has the clamping ring 12 that contacts with annular limit 13, closing cap 10 closes under the connected state with annular frame 9 soon, clamping ring 12 extrudees annular limit 13, can avoid the dust to get into, sealed effect has been played, annular limit 13 is the rubber material, make the contact of annular limit 13 and clamping ring 12 inseparabler.
