Abstract
The utility model relates to a dustproof multifunctional feather-touch switch. The dustproof multifunctional feather-touch switch comprises a cover plate, an inner button, an outer button, an elastic sheet, a dustproof layer, a terminal and a base, wherein the cover plate is internally provided with a cavity; the cover plate is provided with a through hole cooperating with the inner button and the outer button; the inner button and the outer button are partially arranged in the cavity through the though hole; the terminal is embedded in the base and is partially exposed outside the cavity; the end point of the elastic sheet is in contact with the surface of the terminal; and the dustproof layer is disposed between the elastic sheet and the inner button and is composed of a dustproof adhesive tape. The dustproof layer in the utility model is a film. By using the dustproof multifunctional feather-touch switch, dust, powder particles, soldering flux, dandruff of worker and the like can be effectively kept off above the dustproof layer and can be prevented from entering the terminal of the base, such that the service life of the switch is prolonged.
Description
Technical field
