Abstract
The invention discloses an electronic thin-film switch. The electronic thin-film switch comprises a metal elastic chip and a thin-film panel. The metal elastic sheet is fixed to a flexible circuit board. An isolation layer is arranged between the contact surfaces of the flexible circuit board and the two ends of the meal elastic sheet. An isolation cavity is formed between the metal elastic sheet and the flexible circuit board. Isolation protruding points are arranged in the isolation cavity. The isolation protruding points are arranged on the flexible circuit board at the position corresponding to the metal elastic sheet. A back glue layer is arranged at the bottom of the flexible circuit board. A release paper layer is arranged on the surface of the metal elastic sheet, and the thin-film panel is arranged on the surface of the release paper layer. The electronic thin-film switch has the advantages that the hand feel of keys is comfortable, the accuracy of the keys is improved, flexibility and convenience are achieved, the universality of the thin-film switch is improved, operation is convenient and fast, and the service life is prolonged.
Description
Technical field
The present invention relates to thin film switch, relate in particular to a kind of electronic membrane switch.
