Three-way switch

Abstract

The invention discloses a three-way switch, which comprises a base, an upper cover and a pressing unit, wherein the upper cover is assembled on the base; the top end of the upper cover is provided with an opening; the pressing unit passes through the opening, and extends out of the upper cover; a common terminal, three contact terminals and three movable contact springs which are correspondingly connected with the contact terminals respectively are arranged in the base; three corresponding normally-open ends are formed on the common terminal corresponding to the free ends of the movable contact springs; and the pressing unit comprises a pressing part, a first retaining part, a second retaining part and a third retaining part. Due to the adoption of an inching switch laminated design, the reaction sensitivity is high, the service life is long, and use cost is lowered; simultaneously, the three-way switch has the advantages of simple structure, small quantity of parts and convenience in assembling; and the common terminal, a first terminal, a second terminal and a third terminal are embedded and molded in the base at one time, so that the structures and arrangement of each terminal and the base are skillful and reasonable, the occupied space is small, and the three-way switch can better adapt to miniaturized electronic products.

Description

technical field [0001] The invention relates to the technology in the field of electronic switches, in particular to a three-way switch. Background technique [0002] At present, for example, the three-way switch used in the mouse generally adopts a sliding contact design, which has problems such as the short life of the key switch, especially in the Internet bar industry; and there are still many deficiencies in its own structure and performance. , For example: the switch response is not sensitive enough, the structure is more complicated, there are many parts, the assembly is inconvenient, the space is large, and it is not suitable for the use of miniaturized mice. [0003] Therefore, a new technical solution needs to be researched to solve the above problems. Contents of the invention [0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a three-way switch, which utilizes the superimposed design of...
