Rotary switch

Abstract

The invention discloses a rotary switch, comprising a bottom case, a shaft sleeve, a rotary shaft group, a first terminal and a second terminal; The first terminal is fixedly installed on the middle part of the bottom case, the second terminal is provided with a plurality of the first terminal holes and the second terminal holes, and the ring circumference is fixedly installed on the bottom case,and the bottom case is correspondingly provided with the first terminal hole and the second terminal hole. The rotating shaft group is rotatably mounted in the bottom case and can realize contact communication between the first terminal and any second terminal during the rotating process; The first terminal and the second terminal are arranged in an inverted L-shaped structure, and the bottom shell is correspondingly provided with a first embedding groove and a second embedding groove; The first terminal and the second terminal are respectively provided with a first positioning mount and a second positioning mount, and the bottom case is provided with a first positioning groove and a second positioning groove. The invention has simple structure, the shaft sleeve and the bottom shell are fastened and connected with the annular groove through the convex edge, and the first terminal and the second terminal are fastened and connected with the bottom shell, thereby saving the trouble of dispensing glue and reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of control switches, in particular to a rotary switch. Background technique [0002] A rotary switch is a switch that connects the first terminal and different second terminals by rotating to achieve different control purposes. It is often used in the fields of instrumentation, coffee machines and other household appliances. The bottom case, the rotating shaft group, the first terminal and the second terminal, wherein the first terminal and the second terminal are fixedly connected to the bottom case by means of dispensing. The dispensing process is cumbersome, resulting in higher production costs. During use, the first terminal and the second terminal are prone to be skewed and easily pulled out, which affects normal use and has room for improvement. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a rotary switch, which e...
