Abstract

The invention discloses a rotary switch and a control method thereof, comprising a PCB board, a dome, a first rotating mechanism, a second rotating mechanism, a rotating cap, a contact piece, and screws, and the second rotating mechanism is fixed on the PCB board through screws , the second rotating mechanism is connected with the first rotating mechanism, one end of the first rotating mechanism is connected with the rotating cap, the other end of the first rotating mechanism is connected with the contact sheet, the contact sheet is connected with the dome, and the dome is connected with the PCB board catch. The rotary switch of the present invention realizes different gears when rotating through the plastic structure, and the plastic of the rotating part rotates to different positions to drive the contact piece to trigger different functions. At the same time, long press and short press the knob can also achieve different controls. The principle is that when the knob is in different positions or pressed, it will output a level signal and transmit it to the main control MCU. The main control MCU will process the level signal after receiving it, so as to complete the corresponding control. The operation is simple and easy, and the design of the rotary cap is rich and varied.

Description

technical field [0001] The invention relates to the technical field of electronic switches, in particular to a rotary switch and a control method thereof. Background technique [0002] Existing knob switches use tact switches or dome buttons to realize functions. One button usually corresponds to 1 to 2 functions. It also brings certain challenges to the appearance design of the product. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a rotary switch and its control method. The rotary knob can be rotated to different positions to trigger different functions, and the functions can also be realized by pressing the rotary knob, so that multiple functions can be concentrated in one Simple and easy operation on one knob. [0004] In order to achieve the above object, the present invention provides a rotary switch, comprising a PCB board, a dome, a first rotati...
