1. Rotary switches have many uses. They can replace some rotating pulse generators, so this type of switch is almost always used in the front panel of the instrument and the human-machine interface of the audio-visual control panel. The rotary switch uses an orthogonal optical encoder as a pure digital device to replace the analog potentiometer. These rotary switches are similar to traditional or resistive potentiometers in appearance, but the internal structure of these rotary switches is completely digital and uses optical technology.
2. This switch is completely digital in its internal structure, not only using optical technology, but also using traditional incremental encoders. The two products are very similar, and there are two orthogonal output signals, namely channel A and channel B, which can be directly connected to the encoder processing chip. The appearance of this switch is cylindrical. The wiring terminals extending from the "tube" are distributed around. These terminals are extensions of the static contacts in the "tube". The static contacts are evenly distributed in the "tube" and insulated from each other.
3. Based on the above related content, we will continue to learn about the rotary switch. Each layer of its static contact piece is insulated from each other. A rotating shaft passes through the bottom cover to form a rotating handle. The bottom plate and the top cover are clamped up and down to form a switch assembly. When in use, there are 90 degrees, 180 degrees, and 360 degrees of rotation. Each time it rotates to a position, the moving contact piece connects to a different static contact piece, outputting different states on the external terminal to achieve control.
