1. The Rotary Switch itself has many uses. It can also replace some rotary pulse generators. It is mainly used in the front panel of the instrument and the man-machine interface of the audio-visual control panel. The Rotary Switch adopts a quadrature optical encoder, which replaces the pure digital device of the analog Potentiometer. It looks similar to traditional or resistive Potentiometers, but its internal structure is completely digital and uses optical technology.
2. The interior of the Rotary Switch is similar to the traditional incremental encoder. There are two orthogonal output signals, channel A and channel B, which can be directly connected to the encoder processing chip, and the switch has a cylindrical appearance. There are wiring terminals protruding "in the barrel" around them. These terminals are the extension of the static contact pieces "in the barrel". By analogy, each layer is insulated from each other.
3. In the composition of the Rotary Switch, a rotating shaft is formed by passing through the top cover from the bottom to form a rotating handle, and the bottom plate and the top cover are clamped up and down to form a switch assembly. When in use, it can be rotated 90 degrees, 180 degrees or 360 degrees. Each time it rotates to a position, the movable contact piece is connected to different static contact pieces, and different states can be output on the external terminals to realize control.
