What is the rotation 2 step push button switch?

A rotating 2 step push button switch can be used to replace the rotary pulse generator that mimics the function of traditional resistance potentiometers. These rotating 2 step push button switches are generally used in the front panel of the instrument and the man-machine interface of the audio-visual control panel. The rotary buttons are orthogonal. Optical encoders are used as pure digital devices instead of imitating potentiometers. These rotary 2 step push button switches are similar in appearance to traditional or resistive potentiometers, but the internal structure of these rotary buttons is completely digital and uses optical skills. Similar to traditional incremental encoder products, there are two quadrature output signals (channel A and channel B), which can be directly connected to the encoder processing chip.
