Foot Switch Knob
The foot switch knob can use a rotary pulse generator that replaces the analog function of the traditional resistance potentiometer. These switches are usually used in the front panel of the instrument and the man-machine interface of the audio-visual control panel. The foot switch knob uses a quadrature optical encoder as a replacement for the analog potentiometer. Purely digital devices, these switches are similar in appearance to traditional or resistive potentiometers, but the internal structure of these rotary switches is completely digital and uses optical technology. 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.
