Encoder Switch

A rotary encoder switch is an electronic component that, through the operation of a knob, alters contact states or photoelectric signals to generate pulses, thereby enabling function switching.
The operating principle of a rotary encoder switch involves mechanical contact, photoelectric conversion, and pulse signal generation; the photoelectric sensor typically consists of a light-emitting diode (LED) and a photoresistor.
Rotary encoder switches are widely utilized in fields such as smart grids, rail transit, industrial control, the Internet of Things (IoT), medical equipment, automotive systems, and various other consumer electronics.
