The induction light is actually an automatic switch control circuit, with various types. The methods of closing the switch (i.e. turning on the light) include "sound control", "trigger", "induction", "light control", etc. The opening method is basically the same, controlled by a delay circuit (automatically opening after working for a period of time). If you are interested, you can take a look at some introductions: press type, with a capacitor underneath, which is very thin and can cause changes in voltage and resistance when applied with force. It is called a voltage sensing capacitor, which is amplified by an amplification circuit to amplify the voltage change and connect the timing circuit and relay.
