Working principle:
This switch is a power off delay shutdown function. The power supply of the 12V power supply port is a standing power supply, which can generally be connected to a battery or other adapter power supply. Trigger ports are used to connect detected signals to perform related actions.
First we connect the 12V standing power supply, then if the trigger port (ACC) has power, the switch will turn on. When the power to the trigger port is disconnected, the module will automatically turn off the relay after a delay for a period of time; if there is voltage, the relay will turn on, and the cycle can be completed.
Note: The ground wire of the trigger signal of the trigger port should be connected to the negative terminal (common ground) of the power port. If the signal and power ports are the same device or share the same power supply, they are already connected by default, and there is no need to connect the signal ground wire to the negative pole of the power port.

Application:
1. Household switch control--exhaust fans, cooling equipment and other household products;
2. Automotive electronic control - power-off delay control of automotive circuits such as navigation, media sound effects, and door and window delay lifts;
3. Industrial equipment control - access control equipment control - warehouse, aisle lighting;
4. The lights and headlights are turned off after a delay.
