ÔÇïWorking Principle:ÔÇïThis 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. 

The trigger port is used to connect the detected signal to realize related actions. ÔÇï ÔÇïFirst, we connect to the standing power supply 12V, and then if the trigger port (ACC) has power supply, the switch will be turned on. When the power supply of 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 open and this cycle can be done. ÔÇï ÔÇï

Note: The ground wire of the trigger signal of the trigger port should be connected with the negative pole of the power supply port (common ground). If the signal and power supply port are the same device or share the same power supply, they are already connected by default, and there is no need to find the signal ground wire and connect it to the negative pole of the power supply port.ÔÇïÔÇï ÔÇï

Delay time selection:ÔÇï The delay time is determined by the position of the red four digit dial switch. There will be different delay parameters corresponding to different positions, as shown in the table below:ÔÇï
