12V Universal Start-Stop Switch Car One-Key Start Button

1. Utilizing high-performance silicone, the key press cycle exceeds 50000 times
2. 3D simulation design and precise mold manufacturing ensure that the keys do not get stuck and the pressing and discharging process is smooth
3. 4 high-conductivity coating contact switches ensure precise conduction each time the key is pressed
4. The circuit board pads use gold plating technology, resulting in lower contact resistance and higher conduction rate for the switches
5. 3P line function description: + Positive trigger output control. After pressing the start button, the yellow line outputs +12V power; the black line connects to the negative output line for the key switch control, and the key switch light will light up
