What does 'power' mean on a car?

[VanGianna]

In a car, 'power' refers to the engine start button. In English, 'power' means power supply, power output, or energy. The function of the 'power' button in a car is equivalent to the key in a conventional car. The normally open contact of the button connects to the control circuit of the engine's starter motor, while the normally closed contact connects to the car's main power supply. To start the engine, simply press the start button, and the starter will activate. Releasing the button will close the switch. The one-touch start system in a car is part of the smart car features, serving as a button device that simplifies the ignition process and can also be used to turn off the engine. This device can be installed in place of the original key lock or as an independent panel modification. Most car 'power' modifications are carried out by anti-theft device manufacturers. With increasing market demand, one-touch start has gradually become a standard feature in cars, and product prices have also decreased, making it more accessible to the general public. Professional installers are required to modify the system and ensure its proper functioning. The one-touch start system involves car electronic anti-theft measures and requires special handling.
