What does 'power' mean on a car?

[StAustin]

In a car, 'power' refers to the engine start button. In English, 'power' means power supply, power output, or energy. The function of this button is equivalent to the key in ordinary cars. The normally open contact of the button connects to the engine starter motor control circuit, 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. When the button is released, the normally closed switch is engaged. The one-touch start device in a car is part of the intelligent car system, serving as a button device to simplify the ignition process, and it can also be used to turn off the engine. This device can be retrofitted at the original car key lock position or installed as an independent panel.
