The Ignition Switch Is Suitable For Electrical Circuits
- Oct 17, 2017 -

Ignition switch is mainly used to connect and cut off the ignition circuit, but also control the starting circuit, generator excitation circuit, instrument circuit and other auxiliary electrical equipment circuit, is an important car control circuit switch.

Ignition switch function:

The ignition switch is generally equipped with 0 or LOCK, I or ACC, II or ON, III or START four positions.

The ignition switch goes to the III or START position and the starter starts. Ignition switch to I or ACC position, the engine is turned off, Ignition Switch other vehicles can be used normally.

Ignition switch to II or ON position, the engine is working.

The ignition switch goes to 0 or LOCK position, the engine turns off, and the steering wheel is locked when the key is pulled out.

Ignition switch: the ignition system switch (usually use the key), Ignition Switch can be free to open or close the main circuit of the ignition coil, also applies to other electrical circuits.

Ignition switch type: gas lighters, gas stoves, gas water heater ignition switch; car, motorcycle start and ignition switch; launch missiles, satellites, Ignition Switch all kinds of spacecraft ignition switch.

Common ignition switch ignition method: ignition methods are mainly piezoelectric ceramic ignition and power coil ignition.

Ignition switch stalls:


LOCK locked car, the general car keys into this stall is equivalent to lock the steering wheel, Ignition Switch the steering wheel can not have too much activity.


ACC to the whole car power, radio, lights, etc. can be used normally, can not use air conditioning.


ON In addition to the starter, the rest of the basic equipment are open, you can unlock the steering wheel, you can use air conditioning, but the air conditioning cooling effect is not very good. Ignition Switch Normal driving when the key is in the state, when the whole car all the circuits are in working condition.


START start the car, start the engine, fuel consumption, start the car, air conditioning cooling effect will become better. START file is the engine start gear, after the start will automatically return to normal state is ON file.
