How to disconnect the car
Different devices to disconnect the battery for a long time and is successfully used by many car owners. Structurally, it is most often just a powerful switch that can withstand the current of hundreds of amperes. It is usually placed near the battery, forcing the owner of the car every time "dive" under the hood. At UAZ such switches are set at the factory, and you can manage them from the cabin. In some designs the circuit is removable "flag" - turns primitive "protivougonki."
Another group of master switch - electromagnetic, which are relays, designed for high current. They can be controlled from the cabin via a button on the instrument panel, which is much more convenient. The total lack of them, the presence of additional contacts for burning or oxidation which inevitably drop at start-up motor.
Do I need to disconnect switch at all? If the owner is not lazy each time to remove battery terminal before you leave home, then, of course, they would be useful. Will at least be no risk of fire at random closure of the wiring in the absence of the owner. Sometimes, the battery is quickly discharged through the circuit is live atignition is off.
For example, there are cases where this occurred through jammed gear motor faroochistitelya or light bulb, "glove", which are always lit as loose-fitting lid, or because of the mass, circular door limit switch, turn on the light in the cabin ...
On the other hand, in recent years the popularity of circuit weight has fallen markedly. This is due to the prevalence of electronic security systems, which can not operate when the power battery, and radio with digital tuning, immediately erased on power. Then the installation will have to pull the battery main switch a separate wire, and its meaning is lost in many settings, "self-discharge" through the radio or alarm is a constant one (albeit a small shock.)
