Abstract
PURPOSE:To enable the unlighting and the stopping of engine from the outside of a car, by providing an out-of-car switch on the out-of-car door or other panel while constructing the control circuit with PNP transistor such that the in-the- car switch, ignition switch, etc. can be controlled. CONSTITUTION:Upon closing of the out-of-car switch SW2, a pulse signal is applied through a one shot multi-vibrator 2 to a NPN transistor Tr2. When said pulse signal is high, the base current will flow through the transistor Tr2 to turn on the transistor while to turn off the thyristor SCR. When it is low, the transistor Tr2 is turned off. When SW1 is closed and the transistor Tr2 is conducting, the ON-OFF of the transistors Tr1, Tr2 are synchronized. Consequently the power supply to the load 1 is interrupted. The capacitors C1, C2 are charged through the switches SW2, SW1 and discharged when opening. Consequently the electrical system can be stopped through the out-of-car operation.
