PURPOSE:To assure comfortableness through a controller which turns off the switch of the air conditioner of an automobile when it is accelerated over a prescribed level, by automatically putting the air conditioner into operation when a prescribed time has elapsed since the turn-off of the switch. CONSTITUTION:When an automobile is started by sharp acceleration, a mercury switch 8 closes in response to the starting so that a capacitor 9 is quickly carged and the level of an input terminal of a NAND circuit 18 becomes high. The outut of the NAND circuit 18 is high for a time which lasts since the turn- on a main switch 5 and is set by a time constant circuit 22 comprising a resistor 14 and a capacitor 15. For that reason, the outputs of NAND circits 22, 28, 29 are low, high and high respectively, a transistor 30 is turned off and an electromagnetic clutch is energized to drive the air conditioner of the automobile. At the end of the set time, the output of the NAND circuit 18 becomes low. Then transistor 30 is then ketp on for a time set by a time constant circuit comprising a capacitor 24 and a resistor 23, to stop the air conditioner. |
