Abstract
Electric control apparatus (20) for equipment (1) comprising a driving circuit (5) for generating a signal (S.sub.1) to drive the equipment as installed in a vehicle, the driving circuit including circuitry having a first specified working voltage range, and a breaking circuit (6) operatively interposed between the driving circuit and the equipment, the breaking circuit including a first switching circuit (100) for operatively interrupting the supply of the drive signal to the equipment under a condition that the supply voltage (Vdd) is lowered below a first predetermined level (V.sub.1) set lower than a normal level with respect to the first working voltage range, the first switching circuit including circuitry having a second specified working voltage range not exceeding the upper limit of the first working voltage range, wherein the breaking circuit further includes a second switching circuit (10) operatively interposed between the first switching circuit and the equipment, the second switching circuit operatively interrupting the supply of the drive signal to the equipment under a condition that the supply voltage is lowered below a second predetermined level (V.sub.2) set lower than the first predetermined level and higher than the lower limit of the second working voltage range.
