Abstract
PURPOSE: To prevent the coil of an auxiliary contactor from burning, by providing a resistor in a circuit containing the auxiliary contactor.
CONSTITUTION: A third switdh 20, which is a contact (a) of the auxiliary contactor 10, is provided between a switch 1 and a first switch 4. The resistor 21 is coupled in parallel with the third switch 20 between the switch 1 and the first switch 4. Since the current flowing through the auxiliary contactor 10 is restricted by the resistor 21, the coil of the auxiliary conactor 10 is prevented from burning.
