PURPOSE:To reduce the cost of a hybrid circuit and to decrease the man-hours at the time of assembly by connecting the input circuit of a control circuit to the middle of a load driving circuit and operating the driving circuit and control circuit with the switch of the load driving circuit. CONSTITUTION:The hybrid circuit for load driving consists of a load 1 and its driving circuit 2, the control circuit 3 and its input circuit 4, and the switch S and a variable resistance VR. This variable resistance VR is operated associatively with the switch S, which is turned on to supply a necessary current from a power source to the driving circuit 2 for the load 1 through the variable resistance VR. At the same time, the input circuit 4 of the control circuit 3 is closed to put other equipments in operation through its output circuit 7. Consequently, the load driving circuit 2 and the input circuit 4 of the control circuit 3 are put in operation by operating the one switch S.
