Abstract
To reduce the number of signal lines for connecting an current detector and a solenoid electrically. Between solenoidsandand switches SW-and SW-and on the high sides with respect to the individual solenoids, respectively, there are connected current detectors-and-. The end portions of the solenoidsandon the individual GND sides are made common. The number of signal lines for connecting a controller and the two solenoids may be '2+1=3'. Therefore, the number of terminals (or the pin number) of a connectormay also be '2+1=3' (Pto P). The current detectors-and-detect the electric currents to flow to the solenoidsand. In the case of an incomplete grounding, for example, it is possible to detect an overcurrent to flow to the solenoids.
