Abstract
On-vehicle electrical loads () are connected to an on-vehicle battery () via a series circuit including a load switching element () and a reverse current interrupting element () for a load circuit, and a feeding switching element (A) that is closed in response to closure of a power supply switch (). The element (FET) () is closed when the switch () is closed and a power supply voltage is applied to a load power supply terminal (Vba) connected to the element (A), to thereby be energized in an energization direction of an internal parasitic diode thereof. The element () is de-energized when the switch () is opened. Thus, malfunction is prevented, which occurs when the element (A) is opened, a short-to-power flows backward via the element () into the terminal (Vba) so as to feed power to another device connected to the element ().
