The switch (300) has an integrated semiconductor circuit component (IC1) including monitoring circuit for detecting short-circuit, and a memory for storing detection results. A capacitor (C1) is integrated between an operating voltage connection (VCC) of the semiconductor circuit component and a ground connection or control signal input (IN/GND) of the semiconductor circuit component. A transistor (T31), a diode and a resistor draw potential of the ground connection to value below ground potential during breakage of operating voltage (Ub) at the operating voltage connection. An independent claim is also included for a motor vehicle power supply system comprising a current source. |
