Abstract
To perform a forcible disconnection when voltage outside a reference range is applied to a terminal, provided is a switching apparatus comprising a main switch provided between a first terminal and a second terminal; a voltage detection section that detects whether voltage of the second terminal is within a reference range; and a control section that controls the main switch according to a control signal received from a control terminal and turns OFF the main switch when the voltage of the second terminal is outside the reference range. The voltage detection section includes a detection switch that disconnects the second terminal and the control section from each other when the voltage of the second terminal is within the reference range and connects the second terminal and the control section to each other when the voltage of the second terminal is outside the reference range.
