Abstract
A bus switch for connecting and disconnecting a bus connection provided by a pair of buses includes a first switching element and a second switching element. The first switching element is coupled between an input terminal and an output terminal of a high-potential side bus of the pair of buses. The second switching element is coupled between an input terminal and an output terminal of a low-potential side bus of the pair of buses. The bus connection is connected when the first switching element and the second switching element are activated, and the bus connection is disconnected when the first switching element and the second switching element are deactivated.
