In a switch circuit for use in a vehicle, conduction between a drain electrode and a gate electrode of each of a first main transistor and a second main transistor is switched on or off depending on a voltage between the gate electrode and a source electrode. A first surge protection device is connected between the drain electrodes of the first main transistor and the second main transistor. The first surge protection device keeps a voltage that is applied to the first surge protection device at a first predetermined voltage or lower. A sub transistor is provided between the gate electrodes and the source electrodes of the first main transistor and the second main transistor. The sub transistor is turned on when the first main transistor and the second main transistor are turned off.
