1. A switching device comprising:
a first terminal;
a second terminal;
a first transistor including a first end coupled to a first node and a second end coupled to the first terminal;
a second transistor including a first end coupled to a second node and a second end coupled to the second terminal;
a third transistor including a first end coupled to a third node to which a first voltage is supplied and a second end coupled to the first node;
a fourth transistor including a first end coupled to the third node and a second end coupled to the second node; and
a control circuit configured to control the first transistor, the second transistor, the third transistor, and the fourth transistor, wherein
the control circuit is configured to, when supply of the first voltage to the third node is stopped, turn the second transistor from an off state to an on state, turn the third transistor and the fourth transistor from an on state to an off state, and after a first period passes, turn the first transistor from an off state to an on state.
