PROBLEM TO BE SOLVED: To decrease signal emission during switching period in order to lessen impact on other circuits, and to stabilize a signal source. SOLUTION: The switching circuit comprises a signal source 1 and a switching means 2 for connecting the signal source 1 to a first load circuit 3 or a second load circuit 4. A radiant quantity attenuating means 5 is arranged between the signal source 1 and the switching means 2. The radiant quantity attenuating means 5 attenuates a signal emitted from the switching means 2 at least during a period from separation of the signal source 1 from either of the first load circuit 3 or the second load circuit 4 to connection to the other, in order to decrease the level of a signal hopping to other circuits.
