Claim 2:
3. The switch of claim 1, further comprising:
a second semiconductor rectifier element connected to a polarity terminal and the other polarity terminal of the DC power source to which the semiconductor rectifier element and the bypass electric circuit are connected;
a second bypass electric circuit that connects an input terminal and an output terminal of the second semiconductor rectifier element to bypass the second semiconductor rectifier element; and
a second breaker controlled by the control unit to open or close the second bypass electric circuit,
wherein the control unit controls the second semiconductor rectifier element to conduct a current, and controls the second breaker to close the second bypass electric circuit when the conduction signal is received, and further controls the semiconductor rectifier element to stop the conduction of the current when the second bypass electric circuit is closed by the second breaker.
