摘要: Provided is a relay unit that inexpensive and has long life, method for controlling circuit. A series circuit of mechanical switches connected in to load power supply, control selects one the as selected switch, performs switching timing shift, which constituted by at least first operation switch switched closed state after other than second open prior switch.
