CONSTITUTION:A remote-control 10 has semiconductor switches 13-1 to 13-4 such as terminal bi-directional thyristors for switching load connected to the terminals 10-1 to 10-4 of a branch circuit, and a mechanical switch Ra is inserted between a semiconductor switch group and the terminal 14 of the power supply of load. The switch Ra is operated interlocked with a changeover switch 11, closed when a needle Rb is brought into contact with a contact Rb-1, and opened when the needle is brought into contact with a contact Rb-2. Accordingly, a long lifetime can be kept even when load is switched frequently, the leakage of currents is reduced, and energy can be conserved.
