    • A load side terminal connected to a load portion, a power source side terminal connected to a power source portion and a sacrifice electric pole connected to the power source side terminal are fixed to an apparatus main body. A movable plug is provided movably to the apparatus main body. The sacrifice electrode is constituted by a sacrifice electric pole with resistor connected to the power source side terminal via a resistor and a through sacrifice electric pole directly connected to the power source side terminal and arranged to shift from each other such that in a procedure of moving a conductive portion of the movable plug from a circuit opened position to a circuit closed position. The conductive portion is firstly brought into contact with the load side terminal, successively brought into contact with the sacrifice electric pole and finally brought into contact with the power source side terminal.
    • 连接到负载部分的负载侧端子,连接到电源部分的电源侧端子和连接到电源侧端子的牺牲电极被固定到设备主体。 活动插头可移动地设置在装置主体上。 牺牲电极由具有通过电阻器连接到电源侧端子的电阻器的牺牲电极和直接连接到电源侧端子的直通牺牲电极构成,并且被布置成在移动的过程中彼此偏移 可动插头的导电部分从电路打开位置到电路闭合位置。 导电部分首先与负载侧端子接触,依次与牺牲电极接触,最后与电源侧端子接触。
