When the conductor slide 5 moves from the conductor material portion to the insulation material portion, the circuit between the incoming line end 3 and the outgoing line end 4 is cut off and is no longer conductive. In order to maintain the directional movement of the conducting slider 5 between the first guide plate 1 and the second guide plate 2, the guide edges 103 may extend downwards from both sides of the first guide plate, the guide edges 203 may extend upwards from the second guide plate 2, and the conducting slider 5 is directionally moved under the guidance of the guide edges 103 and 203.
