<p>An arcless contactor is prepared, without any silver contact point, not to generate arcs when breaking the contactor. Circular holes (4,4') are punched at the conventional silver contact points of fixed members (2,2'). The circumference of each hole is chamferred to be fitted to the curvature of protrudent contact points of a conductive moving member (1). A conductive pin (5) having a coil spring (6) and an aux. port (8) is mounted on an insulation board (7) to be normally in an open circuit. The aux. port of the pin is communicated to the port (T2) and the gate (G) of a triac (T).</p> |
