Abstract
An electromagnetic contactor without arc generation wherein the silver contacts are omitted by providing contact portions between the fixed terminals and the movable piece to separate the semi-conductor completely from the power supply under open-circuit condition. In the contactor, the cylindrical holes are provided in each silver contact portion of the fixed terminals, the circumference of the holes being rounded to conform to the curvature radius of the contact portions which project from the conductive movable piece. The conductive pins wound by the coil springs are supported by the insulating plates to be isolated from the fixed terminals and also electrically connected via the subsidiary terminals to one terminal and a gate of a triac, respectively.
