DISPOSITIVO PER VARIARE LA RESISTENZA DI CIRCUITI ELETTRICI E LA CON DUZIONE DI CORRENTE IN CIRCUITI ELETTRICI |
摘要 |
<p>A device forming a potentiometer for varying the resistance of an electrical circuit, and a switch for changing the state of current conduction in the circuit. The switch has a casing fastened to the potentiometer, and the potentiometer has a casing and a plate joined together. The device has a rotatable component having a central protuberance extending through the plate. A first discoidal element is carried by the rotatable component and has a metallic cursor. A resistance track and a metallic collector are stationarily mounted on the plate. The cursor is continuously and simultaneously in contact with the resistance track and the collector. A second discoidal element is mounted in the switch casing for engagement by the protuberance and is releasably coupled to the rotatable component when the switch is coupled to the potentiometer. A fixed contact is mounted on the switch casing and a movable contactor arm is movable mounted on the switch casing.</p> |
