CONTACT STRUCTURE FOR SLIDACS TYPE AUTOMATIC VOLTAGE CONTROL APPARATUS USING BEARING

PURPOSE: A contact structure is provided to achieve an improved response speed of output voltage by reducing mechanical friction between the input contact surface and output line. CONSTITUTION: A contact structure comprises a bearing unit(4) for reducing mechanical friction with the contact portion of a slidacs(3); a DC motor(2) for rotating the bearing unit in forward and rearward directions; an output line(5) connected to a shaft(9) which serves as a connector between the bearing and motor, and a common line(1) as a center and reference line of the input/output voltage; escape prevention films(8,7) attached to the slidacs. Since the bearing used as a contact material, mechanical friction between the input contact surface and output line is decreased, to thereby improve response speed and obtain superior characteristics.
