<p>PURPOSE:To reduce the jointing section as much as possible and to improve the reliability of a switch by providing a moving rod in a moving side contact section into a hollow section of a conductor in a charging section and by switchingly operating the moving rod in the combination of an insulating operation bar, a pinion and a rack. CONSTITUTION:When a connecting rod 10 is rotatingly driven by an unillustrated operation device, this rotating driving force is axially converted by a gear box 7 to drive a shaft 8 in rotation. Since an insulating operation bar 6 jointed to this shaft 8 is engaged with a rack 4 provided to a moving rod 1 through a pinion 5, the moving rod 1 moves in the direction of a right angle with the insulating operation bar 6 and comes into contact with a fixed side contact section 11 to cause a closed state. If the rotating direction of a driving shaft is driven opposite to the closing movement, an opening movement will be performed. The reliability of an equipment on a movement characteristic can remarkably be improved as the jointing section to transmit the driving force is sharply reduced.</p> |
