DEVICE FOR OPERATING SWITCH

摘要

This invention is concerned with the manipulation device of switch to manipulate such switch as a breaker and a contactor. The device has functions like manual manipulation and remote control manipulation simultaneously. The cut off operation of the vacuum switching tube (1) is performed as follows. Firstly, the crank pin (10) is oerated and through the lever (9) the main axis (5) is rotated. The driving rod (2) is operated through the lever (6) fixed the main axis, contact pressure spring (4) and the insulating rod (3). Finally the vacuum switching tube is switched. Futhermore the crank window plays a role to hold sufficient space as well as to stop the position of closed loop.
