Document Type and Number:
Japanese Patent JP3574367
Kind Code:
B2
Abstract:
This invention has as an object to provide an operating apparatus for an electric power load break switch which seeks increases in the efficiency of force transmission and decreases in size. Its constitution is one in which rotational movement from a drive shaft of a drive mechanism is transmitted as rotational movement to an operating member secured to an output shaft through an input spur gear, a cylindrical roller, a rotating lever, etc., without being converted to linear movement.
