The present invention relates to a power transmission apparatus of a load switch for processing and, more specifically, to a power transmission apparatus of a load switch for processing which has a simple structure and reduces an occupying space and weight by transmitting power to each phase in a lump by including an intermediate coupling part which uses a single cam. The power transmission apparatus of a load switch for processing according to an embodiment of the present invention transmits driving force of an operation device to a main circuit switch by being installed between the main circuit switch for opening and closing a main circuit and the operation device for inputting the main circuit switch or operating toward an opening position. The present invention includes: a base plate which is combined with the lower part of the housing of the main circuit switch; a main shaft which is combined in a state of being separated from the base plate in parallel by a mounting bracket; the intermediate coupling part which rotates the main shaft by receiving driving force which is transmitted from the operation device; and a contact spring unit which transmits the rotary force of the main shaft to the main circuit switch. |
