Current transformer for load switch
 A current transformer for a load switch which has an interior construction tightly engaged with a main bushing therein, allows a voltage in a cable to be detected by forming an engaging hole, communicated with a conductive socket of the main bushing, on a portion of an outer circumferential surface thereof, and which has a current transformer coating casing, made of a rubber material, for thereby diminishing a thickness of the current transformer, includes a core in a ring shape, a coil winding the core, a rubber coating member for tightly covering the core and the coil therein, and coil terminals connected to both ends of the coil. The rubber coating member includes a lower coating part for tightly covering a base unit of the main bushing, and an upper coating part for tightly covering a jaw unit of the main bushing, as well as the coil and the core.
