PURPOSE: A load switch with three positions is provided to improve workability by arranging components of an input side and a ground side to be symmetrical. CONSTITUTION: A crank handle(11) is combined with an inter-working unit of an input side and an inter-working unit of a ground side while being combined with a principal axis(10). The crank handle transfers torque of a ground shaft(30) and an input shaft(20) to the principal axis. An elastic member(90) is combined with the inter-working unit of the input side and an inter-working unit of the ground side. The elastic member generates torque for rotating the principal axis to an input position or a ground position. The inter-working unit of the input side and an inter-working unit of the ground side are formed to be symmetrical.
