ABSTRACT:
A rotary switch with three controlling positions in a circulating sequence of "Off", a small output, and a large output, includes a cover and a base connected with the cover. A rotor which is made of an electrically insulating material and provided with three cam parts along its circumferential periphery, is mounted in the base to rotate an electrically conductive plate with two side portions engaged with two of the cam parts. A first, second and third leaf spring respectively has a fixed end connected with an input wire, an input end of a diode, and an output wire of the switch and a free end extending toward the rotor. The fixed end of the third leaf spring is also connected with an output end of the diode. When the switch is set to the "Off" position, the first leaf spring contacts with the rotor, and the other two leaf springs contact with the conductive plate via the two side portions thereof.
