ABSTRACT:
In one form of the present preferred embodiment of the present invention it relates to a three-position feed-thru electric line or wire cord piercing switching combination of the rotary type which at least saves electric energy by use of a half-wave diode rectifying means. The electric energy saving, three-position, combination switch having one "off" and two electrical passing switching positions. The switch will provide three-positions of 120 degrees for each position so that machine-gun or gunning, overshooting or rapid manual switch actuation for each of the three-positions is substantially prevented and also provides an electrical "off" half-wave rectified "dim" and an electrical full-wave "on" illumination to a single filament lamp, string of Christmas tree lamps and the like, and will even provide at least eight separate combination, of three illuminations, when electrically connected ahead of a, for example, conventional LEVITON rotary 3-way lamp socket switching means which uses a conventional 3-way incandescent lamp member which is removable inserted into the lamp socket portion thereof. The half-wave diode rectifying means is electrically connected to and substantially shuntingly between two of three electrical contact members of the conductor wire-piercing and the wire non-piercing type of switch.
