Abstract
A dimmer switch adapted to be connected in-line with an electrical power cord for selectively varying the power applied by the cord to an electric load, such as an electric lamp or the like. The dimmer switch includes a housing containing a dimming circuit and stab-type terminals for piercing the insulation on a power cord in order to make electrical contact between the power cord's wire conductors and-the dimming circuit. According to the invention, the dimmer switch housing is adapted to receive power cords of different sizes, e.g. SPT-1 and SPT-2, and apparatus is provided for reliably connecting the wire conductors of a received power cord to the stab terminals of the dimming circuit regardless of the power cord size.
