  • Asymmetric mechanical shunt switch for use in a socket of a string of lights
    Patent number: 7557497
    Abstract: An asymmetrical shunt switch for use in a socket of a string of lights resides in an otherwise typical lamp of a string of lights. The present switch is a shaped spring held in position between the two conducting terminals by a holder so that both of its lateral sides contact the terminals when the base is removed. When the base is inserted, a depending prong on the bottom corner of the base presses one side of the shaped spring away from its terminal and thereby allows current to flow through the Dumet wires to the filament.
