Fused receptacle with power conversion/control board

Abstract

An electrical receptacle for use in a string of holiday lighting that has a removable, replaceable, on-board power control board. The control board taps into normal alternating current delivered to the receptacle from a pair of wires running from an electrical plug and uses it to deliver electrical power through a fuse to a third wire that supplies current to a set of lights carried by the third wire as it runs from the receptacle back to the plug. The control board may also rectify the current to the third wire so that the lights operate on direct current rather than alternating current. However the receptacle delivers alternating current to subsequent load plugged into it. The control board is also capable, with suitable choices of components carried by it, of other modifications of the electrical current it delivers to the third wire.
