ABSTRACT:
An electrically safe receptacle that in it's normal quiescent state will not have electrical current flow. Said electrically safe receptacle will be equipped with normally-open switches on one or both female conductors that are controlled by a strategically placed sensor to detect the insertion of a male plug. Detection of the male plug insertion will signal the normally open switches to close the circuit pathway and allow for the flow of electrical current to the device permitting normal operation. Insertion of a foreign conductive device such as a hair pin, knife blade, or metallic tool in one or both female conductors will fail to activate the sensor and thereby reduce or eliminate the possibility of accidental electrocution by preventing the flow of electrical current.
