A safety electrical outlet comprising a housing having at least one socket for receiving an electrical plug, the socket comprising at least two openings for receiving the prongs of a plug to be inserted therein, each of the openings having wipers associated therewith for making electrical contact with the prongs of the plug, a plunger associated with each of the openings and positioned behind the associated wiper so that when a plug is inserted into the opening, a prong depresses the plunger causing it to close a switch or contact set for supplying electric current to the wiper and the plug; plungers on both the hot and neutral sidesare in a series circuit in the current supply line so that a prong must be inserted into both openings to close both switches before current is supplied; the plungers are so positioned and configured that if a foreign object is inserted into the opening, it cannot make good physical contact with the plunger and will move off to one side of the plunger without depressing the plunger, so that such an object cannot cause current to be supplied to the wipers.
