ABSTRACT:
A safe electrical receptacle has internal switches to connect the power source to female connector elements when plug blades are inserted through openings in the receptacle cover. A blade inserted through one opening closes the switch to energize the female element behind the other opening. Slidable switch operators are disposed between the receptacle housing cover and the female elements and are moved laterally to close the switches before the plug blades engage the female elements.
