Abstract
A shutter assembly for a receptacle. The shutter assembly may include a first plate, a second plate disposed adjacent the first plate, a shutter disposed between the first plate and the second plate, a first spring that provides lateral movement of the shutter, a second spring that provides transverse movement of the shutter and a plunger for providing a pivot point to the shutter. The plunger may be disposed between the second spring and the shutter. According to an embodiment of the invention, when there are no pins or there is one pin inserted into the shutter assembly, the shutter is in a first position and lugs on the shutter abut locks disposed on the first plate and the second plate, thereby barring access to apertures in the assembly. When two pins, other than the ground pin, either sharp or round edges, are inserted into the shutter assembly, the shutter slides laterally to expose apertures in the assembly, making the receptacle available for use.
