Abstract
Disclosed herein is a safety outlet which may be readily interchanged for a standard electrical outlet and which has a unique safety feature for preventing insertion of a foreign object into one of the slots in the outlet thereby preventing electrical shock. This safety feature is obtained at low cost and is particularly suited for high speed assembly. The safety also provides improved plug/prong engagement.
