ABSTRACT:
There is disclosed herein a safety outlet having means which prevent the insertion of objects other than an electrical plug which may engage an electrical contact within the outlet thereby eliminating the hazard of accidental shock. The safety outlet comprises a sliding member housed within a cap member which prevents access to the electrical contacts unless actuated by means of the prongs of an electrical plug. Latching means may also be provided to further insure against actuation by objects other than the prongs of an electrical plug. Additionally, means for preventing the withdrawal of the plug without first returning the outlet to a safe position may be incorporated herein. The safety outlet of the present invention is adapted for any form of electrical connection, including conventional wall outlets and extension cord connectors.
