Abstract: The pop-up electrical receptacle unit, when mounted in relation to an opening in a desk or table, enables the user to effect a retracted or concealed condition of the receptacle by pressing the receptacle downwardly and then permitting the receptacle to rise slightly by means of a coil spring. Such action rotates a ratchet mechanism into an obstructive relation with a pin carried on an actuator attached to the underside of the receptacle and movable therewith. The user effects a protracted or exposed condition of the receptacle by again depressing and releasing the receptacle so as to rotatively index the ratchet mechanism into an angular relation in which the actuated pin is no longer obstructed, the receptacle then being thrust upwardly by the coil spring into its protracted position in which position the prongs of an electrical plug can be inserted into the elevated receptacle.
