A retractable electric wall outlet assembly includes a housing with an electrical box capable of retraction or extension relative to the housing. A cam member coupled to a housing back plate includes rails which alternately define deep and shallow slots. A push-button plunger is coupled to the electrical box and extends into the housing. A ratchet is positioned for movement in the cam member, the ratchet and plunger having teeth configured to engage one another upon depression of the plunger. Depression of the plunger causes its teeth to engage and move corresponding ratchet teeth along respective rails from deep slots into adjacent shallow slots where they are retained, thus positioning the electrical box in a retracted configuration. A consecutive plunger depression causes the plunger teeth to engage and move respective ratchet teeth into adjacent deep slots where they are biased to move the electrical box to an extended configuration.
