A cable retracting device including a housing with an interior space bounded in part by a side wall. A spindle projects into the interior space from the side wall and rotatably supports a spindle. A number of electrically conductive rings are affixed to the side wall and are concentrically arranged around the spindle. A number of electrical leads are connected to the rings and extend outwardly from the housing. A number of electrical contacts protrude from one side of the spool. Each of the contacts slidably engages a respective one of the rings. Another number of electrical leads is wound about the spool, each of which is also connected at one end thereof to a respective one of the electrical contacts. The leads wound on the spool have another end extending from the housing that can be selectively pulled from the spool. A coiled spring connected to the spool rewinds the leads on the spool in the event that they become unwound.
