A device for suspending a payload from a support including a retraction assembly, an electrical connection component, and a payload connector assembly. The retraction assembly includes storage and output drum spools, and a constant torque spring on the storage drum applying torque at a constant level to the output drum. When opposite torque exceeding the constant level is applied to the output drum, the spools rotate and the spring unwinds from the storage drum onto the output drum. A cable is on another spool connected to the output drum spool so rotation of the output drum causes rotation of the cable spool. The cable attached to the payload connector assembly extends through an opening in the enclosure and an opening in the electrical connection component. When no additional downward force is applied to the cable, the electrical connection component is maintained so that power is provided to the payload.
