Mechanisms for providing electrical controls on a rotating assembly such
as a cable winding device are disclosed. The cable winding device generally includes
an electronic control actuator such as a keycap attached to a housing and providing
an actuating pad actuatable via an opening provided in the housing, the housing
containing a spool, a circuit component including an electronic control such as
a switch actuatable via the actuating pad, and a rotational actuator interface
such as a skid pad located over the electronic control to interface between the
actuator pad and the electronic control at all rotational orientations of the switch
relative to the actuating pad and/or even while the spool is rotating. The circuit
component and the skid pad are configured to rotate with the spool relative to
the housing. The switch is disposed off of an axis of rotation and may be, for
example, an answer/end, on/off, mute, volume, play/stop, rewind/fast forward, and/or
enter/accept control. The cable winding apparatus may be incorporated in a headset system.
