ABSTRACT:
A hair curling device is made up of one or more heating units which may be plugged into a handle and into each other to make up a heating surface of a selected length. A set of electrodes in the heating units are configured so that a voltage provided by the handle is impressed across a heating resistance within the heating units. Each additional heating unit, when plugged into the handle or a previously installed heating unit, changes the electrode configuration so that the heating current is routed into each new heating unit. A current limiting device is provided so that the temperature of the device is selectable. Heating units of various diameter are provided so that loose or tight curling is made possible by the simple expedient of snapping a different set of heating units into the handle.
