Abstract
A thermal hair styling appliance includes interchangeable attachments, such as hair retaining clips, comb-brush clips or other types of attachments which are selectively attached to an operating button that is pivoted on a handle of the appliance. The appliance further includes a main electric heater which is controlled by a thermostat which, in turn, responds to a pair of auxiliary heaters. By selectively energizing the auxiliary heaters, the temperature of the main heater is controlled. A versatile hair styling appliance is thus provided. According to one embodiment, the operating button includes at least one projection which engages a slot in the end of the attachment being used. The attachment is held within the button by detents which engage other slots in the end of the attachment.
