ABSTRACT:
A dual temperature electric hair curling iron has a barrel rotatable relative to a rigid handle by means of a friction clutch therebetween. The barrel includes a plurality of apertures allowing steam or mist generated within the barrel to flow into contact with the hair being curled. An electric heater in the barrel is controlled by a low limit (220.degree. F.) thermostat and a high limit (270.degree. F.) thermostat located within the barrel. A normally open momentary contact switch manually operated by a ring-like arm encompassing the a front portion of the handle is arranged in circuit with the thermostats and heater in such a manner that the low limit thermostat controls the temperature of the barrel when the switch is in its normal open position. Closing of the switch by movement of the arm relative to the handle disables the low limit thermostat and allows the barrel temperature to increase to the limit set by the high limit thermostat thereby allowing tighter curls to be produced. The arm is spring-biased so that the switch is automatically returned to the normally open position when the arm is released, thus providing fail-safe operation of the iron under control of the low limit thermostat.
