A collapsible cordless electric hair curling appliance includes a hollow handle adapted for grasping by a user. A heating wand is extensibly slidably retained in the hollow portion of the handle. An improved positive temperature coefficient heating element assembly is positioned inside the wand. An electric plug assembly is also slidably mounted in the hollow portion of the handle. The plug is mounted so as to extend from the handle for connection with a conventional electric socket only when the wand is substantially fully inserted into the hollow handle. The novel plug assembly eliminates the need for a conventional electric cord and is also rotatably mounted in the handle to provide added convenience for plugging the appliance into a conventional electric socket. For storage, both the wand and plug assembly may be enclosed within the handle. The electric circuit for heating the wand is closed only when both the wand is fully inserted in the handle and the plug assembly is fully extended therefrom to provide added safety features to the appliance.

A motor-driven electric shaver operable over a wide range of alternating line voltages includes a capacitor for supplying unidirectional current to the motor. The capacitor is periodically charged through a current switching device serially located between the line and the capacitor. The switching device is rendered conductive only when the instantaneous voltage level of the applied line current is less than a predetermined level such that the average voltage developed across the capacitor and applied to the motor corresponds to the nominal requirements of the motor. Since the switching device is operated in either a saturated or nonsaturated state, power dissipation within the shaver is minimized.
