Abstract

Abstract A hair dryer includes a hand grip with a push switch for energizing the electrical components of the dryer. The components are turned on by depression of the push switch when the grip is held by the user and are automatically turned off when the user releases the grip. A holder with an insertion socket carried by an angularly adjustable neck is provided for supporting the dryer by insertion of the hand grip into the socket. The socket includes a wall perforated by a slot. The user may insert the hand grip into the socket with the switch aligned with the slot so that the switch is not depressed and the components are not energized. Alternatively the grip may be inserted with the switch unaligned with the slot so that the switch is depressed by the socket wall to energize the components.
