Abstract
A hair dryer including more than one switch to control air flow rate and/or temperature. The switches are located on different portions of the hair dryer, allowing the user to select air flow rate and/or temperature when gripping the dryer in different ways. In one aspect, a switch is mounted like a trigger on a pistol-shaped hair dryer. A collar located entirely around the hair dryer's barrel mechanically links this trigger switch to a lever positioned on the barrel. When the lever on the barrel is squeezed or pulled, the collar rotates around a pivot to activate the trigger. This collar arrangement thus provides a second switch to control the air flow rate and/or temperature of the dryer.
