Abstract
A fan-heater appliance, e.g., hair drier, has a tapping arrangement for providing a variable supply to a fan motor to regulate the speed thereof. The tapping arrangement comprises a current collector which is slidable over a row of heads of tubular rivets which are attached to the coil tips of a linearly coiled resistance heating wire arranged transversely of the air flow path through the appliance. The current collector is operated by a crank arrangement including a knurled disc operator.
