Abstract
A control dial features a disk-shaped handle with a diametrical pivot, permitting pivoting of the handle from a first orientation flush with the surface of the controlled device to a second position perpendicular to the surface of the controlled device. In the second position, rotation of the handle carries with it a generally hemispherical housing in which the hinge or pivot is mounted. The housing, in turn, is mounted for rotation about an axis perpendicular to the surface of the controlled device, and is connected to a rotary switch which may be mounted on a printed circuit board fixed inside the controlled device.
