Abstract
The present invention incorporates a system for varying the output signal and regulating the power consumed by an electrical device. It achieves its purpose by moving a magnet relative to a Hall effect sensor which is responsive to an intersecting magnetic field. The Hall effect sensor creates an electrical output signal which determines the input signal of an output element of the device. The electrical Hall effect sensor signal thereby controls the output signal emitted by the electrical output element. The magnet is moved using a movable element. Since the location and movement of the magnet regulates the Hall effect sensor output signal, the output signal of the electrical device as well as its rate of change are regulated using the movable element. In order to conserve power the Hall effect sensor element is usually not energized when the device is in the 'off' mode. However a switching means correlated with the position of the movable element energizes the Hall effect sensor when the magnet has created a magnetic field of acceptable density and direction.
