ABSTRACT:
A remote control includes at least one spring motion switch and an electrical circuit to control remote control functions when the remote control is moved. In one embodiment, the motion switch activates keyboard back-lighting. A single spring motion switch may be used or two spring motion switches may be positioned approximately orthogonally, for example, a first spring motion switch to activate on motion along the remote control's length L, and a second spring motion switch to activate on motion along the remote control's width W. One simple and inexpensive motion switch is a cantilevered spring. The remote control according to the present invention with back-lighting activated by remote control motion is particularly useful when viewing a video or listening to music in low light.
