<p>A touchless, digital electrical switch includes at least one sensor that is oriented or associated with other elements in such a way as to detect substantially vertical sweeping, or switching, motions. When an intended switching motion is sensed by the optical sensors within a predetermined period of time, loads are switched and the status of a switch is communicated to other switches, if any, along the same circuit (i.e., the "position" of the switch is changed). An indication of the "position" of the switch may be provided by way of a visual indicator. An acceptable switching motion may also result in an audible "click" or other signal.</p> |
