Abstract:
1. A smart switch comprising: a magnetic operator; at least one magnetic sensor located to sense relative movement between the magnetic operator and the at least one magnetic sensor; and, a processor arranged to process an output of the at least one magnetic sensor so as to detect whether the magnetic operator has entered at least one of a first over travel range, a second over travel range, and a normal operating range, wherein the first over travel range is a left over travel range and the second over travel range is a right over travel range and wherein the processor is arranged to process the output so that the output has a substantially flat left over travel voltage versus position range, a substantially flat right over travel voltage versus position range, and a sloped normal operating voltage versus position range between the substantially flat left over travel voltage versus position range and the substantially flat right over travel voltage versus position range.
