MACHANICALLY OPERABLE ELECTRICAL DEVICE

摘要

Mechanically Operable Electrical Device A mechanically operable electrical device (102), comprising a transmitter electrode (302), a receiver electrode (312) and a moveable conductive element (201). The device is configured such that the conductive element is moveable to a first position remote from said electrodes such that the transmitter electrode is capacitance coupled to said receiver electrode, and the conductive element is moveable to a second position closer to the electrodes such that the capacitance coupling is reduced.
