SENSORswitches are capacitive pushbuttons which are activated without pressure, using a hand or other parts of the body. The buttons have a determinate sensing distance, which may be altered, however, by varying the approach speed and/or damping factor. A quickly approaching fi nger will achieve a higher sensing distance than a slowly approaching finger. A hand, with its larger damping surface, will achieve a greater sensing distance than a finger at the same speed. Sensitivity of the buttons is specified by the electronic circuit and cannot be changed serially. All sensors are checked for consistent sensitivity values, which have been determined by long-standing experience.
