Device for detection of presence of user's finger at proximity of detection zone of capacitive-effect sensitive touch device, has conductive surface connected to conductive track using spacer that ensures electrical connection with surface

摘要

The device has a support (7) including a conductive track (11) connected to an electronic circuit (4) used for measuring capacity variation. A conductive surface (3) is connected to the conductive track using a spacer (5), which is distinct from the conductive surface and the track, rests on the support, and is made of compressible conductive elastomer material. The spacer ensures electrical connection with the conductive surface while compensating height difference between an insulating body (2) of a sensitive touch device (1) and the support.
