Capacitive proximity and/or contact switch avec floating electrode

摘要

A capacitive proximity and/or contact switch (10) comprises a cover plate (12) having an upper side (14) and an underside (16), wherein the upper side (14) provides a sensitive area (18) of the switch and the cover plate (12) at least in the region of the sensitive area (18) is at least partially non-conductive; and a conductive sensor face (28) being disposed at a distance from the underside (16) of the cover plate (12). The dielectric system (36) of this capacitive proximity and/or contact switch (10) comprises the cover plate (12), at least one non-conductive element (22, 30) facing towards the sensor face (28) and at least one conductive element (32) arranged between the cover plate (12) and the non-conductive element (22, 30).
