| 摘要 |
The capacitive contact switch (10) comprises sensor surfaces (12,22) as part of a capacitive sensor unit, whose capacity changes during contact. The contact switch has an auxiliary electrode (24), which is arranged near measuring electrode (20) on printed circuit board (18), from which the measuring electrode is electrically isolated and lies on another potential different from the former potential. An independent claim is also included for a switching configuration for a capacitive contact switch, which has a contact switch comprising a sensor circuit and an evaluation circuit. |
