Contacting unit for an impedance limit switch

Abstract

A contacting device is provided for an impedance limit switch, the contacting device including: a printed circuit board having an electrically conductive contact surface; a radially disposed annular spring configured to establish electrical contact between the electrically conductive contact surface of the printed circuit board and at least one electrode of the impedance limit switch; and a non-conductive housing element. An impedance limit switch is also provided, including the contacting device; an electronic cup; and a measuring head configured to carry out a conductive and/or capacitive measurement and to record measurement data, the contacting device being configured to transmit the measurement data from the measuring head to the electronic cup via the contacting unit.
