<p>The arrangement has two sensor surfaces (101, 102) parallely arranged on an insulator, where one of the sensor surfaces is connected with a transition signal. The other sensor surface is temporally connected with an input (107) of a measuring amplifier (108). A pulse generator (103) generates the transition signal for switching of the former sensor surface that is alternately connected with supply voltage (Vcc) and earth (GND). The pulse generator has a selector switch controlling connection of the latter sensor surface between the input of the amplifier and the earth. An independent claim is also included for a method for operating a switching arrangement.</p> |
