摘要： A manually activated position indicator with electrical output signals includes a plurality of adjacent electrodes (S, Al-, Al+, Bl-, Bl+, Ax-, Ax+, Bx-, Bx+,Ay-, Ay+, By-, By+), which are electrically insulated from one another and are covered on one side by an electrically insulating layer (3) the side of which opposite said electrodes is provided as a support surface for a finger (4) of the user of said position indicator wherein said electrodes form at least three groups, and all of the electrodes (S) of a first group are connected to a voltage source (5) that delivers an alternating voltage (Us). The electrodes of the other groups are connected to a signal evaluating circuit, and at least one electrode of said other groups is arranged adjacent to an electrode (S) of the first group.
