发明名称 KEYBOARD MEMBRANE CIRCUIT
摘要 A plurality of switching points are connected in groups to respective terminal contact points via conductor strips on a keyboard printer circuit film. In order to achieve suppression of the coupling capacitances with simple means, decoupling resistor strips are printed between adjacent pairs of the conductor strips and are connected with the said conductor strips. The decoupling resistor strips consist of the same carbon resistor layer material as the terminal contact points.
