Abstract
A switching device, for example a membrane switch, having an interconnect tail for electrically connecting the switching device to a circuit board. The tail has conductive traces formed thereon, which are in circuit with the conductive elements of the switching device. The conductive traces on the tail are raised from the plane of the tail thus making the traces the most prominent part of the tail. This structure assures electrical contact with the circuit board.
