Digitaler Orgeloszillator, Teil 2

An important alternative to the mechan- ical switch - rotating or push-button - is the touch switch. This has the advan- tages of greater reliability and a higher switching speed, as well as being noise- less and not subject to wear. Furthermore, front panels with touch contacts can be made available as printed circuits, so that it becomes much easier to build equipment with a neat appearance. Elektor laboratories have been asked to design a touch control switch with a single touching point and costing no more than its mechanical equivalent. Consequently, our laboratories have produced the Touch Activated Pro- grammer or TAP.
