The 4-wire Resistive Touch Screen is the preferred solution for low-cost applications. It consists of a conductive bottom layer of either glass or film and a conductive top film
layer,separated by transparent spacer dots. A voltage is applied across the conductive surface. When pressure is applied to the top layer, it is deflected and makes contact with thebottomlayer resulting in a voltage change. This change is detected by the controller.
Cubbison's 4-wire and 8-wire Resistive Touch Screens can be bonded to a graphic overlay or a membrane switch. This design eliminates the requirement for perimeter gaskets. ESDshielding can also be added.

The 5-wire Resistive Touch Screen consists of a conductive top film layer and glass bottom layer. The basic difference is, in the 5-wire construction, all the electrodes are on the bottom layer and the top layer acts as a voltage measuring probe. When touch pressure is applied to the top layer, the film flexes and makes contact with the bottom layer resulting in a voltage change. Because the top conductive film layer is only acting as a probe, its physical degradation over time is less crucial than in 4- or 8-wire constructions, thus allowing a significantly higher number of actuations.

The 8-wire Resistive Touch Screen has an additional sensing conductive trace on each edge of the touch screen. The trace provides a stable voltage gradient for the controller. The additional traces allows the controller to correct for drift. The 8-wire Resistive Touch Screen has a conductive bottom layer of either glass or film and a conductive top film layer, separated by spacer dots. When pressure is applied to the top layer, the film flexes and makes contact with the bottom layer causing a voltage change. This change in voltage is detected by the controller.
