<p>A variable resistance device comprises a resistive member having a resistive rubber material (74). A first conductor (78) and second conductor on substrate (72) are configured to be electricaly coupled with the resistive member (74) at a first contact location over a first contact area, and a second contact location over a second contact area, respectively. The resistance between the first conductor at the first contact location and the second conductor at the second contact location is equal to the sum of a straight resistance component and a parallel path resistance component. The straight resistance component increases or decreases as the distance between contact locations increases or decreases respectively. Changing the contact locations and areas presets the components such that the change in resistance can be governed by the parallel or straight resistance components.</p> |
