The variable resistor (102) further includes an elastomeric actuator (300) having opposing upper and lower surfaces (310, 305), wherein the lower surface (305) is conductive. The lower surface (305) electrically couples the first terminal (145) to successive portions of the resistor network (205) as an increasing force is applied to the upper surface (310) of the elastomeric actuator (300), in response to which the resistance between the first and second terminals (145, 150) varies. | |
