Abstract
A thumbwheel actuated variable resistor device has a housing comprising a substrate carrying a resistor pattern and a cover with electrical terminals embedded therein and a thumbwheel in the space between the substrate and cover. The thumbwheel carries a pair of conductors which extend from opposite sides thereof to selectively engage portions of the resistor circuit and the terminals so that the resistance between the terminals depend on the thumbwheel position.
