ABSTRACT:
An infinitely variable rotary resistor assembly has a substantially conventional rotary resistance element 1 mounted for rotation in a housing 2, on rotation of a projecting shaft 4. The resistance element 1 is biased to a predetermined position by spring means 14,15 mounted within the housing 2 on a shaft 6.
In an alternative form of the invention, a substantially conventional rotary variable resistor 20 is biased to a predetermined position by a biasing device mounted over the housing of the rotary variable resistor 20 to snap engage therewith, and coupling with an accessible part 37 of a rotary resistance element in the resistor.
