ABSTRACT:
An electrical control device (8) is operable by a lever (12) and includes a deformable member (50) which is deformed in response to manual pressure on the lever. The deformable member (50) has an electrically conductive surface portion (52) which is arranged to engage a continuous area or track of resistive material (62) such that as a changing manual pressure is applied to the lever (12) a changing amount of the track is electrically bridged or short circuited by said conductive surface portions (52). The resistive area or track is connected to electrical terminals (64, 66) so as to present a continuously variable electrical resistance across the terminals depending on the manual pressure applied.
