ABSTRACT:
A handle (12) is pivotally mounted on a support (11) and is connected to a potentiometer (21) by a linkage (24) for selectively varying the resistance of the potentiometer upon manipulation of the handle. The linkage includes a link (25) adjustably connected to the handle for varying the degree of relative movement between a housing (22) and rotary adjustment shaft (23) of the potentiometer to thus vary the range of resistance thereof in response to a same increment of movement of the handle. The linkage may include a hinge assembly (34) and a biasing spring (31) or the link may be connected to the adjustment shaft (23b) of the potentiometer directly.
