<p>A twin control lever arrangement for the control of three functions such as hydraulic valves. The arrangement includes a first control lever (10) mounted on a first mounting means (12) for pivoting about first (A) and second (B) perpendicular axes to operate first and second functions respectively and a second control lever (13) mounted on a second mounting means (15) for pivoting about a third axis (C) aligned with said first axis (A) and a fourth axis (D) parallel to said second axis (B). Pivoting of said second lever (13) about said third axis (C) operates the third function and a link member (32) extends generally perpendicularly to the two control levers (10, 13) to operatively connect the levers by way of pivotal connections at both ends of the link member so that the two levers pivot together about the second and fourth axes to allow either lever to operate the second function. </p> |
