ABSTRACT:
A control lever arrangement (10) for longitudinally moving an actuating member such as a Bowden cable (11) between first and second positions. The arrangement includes first (13) and second (14) mutually inclined cam slots and a control lever (15) which has a handle at one end and which is pivotally mounted (20) at the other end on a follower (16) for engagement with the first cam slot. The lever (15) carries guidance means (17) for engagement with the second cam slot and is connected (21) with the actuations member (11), so that, as the control lever is rotated (X1,X2) about its mounting (20) on the follower (16) to move the actuating member between its first and second positions, the follower moves along the first (13) cam slot as the guidance means (17) moves along the second cam slot (14) and the point of contact of the follower (16) with the first slot (13) moves across the line of action (33) of the actuating member (11) so that the lever goes over-center.
