The control lever has, adjacent a control lever housing, a plate provided with a number of bevelled flat edges corresponding to the number of planes in which the control lever is movable. The plate is tiltable on its flat edges by means of movement of the lever on which is axially movable. A spring is provided between the plate and a fixed abutment on the lever for holding said lever in engagement with a seat and for urging said plate against a planar portion of the housing. When the lever is moved in a given direction, the plate is tilted or rocked about an edge against the action of the spring, with any risk of the lever moving in another undersired plane being effectively eliminated.Other References
