PCT No. PCT/DE94/00195 Sec. 371 Date Nov. 15, 1995 Sec. 102(e) Date Nov. 15, 1995 PCT Filed Feb. 17, 1994 PCT Pub. No. WO94/19735 PCT Pub. Date Sep. 1, 1994A manual controller including a control lever having a lower end; a housing having a bottom; a bearing held in the housing and supporting the control lever for pivotable deflection in two orthogonal axes around a fixed point from a zero position to a maximum pivot angle relative to the zero position while the lower end of the control lever moves over a path lying in a spherical surface having a radius R; and converter devices which translate pivotal movement of the control lever from its zero position into an electrical signal. The bearing is an elastomer joint having a transition part extending between a rim and an inner part for imposing on the control lever an elastic restoring force from all deflection positions toward the zero position of the control lever while simultaneously maintaining the spatial position of the fixed point. The bottom of the housing has a preshaped part for guiding the lower end of the control lever, the preshaped part having the shape of a segment of a sphere which has a radius corresponding to the radius R, and the lower end of the control lever is movable along the surface of said preshaped part during deflection movement of the control lever.
