PCT No. PCT/SE90/00544 Sec. 371 Date Mar. 27, 1992 Sec. 102(e) Date Mar. 27, 1992 PCT Filed Aug. 24, 1990 PCT Pub. No. WO91/02912 PCT Pub. Date Mar. 7, 1991.A lever has a knob and an elongated part. In one of its ends, the elongated part carries the knob and is at a distance from the end connected to a mechanism that is to be operated, such as a gear box. The knob includes an electrical switch and is movable radially relative to the longitudinal axis of the lever part and has a cavity into which the lever part protrudes with one of its ends which also functions as a second contact element. The cavity has a peripheral surface which defines a space with the surface of the end of the lever part. In the space there is located an elastically deformable, ring-shaped centering element which at its outer periphery abuts against the peripheral surface of the space and at its inner periphery abuts against the surface of the lever part and a ring-shaped, electrical contact element. The contact element, which is part of the switch, is immovably connected to the knob and adapted to follow the knob in its radial movements. The centering element strives at centering the contact element relative to the end part of the lever part. In a neutral position for the knob, the movable contact element defines a space with the end part of the lever part. By a manual sidewards movement of the knob relative to the lever part, the ring-shaped contact element will be moved into an eccentric position and into contact with the second contact element.
