ABSTRACT:
A lever (14) is fixed to a shaft (15) which can be connected to a rotation shaft (19) of a device such as a potentiometer. The shaft (15) is journaled in a pair of support plates (10, 11) which are rigidly connected to one another, and brake discs (23) having brake linings (22) are arranged between the lever (14) and the support plates (10, 11). Cup springs (24) provide a spring force acting transversely to the operational direction of the lever (14), so that frictional forces provided by the brake linings (22) assure a smooth and jolt free operation of the lever (14).
