ABSTRACT:
A control lever for a vehicle or a machine tool, in particular for an industrial truck, is disclosed for the generation of an electrical control signal. The actuation travel of the control lever is limited by a stop point that is defined by a stop and the control lever has means to generate a restoration force. The stop has an elastic component, as a result of which an at least slight deflection of the control lever beyond the stop point is possible. The elastic component of the stop is realized so that in the event of a deflection beyond the stop point, the restoration force, as a function of the deflection, increases to a greater extent than in the event of a deflection of the control lever between a neutral position and the stop point. When a defined, safety-critical deflection of the control lever is reached, whereby the control lever during this safety-critical deflection is moved beyond the stop, a signal can be generated by an electrical sensor, as a result of which a safety function of the vehicle or of the machine tool is actuated.
