Abstract
A joystick for controlling the functions of machines and/or vehicles comprises an actuator which can be moved in different directions by means of a joint having preferably two degrees of freedom, wherein the back-and-forth motions of the actuator occurring in a first plane are subjected to an active force feedback in the form of an electromotor and a reduction gear, and the back-and-forth movement of the actuator which occurs in a second plane perpendicular to the first plane is subjected to a passive force feedback in the form of a sprung reset device. In order to make such a joystick which allows for a low-cost serial production, the invention proposes that the reduction gear is designed with low backlash and is connected on the output side to the actuator via a preferably leaf-spring assembly which connects a swing arm to a joint part.
