Abstract

An input device for inputting at least two control commands into an electronic system, having a housing (10) accommodating a combined switching and encoding circuit device (13) with a switching control means (15) and an encoding control means (16); and first and second manually accessible operating elements (19, 20) for operating the switching control means (15) and the encoding control means (16), respectively. To provide another input device that allows eyes-free operation of multiple functions and has an improved robustness, a separation means (22) is arranged between the first and the second operating element (19, 20) so as to clearly separate the operations of the elements from each other.
