Abstract: An operating device may have a moving operating element, a housing a magnetorheological elastomer, and a coil. An end of the operating element may be supported in the housing. The magnetorheological elastomer may result in a first operating characteristic for operating the operating element in a resting state and a second operating characteristic for the operation in an activated state. The coil may generate a magnetic field that transfers the magnetorheological elastomer between the resting state and the activated state.
