Abstract

A rotary actuator with a magnetically produced tactile sense is provided, in particular for a motor vehicle. The rotary actuator includes two plane-parallel permanent magnets, with the first magnet being arranged in a fixed position in a housing of the rotary actuator, and in which case the second magnet can be rotated with respect to the first magnet by a handle of the rotary actuator.
