Abstract
An activation device for transmitting a user input to a control device has an engaging element that forms a first housing part and a feeding element that forms a second housing part. The engaging element has a push magnet, whose magnetic field extends into the feeding element and the feeding element has a push magnet that can be displaced without contact through exposure to the magnetic field. The engaging push magnet can be displaced in the direction of the feeding element by pressure-activating the activation device, and is set up to exert a magnetic force on a corresponding feeding push magnet. The engaging element and feeding element each have at least one rotating magnet that can be displaced parallel to an intermediate plane running between them. The engaging rotating magnet of the engaging element exerts a magnetic force on a corresponding feeding rotating magnet of the feeding element.
