Abstract
The present device relates to a two-way drive for producing a rotation movement. The drive has a return spring coupled with a return catch for the purpose of returning a drive lever to its zero position, and at least two friction locked components positioned on the shaft and linked to one another, whereby upon movement of the drive lever away from the zero position these friction locked components in association with an elastic switching component engage with the shaft and on the drive side transfer a torque to the shaft. The return catch (7, 7') is directly secured to one of the friction locked components (2, 3, 4; 2', 3'), whereby the return spring (6, 6') also serves as an elastic switching component. This provides a two-way drive for producing a rotation movement which is flat and compact and is characterised by few components.
