Abstract

A switching device, in particular a position sensing switching device, generates switching signals. The position sensing switching device comprises at least one switching unit and at least one activation unit, the switching unit reacting to a relative spacial displacement of the switching unit and the activation unit with respect to one another by outputting appropriate switching signals. The switching unit is embodied as an inductive switching unit and the activation unit is embodied as an inductive damping unit. The position sensing switching device according to the invention is preferably applied in gear-speed-changing units for automatic gearboxes.
