摘要：
A self-propelled working device has a housing and an operating element arranged on the housing. A pivot bearing is arranged on the housing. A lid is pivotably arranged on the housing so as to pivot about a pivot axis of the lid, wherein the lid has a closed state in which the lid covers the operating element and an open state enabling access to the operating element. The lid has a bearing section interacting with the pivot bearing, wherein the bearing section and the pivot bearing define the pivot axis of the lid. A first Hall sensor is arranged in the housing and monitors a pivot position of the lid. A first magnet is arranged on the bearing section of the lid. The first magnet rotates when the lid pivots about the pivot axis and the magnetic field of the first magnet is detected by the first Hall sensor.
