Abstract
On a foot-controlled operating element for motor-driven items of furniture, particularly lift beds (1) and treatment couches, with a motor-driven lifting mechanism and a foot switch for operating the drive, where the drive function can be activated by exerting a load on the foot switch, provision is made, for the purpose of deactivating the drive motor of the lifting mechanism, preferably reversing the lowering movement until the operator's foot is released, for the foot switch to display at least a second switching step, which can be triggered by increasing the operating force exerted by the foot beyond the normal load value, and stops the downward movement of the item of furniture.
