Abstract
An operating device is proposed for an electrically height-adjustable table having at least one electrical drive (EA) for adjusting the height of a table top (TP) of the table, and a controller (CTRL) for controlling the drive (EA). The operating device has an actuating element (BE, EMS, CS) to be arranged in the region of the table top (TP), a force sensor (FS), which is designed to measure a force acting on the table top (TP), and an evaluation circuit (EV). This circuit is designed to detect an actuation of the actuating element (BE, EMS, CS) during a height adjustment of the table top (TP), to receive measurement values from the force sensor (FS) within a predetermined period of time after the detected actuation, to determine a force alteration value from the received measurement values, and if the force alteration value is greater than a threshold value, to issue a control signal to the controller (CTRL) in order to initiate a height adjustment of the tabletop (TP) in a direction, depending on a sign of the force alteration value.
