With the aid of the invention, a double-acting control element for a wristop computer or similar and a method for controlling a wristop computer or similar terminal device are created. The control element according to the invention comprises a crown (10), which can be moved in axially and radially relative to the case (20) of the terminal device and at least partly outside it, a reaction bar (18), which is connected to the crown (10) parallel to the axial direction of the crown, in such a way that the reaction bar (18) is arranged to transmit the movements of the crown (10) to the inside of the case (20), and switches (22, 24), which are permanently fitted to the inside of the case (20), of which switches (22, 24) at least one, an axial switch (22), is arranged to switch on from the axial movement of the crown (10) and at least another, a radial switch (24), is arranged to switch on from the radial movement of the crown (10). In addition, the control element comprises a slide (12), which is at least partly inside the case (20) and which connects to the reaction bar (18) in such a way that the slide (12) is arranged to transmit the axial movement of the reaction bar (18) to the axial switch (22), as well as a gearwheel (13), which is inside the case (20) and which is around the slide (12) in such a way that the gearwheel (13) is arranged to link the reaction bar (18) to the slide (12) to transmit the radial movement to the radial switch (24).
