Patent ID: 8371745

Claim:
A double-acting control element for a wristop computer, which has a case, which control element comprises: a crown, which is movable in an axial and radial direction relative to the case of the terminal device and at least partly outside thereof, a reaction bar, which connects to the crown parallel to its axial direction, in such a way that the reaction bar is arranged to transmit the movement of the crown inside the case, switches, which are fixed inside the case, of which switches at least one, an axial switch, is arranged to engage from the axial movement of the crown, and at least another, a radial switch, is arranged to engage from the radial movement of the crown, a slide, which is at least partly inside the case and which connects to the reaction bar, in such a way that the slide is arranged to transmit the axial movement of the reaction bar to the axial switch, and a gearwheel, which is inside the case, and which gearwheel is fitted around the slide by means of a sliding-form fit, in such a way that the gearwheel is arranged to transmit the radial movement, transmitted by the reaction bar to the slide, to the radial switch.
