Control device for a push-piece, in particular for time piece, and portable electronic instrument comprising same

Abstract

There is disclosed a control device including (i) a support (), (ii) an electronic module () arranged in or on the support, (iii) a push-button (to) mounted to be mobile on the support so as to have a travel in translation along an axis of actuation, (iv) a first contact element () including a mobile part () placed on the axis of actuation so as to be actuated by the push-button, and (v) a second contact element () with which the mobile part of the first contact element can be brought into contact in order to establish an electric connection between the two contact elements, the electronic module including at least one contact pad () in electric contact with the first or second contact element, the other contact element having a determined electric potential. The first and second contact elements are respectively formed of a first metal contact strip () and a second metal contact strip () both carried directly by said support (). The first and second contact strips, as well as the push-button, are thus mounted on the same frame, namely the support, such that the arrangement and the travel of the push-button can be controlled and fixed with a high level of precision. There is also disclosed a portable electronic instrument, such as a timepiece, including such a push-button control device.
