ABSTRACT:
A static pick-up may comprise a sapphire substrate of which the upper sure bears at least two metallic electrodes and a dielectric and the lower surface is metallized in a manner to receive directly an electronic circuit adapted to detect the position of a finger placed on the pick-up. The electrodes are coupled to the lower surface metallization by means of metallized passages. The pick-up may be employed as a control means for introducing and correcting data as displayed by a timepiece.
