Abstract

A touch sensitive device for controlling a function of a timepiece is formed with a condenser having a capacity independent of the area of the device touched. A conductive stem is fixed in a timepiece case and is electrically insulated from the case by a mounting member. A head is fixed on an end of the stem adjacent the outside of the timepiece to form one of the condenser electrodes. A thin layer of insulating material covers the outside of the head and forms the condenser dielectric. A layer of conductive material is fixed on a side of the dielectric material opposite the head and forms the second condenser electrode. When the second electrode is energized by the touch of the user, the entire second electrode is energized independent of the area touched by the user, giving the condenser a capacity independent of the area of the second electrode touched.
