The structure of the leaf spring of the conductive liquid contact switch according to the present invention is completely the same as that of the conventional leaf spring, but around the elongated hole 1Ia through which a part of the mover 3 is exposed (the surface facing the fixed electrode 1). A region b that is not wetted by the conductive liquid is provided in the movable element 3 to limit the bridge length of the conductive liquid generated between the movable element 3 and the fixed electrode. For example, the region +b which cannot be cut by the conductive liquid may be plated with chromium and further oxidized to form chromium oxide. Tungsten, chromium alloys, nickel, iron, etc. can also be used in place of chromium.
