PROBLEM TO BE SOLVED: To enable to widen freedom of setting height and shape of moderation grooves while fitting them at the side of movable contacts and improve operation feeling without bringing about a cost hike. SOLUTION: With the switch attaching and detaching movable contacts to and from fixed contacts as steel balls 123 move over and swing movable pieces 53a, 53b, 55a, 55b, 57a, 57b, the movable contacts 53a, 53b, 55a, 55b, 57a, 57b are provided with contact parts of conductive material and resinous flat moderate parts having moderation grooves. The moderate parts are arranged in erection against a housing 6, the steel balls 123 are contained in a ball support part through coil springs 125, and insertion-coupling grooves loosely inserted into end edges of the movable pieces 53a, 53b, 55a, 55b, 57a, 57b are arranged at the opening of the ball support parts.
