Abstract

PURPOSE:To provide a piano handle type switch in which a gap between a piano handle and a cover is absorbed so as to eliminate a shaking. CONSTITUTION:In a piano handle 43 made of a synthetic resin, the upper end of a spring body 30 which consists of a plate-form metallic spring is fixed to the lower end of its one end and hung down, and the holding position to a cover 5b of the piano handle 43 is formed by a tubular lower part 90a formed at the lower side of the spring body 90. The tubular lower part 90a of the spring body 90 is compression-inserted in a recess 54 while its diameter is being contracted, and the piano handle 43 is pivoted rotatable to the cover 5b making the pressure-inserting position as the fulcrum. The outer surface of the tubular lower part 90a is squeezed to the inner surface of the recess 54 including the sloped lower surface 80a of a locking projection 80, so as to suppress a shaking in the up and down direction of the piano handle 43, and furthermore, it is squeezed to the inner surface of the recess 54 at the opposite side of the locking projection 80, so as to suppress the movement in the longitudinal direction of the piano handle 43.
