PROBLEM TO BE SOLVED: To provide a narrow two step action push-on switch having equivalent outer width to a single step action push-on switch operating in a controlled manner. SOLUTION: The push-on switch is composed of a disk part 15 curved in a spherical surface and two T-shaped projection parts 16, 17 projecting from a point symmetry position of an outer circumference thereof and an elastic metal thin plate moving contact body 14 in which the width of the expanded parts 16B, 17B of the tips of the leg parts 16A, 17A of the T-shaped projection parts 16, 17 is equal to or less than the disk part 15 is mounted on an inner bottom surface of s switch case 11 at end parts of the expanded part 16B, 17B in such a manner that an outer circumference of the disk part 15 faces two periphery fixed contacts 12B, 12C and that a center thereof faces to a center fixed contact 12A at a designated interval. Consequently, narrow two stage action switch is materialized. COPYRIGHT: (C)2003,JPO
