PROBLEM TO BE SOLVED: To provide a small push switch used for a variety of electronic devices detection with a simple operation of structure members, excellent in assembly work performance, having large operation stroke. SOLUTION: On a switch substrate 11 in which fixed contacts 12, 13 are fixed by insert molding, a movable contact 14 made of elastic metal film is mounted so that a tongue piece part 14B keeps a prescribed insulation gap, and an elastic body 15 of an elastic material which has a protrusion 15C at the top of the lower-opened thin conical part 15A and a hanging down part 15F inside the top part, and presses the peripheral part 14A of the movable contact 14 at the lower end 15B, and an operating body 16 are placed on the protrusion 15C of the elastic body 15. A cover 17 which has a hole 17A for projecting the operational body 16 from the upper side to the center is put on and fixed to the periphery of the switch substrate 11.
