PROBLEM TO BE SOLVED: To provide a press button switch of high reliability in contacting where a lower part movable contact point is easily fitted to a housing while the dust and darts are prevented from entering the contact point part. SOLUTION: An annular adhesive sheet 8 comprising a through hole 6a at its center is so provided to a housing part 1a of a housing 1 as to cover the upper surface side of a lower part movable contact point 4. The top part of a swelling part 4a of the lower part movable contact point 4 is exposed from the through hole 6a of the adhesive sheet 6 to allow contacting to an upper part movable contact point 5. The circumferential part of the lower part movable contact point 4 is glued and held, across the entire circumference, by the housing part 1a of the housing 1 using an annular part 6b of the adhesive sheet 6.
