PROBLEM TO BE SOLVED: To reduce force in the separation direction acting between connection protrusions of an operation body and elastic arms of a support member, and to miniaturize a swing operation type switch device which selectively turns on plural switching elements by swing operation of the operation body. SOLUTION: This swing operation type switch device comprises an operation body 1 swingingly operated by a user; a support member 2 swingingly supporting the operation body 1; a flexible board 3 having a tact switch turned on by swing operation of the operation body 1; and a fixing plate 4 supporting the operation body 1, the support member 2 and the flexible board 3. The lower face center of the operation body 1 is perpendicularly formed with a support shaft 1b that is the swing center, while the lower face of the operation body 1 is alternately formed with four push protrusions 1c and four connection protrusions 1d around the support shaft 1b at even intervals of 45 degrees in the circumferential direction. The support member 2 is formed with four elastic arms 2c in a cantilever state with the center sides as fixed ends. By hot-welding each the connection protrusion 1d to the free end side of each the elastic arm 2c, the operation body 1 is integrated with the support member 2 movably to the support member 2.
