PROBLEM TO BE SOLVED: To provide an operation switch device by which operation sounds of a plurality of switch members are uniform and sharp.SOLUTION: An operation switch device comprises: a plurality of switch members 3 in each of which a metal movable contact having a reverse spring function is pressed and operated; and a substrate member 9 on whose first surface 9p the plurality of switch members 3 are mounted. The substrate member 9 is configured to be held between a first case body 4 and a second case body 6. On the first case body 4, a plurality of first tone color adjustment members 14 abutting on the first surface 9p in a region in the vicinity of the switch members 3 are integrally molded. On the second case body 6, a plurality of second tone color adjustment members 26 abutting on a second surface 9r of the substrate member 9 corresponding to a substantially back region of the switch members 3 are integrally molded. The substrate member 9 is held while always receiving stresses from both the first tone color adjustment members 14 and the second tone color adjustment members 26. |
