側壁に密着すると共に、一部が凹部４ｄから外方
に突出した状態となつている。 A sealing member 6 is made by impregnating an elastic body such as a sponge with a lubricant such as silicone grease, and the sealing member has a shape that can be fitted into the annular recess 4d of the operating member 4. Recess 4
d, the sealing member 6 is in close contact with the side wall of the recess 4d, and a portion thereof protrudes outward from the recess 4d.
７はコ字型の取付板で、該取付板はスイツチ基
板１にめ付けられて、スイツチ基板１と操作部
材４とが組み合わされる。 Reference numeral 7 denotes a U-shaped mounting plate, which is fitted onto the switch board 1 to combine the switch board 1 and the operating member 4.
そして、スイツチ基板１と操作部材４が組み合

材６がスイツチ基板１面に密着し、本体部４ｃの
空洞部４ｂがスイツチ基板１と密封部材６とによ
つて密封され、従つて、空洞部４ｂ内に位置した
可動接片５とスイツチ基板１上の固定接点２…は
外部から完全に遮断された状態となる。 When the switch board 1 and the operating member 4 are combined, the sealing member 6 attached to the operating member 4 is in close contact with the switch board 1, and the cavity 4b of the main body 4c is connected to the switch board 1 and the sealing member 6. Therefore, the movable contact piece 5 located in the cavity 4b and the fixed contacts 2 on the switch board 1 are completely cut off from the outside.
また、組み立て後、操作部４ａを操作（回転）

かに摺動してスイツチ基板１が摩耗することな
く、また操作感触の良好なスイツチが得られる。 That is, according to the present invention, in a switch in which the main body portion 4c provided with the movable contact piece 5 rotates facing the switch board 1 provided with the fixed contact 2, the movable contact piece 5
The movable contact piece 5 and the fixed contact 2 are provided with a sealing member 6 that is interposed so as to be in close contact with the main body 4c and the switch board 1, respectively, and is made of an elastic body impregnated with lubricant. The sealing member 6 is sealed in the cavity 4b and isolated from the outside, and there is no discoloration or corrosion of the contact due to the external environment, providing stable contact over a long period of time. The switch slides smoothly on the surface of the switch board 1, so that the switch board 1 is not worn, and a switch with a good operating feel can be obtained.
