To provide a combination switch structure for automobiles, eliminating the need for a protection film for covering a through hole in a body.

A movable part 12 interlocking with an operation lever 10 such as a turn switch is provided on a switch body, and a part of the movable part 12 is put through a through hole in the body and confronts a fixed contact provided on a substrate on the backside. A presser plate 23 for restricting the upward movement of the operation lever 10 is extended to the side of the movable part 12 and covers a curved part 12a of the movable part 12 and the upside of the through hole. This makes it possible to prevent dust from invading through a gap between the body and the movable part 12 and reaching the through hole, and therefore a protection film needed in the past for covering the through hole is no longer needed.
