A switch device includes a body, an insulator which forms an outer casing with the body, a first engagement portion formed at a side portion of the body, a flange portion formed at an edge part of the side portion of the body, a second engagement portion formed on the insulator so as to be engaged with the first engagement portion, and a pressing portion which is formed on the insulator and is adapted to press the flange portion in a state that a plane part of the pressing portion is in line-contact with the edge part of the flange portion when the first engagement portion is engaged with the second engagement portion. The edge part of the flange portion is in intimate contact with the pressing portion by a restoring force of the flange portion under a condition that the flange portion is pressed by the pressing portion, and the flange portion urges the second engagement portion engaged with the first engagement portion in a restoring direction of the flange portion so as to reinforce the engagement of the first engagement portion with the second engagement portion.
