A switch device comprising:
- an operation member;
- a snap-action mechanism configured to be actuated in response to operation of the operation member;
- and a housing accommodating the snap-action mechanism, wherein the snap-action mechanism includes a movable member including one of a detecting section and a section to be detected provided on the other end side of the movable member, the movable member being configured to swing in a first direction relative to a fixed base fixed to the housing with one end side serving as a first pivot point to change a relative position between the detecting section and the section to be detected;
- a fixed member including the other of the detecting section and the section to be detected;
- a drive member having one end side engaged with the other end side of the movable member at a second pivot point;
- and a contact spring formed of a plate spring, the contact spring having one end side engaged with the other end side of the drive member at a third pivot point located on the first pivot point side and the other end side engaged with the fixed base at a fourth pivot point located on the second pivot point side, wherein a bent portion intersecting the drive member is provided between the one end and the other end of the contact spring.
