  • Publication number: 20230386768
    Abstract: A switch device includes, a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion, a first fixed terminal that contacts the movable terminal when the spring is not bent, a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring, a case including an opening, and a cover that closes the opening and is separate from the first fixed terminal. When the opening is closed by the cover, the first fixed terminal is positioned in the case by the cover.

  • Patent number: 11495419
    Abstract: A switch device includes two fixed contacts and a movable contact of which position is changed when an operation unit is operated to selectively contact the fixed contacts. The switch device also includes a snap action mechanism that switches a contact state of the movable contact with the fixed contacts by deforming a spring portion in accordance with an operation amount of the operation unit. The switch device also includes a control unit that determines an operation state of the operation unit based on a detection signal received from the fixed contacts and the movable contact.
