Abstract
First and second movable contacts are connected to a first movable contact piece. A second movable contact piece is provided separately from the first movable contact piece. Third and fourth movable contacts are connected to the second movable contact piece. A drive device moves the first movable contact piece and the second movable contact piece by moving a movable iron core by a magnetic force generated from a coil. In a state where the first to fourth movable contacts are contacts the first to fourth fixed contacts, respectively, the first movable contact piece and the second movable contact piece are electrically connected in parallel with the first fixed terminal and the second fixed terminal.
Claims13
A relay comprising:
- a first fixed terminal;
- a first fixed contact connected to the first fixed terminal;
- a third fixed contact connected to the first fixed terminal;
- a second fixed terminal;
- a second fixed contact connected to the second fixed terminal;
- a fourth fixed contact connected to the second fixed terminal;
- a first movable contact piece;
- a first movable contact that faces the first fixed contact, the first movable contact being connected to the first movable contact piece;
- a second movable contact that faces the second fixed contact, the second movable contact being connected to the first movable contact piece;
- a second movable contact piece provided separately from the first movable contact piece;
- a third movable contact that faces the third fixed contact, the third movable contact being connected to the second movable contact piece;
- a fourth movable contact that faces the fourth fixed contact, the fourth movable contact being connected to the second movable contact piece;
- a link member connected to the first movable contact piece and the second movable contact piece;
- and
- a drive device including a coil and a movable iron core connected to the link member, the drive device being configured to move the first movable contact piece and the second movable contact piece by moving the movable iron core by a magnetic force generated from the coil, wherein
- in a state where the first to fourth movable contacts contact the first to fourth fixed contacts, respectively, the first movable contact piece and the second movable contact piece are electrically connected in parallel with the first fixed terminal and the second fixed terminal.
