  • Patent number: 8823474
    Abstract: To promptly extinguish an arc generated between contacts with a simple and inexpensive structure without negatively influencing the spring property of a movable contact piece. A contact switching mechanism includes a fixed contact piece with a fixed contact and a movable contact piece with a movable contact which faces the fixed contact in a contactable manner. At least either one of the contact pieces is provided with an extension which extends toward the contact of the remaining contact piece.

  • Patent number: 8558647
    Abstract: Provided is a technology which has a simple structure, is easy to manufacture, and does not increase cost. A terminal member to be press-fitted into a terminal hole formed in a base, includes a press-fitted portion which is to be press-fitted in the terminal hole, and a terminal portion extending from the press-fitted portion and protruding from the base. The terminal portion is formed by folding a plate-like body such that folded portions overlap a planar portion. At least one of the folded portions has a cut-away portion extending from the base, respectively at an edge near the press-fitted portion. A sealing agent can be injected into the terminal hole via the cut-away portions.
