ある。Description: TECHNICAL FIELD The present invention relates to a relay such as a relay and a switch.

〔従来の技術〕[Conventional technology]

従来、前記継電器として電磁石の励磁・消磁に基づい
て絶縁材からなる可動部材を動作させるとともに、可動
部材に設けた突起部で可動接触片を動作させて接点機構
を開閉するようにしたものが提案されている。Conventionally, there has been proposed a relay in which a movable member made of an insulating material is operated based on excitation and demagnetization of an electromagnet and a movable contact piece is operated by a projection provided on the movable member to open and close a contact mechanism based on excitation and demagnetization of an electromagnet. Have been.

この種の継電器では、可動接触片に対する突起部の接
触位置が変われば、接点の接触圧やコンタクトフェロー
等が変わり、動作特性にばらつきを生じる。特に、継電
器が小型化してくると、わずかな誤差でも特性が大きく
変動する。したがって、突起部と可動接触片の接触位置
を正確に測定する必要がある。In this type of relay, if the contact position of the protruding portion with respect to the movable contact piece changes, the contact pressure of the contact, the contact fellow, and the like change, causing variations in operating characteristics. In particular, as relays become smaller, even small errors cause large fluctuations in characteristics. Therefore, it is necessary to accurately measure the contact position between the protrusion and the movable contact piece.

〔発明が解決しようとする課題〕[Problems to be solved by the invention]

しかしながら、従来の継電器では、第5,6図に示すよ
うに、可動接触片102に対する突起部100の接触位置がば

The movable contact piece 102 was pushed by 101.

このため、可動接触片102に対する突起部100の接触位

認識できるが、正確な接触位置まで判断できなかった。For this reason, the contact position of the protrusion 100 with the movable contact piece 102 could not be accurately measured. That is, since the contact portion of the projection portion 101 is a curved surface, there is a protrusion 101 width: in D ₁ to be in contact with the movable contact piece 102 can recognize, but can be determined until the exact contact position Did not.

〔課題を解決するための手段〕[Means for solving the problem]

本発明は前記問題点を解決するためになされたもの
で、前記継電器において、前記突起部の側面であって前

Are provided.

〔作用〕[Action]

以上の構成を備えた継電器では、突起部と可動接触片
