Claims (1)

【実用新案登録請求の範囲】[Scope of utility model registration request] 固定子接触子の一部および可動接触子の一部がそれぞれ
変態点温度の異なった一方向性の形状記憶合金で形成さ
れ、両接触子の接触抵抗が高くなった場合に接点の発熱
量に対応して、両接触子の接触点を多数回変化させるよ
うにしたことを特徴とする電気接触子。A part of the stator contact and a part of the movable contact are each made of a unidirectional shape memory alloy with a different transformation point temperature, and when the contact resistance of both contacts becomes high, the amount of heat generated by the contact increases. Correspondingly, an electric contact is characterized in that the contact points of both contacts are changed many times.
