Title: 形状記憶アクチュエータを有する双安定電気スイッチ
IPC: H01H37/50
Filed: 2012-10-22
Abstract: 双安定電気スイッチはアクチュエータとして、スイッチの2つの動作位置に対応する2つの安定位置の間でスナップアクションばね(4)をトグルするように、スナップアクションばね(4)と一体の駆動素子(6)に作用する、1対の対向するSMAワイヤ(1、2)を備え、駆動素子(6)は、SMAワイヤの一方が収縮し他方のSMAワイヤが収縮しないときに2つの対向するSMAワイヤ(1、2)の間に存在する距離よりも短い。このようにして、活動化されたSMAワイヤによって及ぼされる力全体は、スナップアクションばね(4)の抵抗に打ち勝つために用いられ、したがって回路を閉路する、より大きな力をもたらす、より強力なばねを用いることが可能となり、したがってより良好な電気的接触が確実になり、スイッチの信頼性が向上する。
