In the multi-directional switch, a flange part is formed on the lower part of the operation body where a user conducts tilting actions, a contact brush of a leaf spring shape is provided which is installed separately from the operation body and independently, interposed between the operation body on which the flange part is formed and a fixed contact. 多方向スイッチにおいて利用者が傾倒動作を行う操作体の下部にフランジ部を形成し、フランジ部を形成した操作体と固定接点との間に、操作体とは別個独立に設けられて介在する板バネ状接点ブラシを備える。 - 特許庁
To avoid deterioration in the reliability of an actuator used for the mobile communication terminal thereby enhancing the vibration characteristic by providing a structure that prevents a leaf spring from being deformed even before and after dropping a mobile communication terminal such as a cellular phone and a pager including the multi actuator. マルチアクチュエータを含む携帯電話、フェーザー等の移動通信端末機の落下前後でも上記板スプリングの変形を防止できる構造を提供することで、移動通信端末機に使われるアクチュエータの信頼性低下を防止して振動特性を向上させる。 - 特許庁
