Abstract

"PROCESSO PARA FABRICAR UM COMUTADOR BIESTáVEL, E, COMUTADOR BIESTáVEL". A presente invenção provê um comutador biestável usando uma liga de memória de forma, e um método para fabricar o mesmo. Mais especificamente, o comutador biestável inclui um substrato que tem pelo menos uma fonte de potência. Uma chapa flexível que tem uma primeira extremidade distal presa ao substrato; um contato de ponte formado a uma segunda extremidade distal oposta da chapa flexível; e pelo menos um elemento ativado por calor conectado a uma primeira superfície da chapa flexível e entre a segunda extremidade distal e a fonte de potência. Durante operação, corrente da fonte de potência passando pelo elemento ativado por calor para indiretamente dobrar a chapa flexível e curto-circuitar os contatos de sinal no substrato com uma força sustentável."PROCESS FOR MANUFACTURING A BIESTABLE SWITCH, AND, BIESTABLE SWITCH". The present invention provides a bistable switch using a shape memory alloy, and a method for manufacturing it. More specifically, the bistable switch includes a substrate having at least one power source. A flexible plate having a first distal end attached to the substrate; a bridge contact formed at an opposite second distal end of the flexible plate; and at least one heat activated element connected to a first surface of the flexible plate and between the second distal end and the power source. During operation, current from the power source passing through the heat activated element to indirectly bend the flexible plate and short the signal contacts on the substrate with a sustainable force.
