Abstract
COMUTADOR DE PRESSãO, E, MéTODO PARA A PRODUçãO DO MESMO.Um comutador de pressão para pressões de até uma pressão máxima permissível (Pmax), com um alojamento (1) e uma membrana (2), por meio do que a membrana é presa ao alojamento. A membrana tem uma face exposta sobre a qual uma pressão pode atuar e ela sendo deformada quando uma pressão atua sobre a mesma. O comutador de pressão compreende um meio (4) que converte a deformação da membrana em um curso, bem como, um sistema de contato elétrico que interage com este meio. O meio faz com que uma deformação de membrana atue sobre o sistema de contato elétrico. O comutador de pressão também compreende um membro de encosto sólido moldado (5) que preenche completamente uma cavidade entre uma parede interna do alojamento e a face da membrana oposta à face exposta quando a membrana é exposta à pressão máxima permissível Pmax.
