Abstract

"TECLADOS E COMUTADORES DE TECLAS". A invenção refere-se a um teclado com ambas regiões de tecla elevada (11) e não-elevada (22), e comutadores de tecla (12) dispostos abaixo de ambos os tipos de regiões de tecla. As regiões de tecla não-elevadas proporcionam, cada qual, saída de caractere correspondente com base em um algoritmo de operação que considera o acionamento de pelo menos uma região de tecla elevada adjacente, bem como o acionamento do comutador de tecla abaixo da região de tecla não-elevada. O teclado inclui uma esteira de tecla (41) que é rigidamente mantida em seu perímetro em uma condição esticada através de um substrato de comutador (23). Os comutadores de tecla incluem domos de pressão metálicos (12) que possuem uma região central elevada (212) formando uma cavidade voltada para baixo (13) definida em sua borda por um sulco (214) disposto acima dos contatos de comutador (21) que se encaixa eletricamente com múltiplos contatos de comutador em uma zona de contato anular (230).
