Abstract

Teclado para teléfonos, del tipo de los que comportan una carcasa compuesta por dos piezas, de las que una incorpora las ventanas para el montaje y guiado de las teclas, encontrándose dichas teclas organizadas para provocar cada una el cierre de dos contactos que están instalados sobre un sustrato montado dentro de la carcasa, que se caracteriza esencialmente porque los mencionados contactos se instalan con la colaboración de unos soportes modulares, compuestos cada uno por dos elementos independientes, que se abrochan entre si, determinando en su reunión medios de posicionamiento para los contactos pertenecientes al soporte modular inmediato; porque los medios de que se provee a las teclas para provocar dos cierres simultáneamente consisten en dos protuberancias iguales, emergentes solidariamente de puntos diametralmente opuestos de sus zonas inferiores respectivas; porque tales teclas cuentan con medios posicionadores hacia su situación e reposo, determinados por empujadores de acción elástica que reaccionan contra el propio sustrato en donde los contactos se instalan; y porque las dos piezas componentes de la carcasa del conjunto se acoplan entre ellas de forma estanca al polvo, incluso en los puntos de abroche.
