Abstract

1. Interruptor de membrana, caracterizado porque comprende:- una primera lámina de circuito; teniendo dicha primera lámina de circuito al menos una primera lámina (14) de material aislante que lleva una primer medio (16) de contacto eléctricamente conductor, - una segunda lámina que está dotada de una segunda lámina (20) de material aislante, - al menos un elemento táctil (22) formado en dicha segunda lámina (20) y que se extiende desde ella, definiendo dicha segunda lámina (20) de material aislante una superficie plana en la base de dicho elemento táctil (22), - un segundo medio de contacto eléctricamente conductor (26) en dicha superficie plana alrededor de la periferia de dicho elemento táctil (22), - un medio separador (28) entre dichas láminas primera y segunda de circuito, teniendo dicho medio separador (28) una pluralidad de aberturas (30) con lo que dicho elemento táctil (22) es accionable bajo una fuerza aplicada para mover dicho segundo medio (26) de contacto conductor a través dedicha abertura (30) y en contacto eléctrico con dicho primer medio de contacto conductor (16). 2. Interruptor según la reivindicación 1, caracterizado porque dicho elemento táctil (22) es una cúpula de acción elástica (24). 3. Interruptor según la reivindicación 2, caracterizado porque dicha cúpula de acción elástica (24) tiene una forma arqueada con vértice aplanado. 4. Interruptor según cualquiera de las reivindicaciones 1 a 3, caracterizado porque dicho segundo medio (26) de contacto conductor tiene forma modular. 5. Interruptor según la reivindicación 4, caracterizado porque dicho primer medio (16) de contacto conductor tiene una forma anular correspondiente a dicho segundo medio (26) de contacto conductor. 6. Interruptor según cualquiera de las reivindicaciones 1 a 5, caracterizado porque dichos medios primero y segundo de contacto conductor están constituidos de tinta conductora. 7.Interruptor según cualquiera de las reivindicaciones 1 a 6, caracterizado porque dichos medios primeroy segundo de contacto conductor están segmentados, permitiendo así contactos paralelos múltiples en dichas láminas superior e inferior de circuito. 8. Interruptor según cualquiera de las reivindicaciones 1 a 7, caracterizado porque incluye una lámina rigidizante (12) en fijación de soporte con dicha lámina inferior de circuito. 9. Interruptor según cualquiera de las reivindicaciones 1 a 8, caracterizado porque dicho elemento táctil (22) se halla libre de material eléctricamente conductor dentro de la periferia de dicho elemento táctil, con que dicho elemento táctil (22) es apropiado para alumbrado posterior. 10. Interruptor de membrana.
