Abstract
Dispositivo de conmutación eléctrica o electrónica formando botón pulsador o teclado con teclas hundibles, que comprende una placa superior provista de un agujero por el que pasa el cuerpo de un botón o de una tecla, una placa inferior dispuesta bajo la placa superior a una distancia predeterminada de la misma y que lleva al menos un elemento de contacto o de conmutación destinado a ser puesto por la tecla o el botón en un estado de conducción o de no conducción según esté la tecla o el botón en una posición de trabajo o de reposo, comprendiendo la parte inferior del cuerpo de la tecla unos medios de recuperación de la tecla o del botón en posición de reposo, cooperando para ello estos medios por atracción magnética con la placa superior antes citada, y siendo la carrera de la tecla o del botón tal que la fuerza de atracción magnética ejercida por estos medios de recuperación sobre la tecla o el botón sea siempre superior al peso de la tecla o del botón, caracterizado porque la tecla o el botón antes citado está asociada con por lo menos un pistón libre destinado a venir a accionar o a mandar, cuando es desplazada la tecla o el botón de su posición de reposo a su posición de trabajo, el elemento de contacto o de conmutación antes citado portado por la placa inferior para hacerle cambiar de estado de conducción, teniendo este pistón libre una carrera muy inferior a la carrera de la tecla o del botón pulsador de tal modo que la duración de una señal eléctrica resultante de un cambio de estado de conducción del elemento antes citado cuando es maniobrada la tecla o el botón, sea superior a una fracción predeterminada del tiempo total de maniobra de la tecla o del botón, siendo el pistón libre axialmente móvil con relación a la tecla o al botón y siendo sometido constantemente a una fuerza de atracción magnética ejercida sobre este pistón por medios de atracción magnética solidarios de la tecla o del botón.
