Abstract
Disposición de pulsadores para aparatos receptores de telecomunicación, en particular para receptores de televisión, con pulsadores que se disparan mutuamente para conectar valores eléctricos almacenables, discrecionalmente ajustables, de memorias de canales constituidas por varios divisores de tensión para la sintonización por diodos de capacidad, con botones de presión giratorios asociados a los pulsadores correspondientes, susceptibles de ser hechos girar con un medio auxiliar, desplazable, ocultos detrás de una cubierta en una depresión y destinados a la sintonización de canales y, en caso necesario, a la selección de una gama de frecuencias que es ajustable en una posición del botón de presión giratorio diferente de la posición de sintonización por giro hasta alcanzar diferentes posiciones angulares de enclavamiento, y con un interruptor que puede ser accionado en caso de necesidad con ayuda de un empujados de maniobra a través de la cubierta, caracterizada porque el empujador de maniobra es al mismo tiempo un medio auxiliar para hacer girar los botones de presión giratorios.
