Abstract

Dispositivo a fricción destinado a ser utilizado en auto-radios, en el cual un bastidor soporta un cursor de sintonización de tipo convencional, un botón de sintonización y teclado para la preselección de las estaciones emisoras, caracterizado porque incluye: un elemento capaz de realizar un movimiento de vaivén sujeto en el cursor de sintonización; y un elemento giratorio accionado por el botón de sintonización, estando dichos elementos empujados de manera separable el uno contra el otro para que estén en contacto a fricción y estando sus superficies de contacto mutuo conformadas de tal manera que la superficie de un elemento se acuñe en la superficie del otro elemento.
