Pushbutton tuning system

Claim 2

A pushbutton tuner module for a signal receiver having a voltage dependent tuner means comprising: enclosure means having upper and lower portions formed for attachment therebetween and providing a plurality of aligned openings; printed circuit board means disposed within said enclosure and including for each one of said aligned openings a pair of electrical switching means each having a spring member with an apex, a light source, and an adjustable resistance; pushbutton means formed for engagement with said enclosure and disposed within each one of said aligned openings, each of said pushbutton means having a bump for pressure engagement with said apex of said spring member to effect latching of said pushbutton upon inward movement thereof and adapted to be slidable inwardly and outwardly within said opening to effect engagement and disengagement of said pair of electrical switches causing energization and de-energization of said light source and coupling and decoupling of said adjustable resistor to said voltage-dependent tuner for varying the tuning of said signal receiver.

Claim 3

The tuner module of claim 1 wherein said enclosure forming said plurality of aligned openings includes a groove extending normal to said openings and a slot extending along the longitudinal axis of each one of said aligned openings, each one of said pushbuttons includes a finger member extending normal to the longitudinal axis thereof and inwardly and outwardly slidable within said slot, and cable means fastened at opposite ends and disposed within said groove to provide engagement with said finger member of a pushbutton moved inwardly of said opening into an operable position.

Claim 4

The pushbutton tuning module of claim 1 wherein each one of said adjustable resistances includes a fixed resistance printed onto said printed circuit board and electrically connected intermediate a potential source and a potential reference level; a threaded metal screw member affixed to said enclosure and electrically connected to one of said pair of switching means; a slider member affixed in electrical and mechanical engagement intermediate said threaded metal screw member and said fixed resistance; a spring telescoped over said screw member and contacting said enclosure means; and screw turning means telescoped over and in engagement with said threaded metal screw member and in contact with said spring and supportedly affixed to said enclosure means.

Claim 5

The pushbutton tuning module of claim 3 wherein each one of said pushbutton means includes an end portion having indicia thereon with said end portion confining said screw turning means within said pushbutton by compression of said spring and said screw turning member extending outwardly of said pushbutton upon removal of said end portion and expansion of said spring.

Claim 6

The pushbutton tuning module of claim 3 wherein said indicia of said end portion of a pushbutton is illuminated by said light source therein upon inward movement of said pushbutton.

Claim 7

In a signal receiver having a voltage dependent tuner, a pushbutton tuner module comprising: an enclosure having upper and lower portions formed for jointure therebetween To provide a plurality of aligned openings; a printed circuit board formed for disposal intermediate said upper and lower portions of said enclosure and extending outwardly therefrom in a direction opposite said aligned openings, said printed circuit board having associated therewith for each one of said aligned openings a pair of electrical switches each having a spring member with an apex, a light source, and a resistor formed for adjustment in resistance values; and a pushbutton for each one of said aligned openings, each of said pushbuttons disposed within one of said openings of said enclosure having a bump for pressure engagement with said apex of said spring member to effect latching of said pushbutton upon inward movement thereof and in slidable engagement with said enclosure and formed for effecting engagement and disengagement of said pair of electrical switches, energization and de-energization of said light source, and coupling and decoupling of said resistor to said tuner of said signal receiver.

Claim 8

In a signal receiver having a voltage dependent tuner, a pushbutton tuner module comprising: an enclosure having upper and lower portions formed for jointure therebetween To provide a plurality of aligned openings; a printed circuit board formed for disposal intermediate said upper and lower portions of said enclosure and extending outwardly therefrom in a direction opposite said aligned openings, said printed circuit board having associated therewith for each one of said aligned openings a pair of electrical switches each having a spring member with an apex, a light source, and a resistor formed for adjustment in resistance values; and a pushbutton for each one of said aligned openings, each of said pushbuttons disposed within one of said openings of said enclosure having a bump for pressure engagement with said apex of said spring member to effect latching of said pushbutton upon inward movement thereof and in slidable engagement with said enclosure and formed for effecting engagement and disengagement of said pair of electrical switches, energization and de-energization of said light source, and coupling and decoupling of said resistor to said tuner of said signal receiver.

Claim 9

The pushbutton tuner module of claim 6 wherein said resistor formed for adjustment in resistance values of said printed circuit board is in the form of a printed resistance affixed to said circuit board; a slider member electrically and mechanically contacting said printed resistance; a threaded metal screw member mechanically and electrically associated with said slider member, said enclosure, and said electrical switches; and a screw turning means telescoped over said metal screw member and affixed in support relationship to said enclosure.

Claim 10

The pushbutton tuner module of claim 7 wherein said resistor formed for adjustment in resistance value includes a spring member telescoped over said threaded metal screw member and intermediate said envelope and said screw turning means.
