1. In combination:
- (a) a microwave circuit including;
a first wall having an inner surface;
a second wall spaced from said first wall and confronting said inner surface thereof to define a microwave cavity therebetween, said second wall having an outer surface;
circuit component means having opposite ends, one end of which projects toward said inner surface of said first wall, another end of which projects outwardly of said cavity through a hole in said second wall; and
(b) a circuit board secured with respect to said microwave circuit in overlying relationship to said outer surface of said second wall exteriorly of said cavity, said circuit board including;
a cantilever arm portion and a remainder portion, said cantilever arm portion having an inner end and a distal end, said cantiliever arm portion integrally connected to said remainder portion only at said inner end, whereby said distal end will deflect and said remainder portion will not substantially deflect when a deflecting force is applied to said distal end, said circuit board being positioned relative to said microwave circuit when secured with respect thereto, such that said distal end is positioned atop the circuit component means and in contact with said another end thereof so that said component means provides said deflecting force to thereby deflect said distal end, whereby said distal end cooperates with at least said first wall to maintain said circuit component means one end in contact with said inner surface of said first wall.
