ABSTRACT:
A panel-funnel spring contactor for a projection tube features a keyhole for mechanical engagement with a stud standing on the anode button. Instead of relying upon a leg extending onto the funnel coating to press the contactor against a retaining head on the stud, the present design rolls the leg under the keyhole and extends the keyhole slot into the leg to allow the leg to rest against the upper surface of the anode button and bias the contactor upward against the retaining head.
