Infinite Switch failed, burner would not heat

Removed two screws holding 4-switch panel, drew a simple diagram to assure placement of wires on correct terminals, removed and replaced switch.

Switch works fine, but original knob does not fit shaft of replacement switch. Will try to order new knob, but it probably won't match the old knobs, so range will have one new knob & three old ones. I wish the order page noted that new knobs must be ordered to fit the new style shaft.
