Translucent "lollypop" Stationary target switch blades for many Pinball machines. These have a 1 x 1/2 inch oblong face for use with existing target brackets or in target bank mechanisms.
Face is pop riveted to the copper switch blade.
The best reference I've found for replacing these target blades is here on pinside. Not 100% applicable; but should be enough info to facilitate your swap.
