description abstract	Abstract: Palladium is a particularly efficient catalyst for the formation of polymers. Palladium in the potentiometer wiper contacts on the Voyager Photopolarimeter Subsystem formed a frictional polymer that prevented the stepping of both the analyzer and filter wheels. Catalytic material, including palladium-containing substances, should not be utilized in designs for sliding wipers, relay contacts, etc.
