I need a rubber backing material for some low voltage electrical
contacts because there has to be a slight give when the contacts come
together, and I was hoping to get recommendations on what kind of
rubber to use. (The voltages will be in the order of +5, -5, +12. -12,
& +24).
I was looking at rubbers made for gaskets and I'm trying to decide
between Nitrile, Styrene Butadiene/Natural Rubber blend, and generic
cork rubber..
Any advice would be appreciated.
Thanks.

Probably depends mostly on the hardness of the rubber. Nitrile and the
blend both come in various hardnesses. The cork rubber may also. I'll
bet the cork absorbs water.

With high voltages come corona discharge, ozone, and the
contact-closure area will give off UV. I'd think in terms of
silicones, just for chemical stability.

Could you explain more about why you need the contacts to "give" when
closed?
You would not want to disturb the wiping action of the contacts.

It seems that everyone else just uses spring-loaded contacts.

if you must use something flexible and waterproof "+1" for neutral cure RTV silicone

It will be a row of 16 contacts and the idea is to make sure that each
contact will mate consistently with it's opposite when the top and
bottom rows come together.
Nylon blocks serve as the supports over which the contacts are laid,
and the I want the thin rubber to go between the blocks and the
contacts. This way none of the contacts will separate as a result of
vibration.
Thanks.

OH ALRIGHT, YOU CAN USE THIN PLYABLE HARD PLASTIC, LIKE THEY USED IN
STEREO EQUIPMENT AND OTHER PC BOARD / WIRE CONTACT LOCATIONS.
IT IS SIMILAR TO THE STUFF USED IN HANGING DISPLAYED PRODUCT
PACKAGING NOWADAYS.

So I gather that you made this contact arrangement.
Usually the contacts are held together by springs and the wiper arm is
spring material and arranged so that the contacts slide as they
contact.
Thin rubber supplying the closure force in quite unorthodox.
