It can be many things, testing it may be necessary to find out.
 
I see silver contact and coated plate of brass/bronze. Eventho im not quite sure it is electrical, as for the silver contact.
But the edges clearly show some brass where it was scratched by dragging it on the ground.

you have nitric acid?
in any case, any scrap miner should have it !!!!
you take it, bite off the contact, throw it in acid. If the contact is made of platinum or gold, it remains intact and will shine brightly. (check the white one with a magnet - it may be a tungsten alloy),
if there is palladium in the alloy it will give a coffee color around the contact.
If this silver dissolves, then you add a pinch of salt and chloride will form.
