These are 2 old cast iron and brass switches by Artic.
Stamped on the back is M9120B/1
They are quite heavy and they measure 5 inches in total length, 3 inches wide and 2 and 1/2 inches deep.
The main body is cast iron but all the screws and fitments are brass.
I've no idea if they work or even what they were used for but with a good clean they could be very decorative
