Two part wooden BS52 plug with brass contacts The two parts are threaded so they can be fixed together.

The two contacts are brass, with threaded posts and hexagonal brass nuts for the two wires.

A vertical separator between the terminals keeps any strands of wire away from the other side, preventing a short circuit.
