Push wire terminals.
The BC Unswitched Lampholder is a standard lampholder used on table lamps. It does not have a switch and comes with a 10mm thread in the cap or base to fix to a 10mm stud. The Black BC Unswitched Lampholder has a cap that snaps onto the body so it does not cause the wires to twist.
The terminals are Push Wire and not screw type so the wires must be soldered or have ferules fitted to make a single solid wire.
Comes with a shade ring for shades with 30mm diameter.
