Wiring Lampholder - no terminal blocks ?

[rideforever]

Can someone help with this, it's a new e14 lampholder apparently but no terminal blocks so how is it wired?
It is marked N and L but haven't got the foggiest what to do.
Been jamming the cables into all the orifices ... is this some newly invented c*** I don't know about ?
Anyone know ? Thanks

Probably need to stick a screwdriver into the little slot to release the silver spring, push the wire into the adjacent round hole, remove the screwdriver and check if the wire won‘t pull out of the terminal easily.

Strip wires so the copper is straight and shove it into one of the round holes.
These things are one time use - don't expect to be able to remove wires after they have been installed.
