Dimmer Gen 4 wiring UK switch with no Neutral

  • Apologes in advance if this has been already been covered on the forum but, despite many attempts at searching, I have not succeeded in finding an answer.

    I want add a Gen 4 dimmer to the most simple UK scenario possible, which is a switch with a live supply in and the switched supply going out to the light.

    Presumably, the Dimmer needs to be connected between the switch and the light (2 wires from the switch and 2 wires to the light) but, I can't identify a diagram of this set-up.

    I hope there is a solution to this.

    Can anyone help?

    Thank you.
