Another Light switch question

[jmc45]

Hi All,

I'm currently in the process of adding an additional light circuit to a workshop. Currently the workshop has a single light circuit with a red and black wire attached to a single light switch. (See Diagram below)

I've added a second wiring circuit to add a couple of spot lights at the back of the workshop and plan on changing the light switch to a double switch. I'm not sure how to wire the second switch is it like below?

Thanks for any advice.

No, if that cable marked as "new circuit" is running to the new lights, then you can't just connect it at the existing switch position as there's no neutral present there at the moment. You'll need to pick up a feed from elsewhere.

Draw the circuit to your new light and see what happens when you turn on the switch.

No. You need to pick up a feed from somewhere. Then either junction box or loop in method. If unsure get a spark in.
