Wiring 240v spotlights. to existing switch

[dmills27]

Hi,
I have recently had an extension built and wanted to add some mains powered spotlights to some shelves. The lights are very close to the existing light switch so I was hoping that I could replace this switch with a double and use it to switch the spotlights. The spotlights only have a live and neutral; is this possible to do?

Thanks!!

What wires (how many, what colour and what they are connected to) are currently at the existing switch?

Blue (l1) Yellow(l2) and red (com)
Thanks

These are all connected to the switch, it is highly unlikely there is a neutral available at your switch. It will not be possible with your current set-up to do what you want to do.
