Lighting question

So today I wanted to add another switch in a house.

The extra switch would need to now include an intermediate due to it being already 2wY.

now when I took the switches off, one switch the common has just a single sheath core, the L1 and L2 are a 2 core cable L1 being Red and L2 being black.

This is exactly the same in the other switch.

I thought this must mean there is a JB somewhere ? In the light fitting there is 3 T&E, and 1 single cable which goes into the lamp live!

I just can’t understand how this could be wired?

Any ideas?

I'm pretty sure there will be a Joint Box (JB) hiding somewhere under the floor or in the walls. We used a 25kHz live tracker on several occasions to chase around the installations to find all the hidden JBs.

What is this 25kHz you speak of? Also how do they work?
