Two way wiring

[lemmy]

Hi all

I'm changing a few light switches etc for shiny new ones and it's pretty much swap one wire for another and straightforward so far. But this one has me foxed.

Pix at:

's the upstairs switch of upstairs hall lighting which can be switched on and off downstairs also. There is one other light switch for it further up the corridor upstairs. Do I need a different light switch or has the wiring changed so much in the maybe 20 years since this one was installed?
