It would annoy me incessantly to have a two gang switch with only one

It was like that when we bought the house and have had too many other
jobs to spend time on it. Easier for me just to replace the switch
bearing in mind I dont know yet if both switches are connected.
If they are I will try and trace the `dead` one.
Maybe it was for an outdoor light or something. Previous owners done a
lot of DIY and they owned a light company :-)
I am slowly replacing their halogens with LED.
Lounge has 12 x 60w, kitchen 13 x halogens.
