Hi,

I have a crabtree patress box for an architrave switch and one end is
marked "top". Is there any reason it has to have this end at the top?
I ask because the top only has one cable entry; the bottom has two and
I would like to drop two cables through the top. Is there a reason I
can't install it upside down?

TIA

Because the switch will be 'on' in the 'off' position? (unless 2 way)
