Are these the old switches where the covers are screwd on by Hand old Bakelite small round thingys ?
, if so that's an issue as potential access to live part without the use of a tool . I would code that as a 2 me thinks .
Funnily enough I'm doing a job in a old hospital witch is now a museum were I am using the old( looking ) bespoke switches on wooden backing fancy
My Mum's house had those switches until I rewired it an I can assure you that they DID need a tool to access the live parts.
The tool I used was a hammer because there were so many coats of paint on them it was impossible to screw to covers off them without smashing them !!!
