Wall switch query

danrv

Hi
I have these switches on my living room and conservatory walls that don’t appear to do anything.
Property is 1970s, all electric with warm air heating.
Any ideas appreciated.

They look like electric storage heater switches to me.

They could have been for anything (and not necessarily storage heaters). Presumably they are now redundant, but again that's simply speculation at this point.

Thanks.
I was thinking that and would be useful as I’m considering fitting some storage heaters as the warm air heater has stopped charging (have posted about this in the heating section).
The warm air unit has it’s own circuit with switch but nothing on the main board for these.
There’s this large switch in a separate cupboard but not sure if it’s anything to do with them.
It has the same ‘MK’ branding.

They are fixed/final connection units aka fused spurs with flexible cable outlets.
Whatever they fed has probably been disconnected but the mains feeds to them may still be live.

Do the red neons light up? Are there fuses in the fuseholders (you need a screwdriver to release the holder to check)?

Are there any fuses/circuit breakers in any of your consumer units that are unused (switched off) or labelled in a way that might give a clue as to the function of these switches?

Room and /or water heaters are commonly fed from such - but also fridges, washing machines etc.,. can be.

I had one home where a switch like that (without the flex exit) was used for the loft light. The neon alerted you to it being on once the hatch was closed.

Thanks for the reply.
No fuse in the living room one and no neon lights. I’ve just noticed though that there’s a lot of holes/rawl plugs evenly spaced around and above the living room switch. Possibly used for a storage heater but no idea why as there’s ducted warm air installed.

Above the conservatory switch there’s two hooks.
This used to be an outside wall as the conservatory was added in the nineties.
There’s four fuse spaces labelled ‘spare’ on the circuit board but not sure if these were used
for the switches.

They'll be for top up heating.
