Can someone advise on the wiring of this switch please

[Rsian]

Hi all, hope someone can help.

I am replacing a very old MK grid switch with a varilight one and am in the process of re-wiring.
The old 6 gang grid had no labels on any of the wiring so I am doing a like-for-like swap, but the last switch I cannot figure out.

Can someone tell me from the diagram below how the varilight switch should be wired to the neon from looking at the MK one?

It is wired as a two-way from an upstairs bedroom to the downstairs living room.

Thanks.

Wire it the same, I suppose. Is the varilight a two-way switch?

It is wired as a two-way from an upstairs bedroom to the downstairs living room.

Why have you a two-way switch from living room to bedroom?

Also, what is the neon for?

The neon shouldn't be wired to earth.

You should wire the new switch the same way as the old one.
So identify the common L1 and L2 on the MK switch and swop the cables to the new switch using the same colour and terminal codes.

If there are no codes on the MK then It would appear that the bottom red is the Common and yellow is L1 with blue L2.
The neon would be connected as per the old MK switch which appears to be from the blue L2

Although the neon will likely work connected to earth any leakage to earth can cause problems with RCD protection and I would not want to wire that way.

Thanks all, l1and l2 other way round but all good now.
Neon - this is how it was wired when i got here, just re-wiring it back up the way i found it. If there is a safer way of wiring then let me know, the guy here lived here before eas an electrician though.

I just wondered what it signified.

The way it is connected it would only light when the adjacent switch was in one of its (two-way) positions but the room-light may be either on or off.

Nevertheless it should not be connected to earth so if it doesn't do anything disconnect it.


Also, just curious, why the two-way circuit from bedroom to living room?
I have just thought - is the staircase in the living room?

It's for creating live-earth leakage.

Seems a strange way to have wired the neon. I can understand wiring it from the live feed to earth, to help locate the switch in the dark, though.

It is for a floodlight in the garden. Can be switched on and off from the living room or the bedroom.
