2 Way Light Switch Driving me Crazy!!

[Marc England]

Hi Everyone,

Ive been having a nightmare when trying to install a new 2 way light switch in my house,

I currently have normal single gang 2 way light switches in my living room, on one of them there is a C terminal, and L1 and an L2, with 1 wire going to C and 2 wires going to each of the L1 and L2 terminals. on the other light switch there is a C terminal and a L1 and L2 and there is one wire going to each of these terminals.

however, i want to replace these with 2 Livolo touch screen light switches, on these switches they have a C terminal and an L1 terminal but then they have a signal A and a Signal B terminal,

Ive tried google and cannot find anything,

any help would greatly appreciated for my sanity's sake!!

Thank You

Marc :smile5:

Hi Marc ........................what do the instructions say ??

 

[telectrix]

you have a standard 2 way switching set up. have you got instructions for the livolo switches. ?

 

[Rockingit]

what you will probably find is that they need a permanent live and neutral in order to work (not able to look those units up at the moment). In which case, the send A and B replace the L1 and L2 (I guess) but you might struggle to make yourself a permanent neutral without doing some rewiring.

@ marc. can you scan the instructions bit of wiring diagram and post it?

Hi

The instructions shows a diagram of the two light switches, on one of them it shows Live going to the L terminal and on the other it shows a neutral going to the L1 terminal and then connected together via the Signal A and Signal B terminal

Hi,

this is the diagram from the instructions

 

[telectrix]

so it seems you will need a neutral wiring to both switches. this is a job best call in a sparks.

No neutral needed at either switch. The 2 core and 3 core between the switches are ample for what’s required.
Give me a few minutes and I’ll knock up a drawing.

 

[telectrix]

just seen the diagram. best call in an electrician.

Looks to me like one of the switches is fed with a permanent live and is joined to the other switch via the Signal A and Signal B (L1 and L2 in a standard 2 way switch) and then feeds the light via the L1.

This would be the same as feeding the common of one switch, joining the switches L1 and L2 with T&E and then feeding the light from the common of the other switch.

Try this

Something like this

Left switch

C = L
L1 = Signal A
L2 = Signal B

Right swicth

C = L1
L1 = Signal A
L2 = Signal B
