Changing 3x Old Light Switch

[Brian29]

Hi EFLl, I succesfully changed all our light switch except for Switch #1.

From this...

Old COM Yellow wire (is this live?) to New COM1
Old L1 Blue wire to New L1 1
Old L2 Red wire to New L2 1
Old COM Red wire to New COM2
Old L2 Black wire New to L2 2

Into this:

Followed carefully the connections as per your advice...

But when I switched the fuse back, it tripped??.. What could be the problem?

Thanks for your help

Contactum: Retrotouch:
COM Yellow wire (is this live?) to COM1
L1 Blue wire to L1 1
L2 Red wire to L2 1
COM Red wire to COM2
L2 Black wire to L2 2

Correct.

Switch #2 Old 1 Gang switch to Retrotouch 1 Gang switch:

Old: Retrotouch:
L1 Yellow wire (live??) to COM
L2 2x Red wires to L1
L3 Blue and Black wire to L2

Correct.

No, the Red is the permanent Live; Yellow is switched live as is the Black.

Switch #3 Old 2 Gang Switch to Retrotouch 2 Gang Switch:

Old: Retrotouch:

A Red wire to COM 1
B1 A1 Black wire to L11
B Red wire to COM 2
A1 B1 Black wire to L21[/quote]

Wow thanks for the advice EFLImpudence, forgot to tell, the switch # 1 and switch # 2 (upstairs) switches on and off the light upstairs, so the wiring diagram that you laid out still the same when installing new light switch in switch #2?

 

[EFLImpudence]

Yes.

I forgot to colour the Blue wire, of course, which is also a switched live.

Hello there sorry for bothering you but could you help me out please as I am a bit confused.. I am changing all our bedroom switch aswell (1 gang switch) but upon opening the old switch, the wiring are different and don’t know which one is live. Correct me if I am wrong with the attached photos below. Thanks in advance.

Room#1 (not sure which one is live)
Old L1 Red wire to New COM
Old L2 Black wire to New L1

Switch#2 (this confuses me as it’s different from switch#1)
Old COM Red wire to New COM??
Old One way Black wire to New L1

Switch#3 (another confusing switch.. black is live??)
Old L1/1way Red wire to New L1
Old COM Black wire to New COM?

All old switches above will replace into Retrotouch 1 Gang Switch:

Thank you.

Or maybe not?

The red that is in the same cable as the blue and yellow should go here -

 

[EFLImpudence]

You do realise that these are the two switches -

Not top row and bottom row.

 

[Brian29]

Ok so L2 1 red wire will go to L1 2? I’ll go and try.

 

[Brian29]

Yes like the old contactum switch.. that’s why I assumed the connections are the same

 

[EFLImpudence]

but you didn't do them the same

 

[Brian29]

Sorry my bad. So to be clear before I proceed, is this correct EFLl?

Old COM Yellow wire to New COM1
Old L1 Blue wire to New L1 1
Old L2 Red wire to New L1 2
Old COM Red wire to New COM2
Old L2 Black wire New to L2 2

Thanks
