Changing from one-way to 2-way switch

[budbud124]

Trying to change a switch from 1-way to 2-way. Wired like the attached it doesn't work at all - any ideas? Thanks

So the switching was originally one way with a single cable at the switch, you have added the three core and earth cable?
Need a clearer pic of the switch terminals so we can read them.

Nicely notched Grey conductor.

They all need redoing once the correct terminals are established.

L1 is to the right as you look at the pictures with L2 to the left and COMMON at the other end.

Like this neither switch works - change the blue and brown from the light and it stays on all the time.

Will do!

Yes. Just added the three core and earth. Both switches are the same - L1 to the right on pic, L2 to the left and COMMON at the other end.

Have you tripped an RCD in the consumer unit
I had somebody call me a few weeks ago with a similar fault and they had not realised they had tripped the RCD

The wiring of the switches is correct.
The execution of the wiring is extremely poor.
A short length of brown sleeving is required on all sheathed wires except the brown ones.
Green/yellow sleeving is required on all bare earth wires.
There must be no bare copper showing outside of the switch terminals.

No. RCD not tripped
