3 cable switch wiring issue

[dyingfromdiy]

All,

In the process of trying to replace a two gang switch plate, with one 1-way switch and one 2-way switch.

There are 3 cables in the box. 1 cable has Blue, Yellow and Red. 2nd cable has Black and red, as does the third cable.

If 2-way is set up as standard using cable 1, with yellow and blue in L1 and L2 and red in C, then there is no response.

Only thing that seems to work is if both reds from cable 1 &2 are in C together and then it will not switch off.

Any thoughts??

Have a look at this

There's a picture of a two way switch a few posts down.

The two way switch needs to have the three core ( Red Yell Blu ) and one of the pairs wired into C, L1 & L2. Then the other pair is wired red to C and black to L1 on the other side of the two gang.

Red is used as the common in the diagram, but sometimes yellow is the common.
