I've currently got a dimmer switch which I'd like to replace with a standard 3 way switch. It looks like the following:
I've actually gone ahead and replaced the switch, which I subsequently had to revert back to, as while the light at the new switch worked fine, I found my basement lights didn't work with the new switch. However, putting the old switch back and everything worked.
I connected the new switch as follows:
- Where the red wire is (connected to single wire), I connected to the common terminal on the new 3 way switch (black terminal)
- the yellow and black wires were connected via a wire nut to 2 wires, I've connected them each to a traveller terminal (brass terminal)
As mentioned, this works for the light switch in question, but also kills the basement lights i.e. switching that switch doesn't work.
