Hello, and with the disclaimer that I’m no electrician whatsoever,

I had this three-way light switch in my room, which only controlled one light - and its pilot lit when the light was set off. Unfortunately I had to break the wall it was onto because the neighbor had water issues. Left the switch connected to the wires as I thought it wasn’t necessary to unplug it, but the person that fixed the wall unplugged it nevertheless.

The thing is I can’t remember how it was plugged. I can plug hot and ground (at 0 and 1, or 0 and 3) so I can turn on/off the light, but the pilot won’t work in any case.

Here’s a picture of the back of the switch, the numbers at each connector and the little diagram (tried to recreate it at the right side) that is engraved there. Not even sure why it’s 0, 1 and 3 but no 0, 1 and 2 - nor what the little “m” means:

So how can I connect this so the pilot works as before (it’s lit when the light is turned off?) I’d really appreciate any help about this from any electron wizard around here.

      Thank you, I just tried that configuration again - live wire on 0 and 3, and light on 1 - (and viceversa, live on 0 and 1 and light on 3 - wires are really hard to get out of this switches!) but no dice, the pilot won’t ever turn on. Even tried with the other switch from the same socket but still it won’t work. I’m just giving up. Thank you regardless

        Is the pilot supposed to be always on, or just when the light is off (I assume the latter)?

        Are both 0 and 1 always live simultaneously? In that case it wouldn’t be a 3 way switch. I’m not finding info on that annotation, very hard to search, what country / state are you in?

        I kinda suspect pilot should be on the right 0 and light on 3 (guess that m signifies it measures current somehow), unless m actually signifies a separate terminal to use for the pilot
