The electrician located at the end of our street whom I just had on the phone was talking about schema 3 and schema 6.
Schema 3 and 6 are the Feller switch wiring diagrams:

See here for a pdf

Schema 6 is the cross-over. The other two switches will be schema 3.

Don't worry about the colours of the wires - worry where they are attached to the switches according to the wiring diagram to which I provided a link.

What sort of lamp (make/model) and what sort of dimmer (make/model) do you have.

I refused to pay 300 CHF for a Feller rotary dimmer the other day so converted the feller switch to non-latching and stuffed a Zigbee dimmer/switch behind the wall switch. I can control it dim or bright by holding down the switch and on off by a press of the switch.
I can of course control it anyway I want via my home-automation.

Re: Unclear about electrical wiring in apartment

its not SCH6 but it could still be SCH3. there are enough wires because those switches have bridges in them to supply incoming live to both switches (black terminals are bridged). if any of them have more than one of the orange terminals connected then it isn't a latching switch setup.

there is also a little flip switch on the side that is used to convert switch itself from momentary action (which would be used if you have a relay in the panel) or a flip flop switch.

so easy to tell if you're there - wait for the electrician....

Lamp (which consists of 85x 1.2W LED lamps) and dimmer.

The LED-bulbs supplied with this lamp can be dimmed and this 85 lamps is not suitable for electronic switches. Dimmable with a normal incandescent light bulb dimmer, called Leading edge TRIAC dimming.

Cool lamp!

Looks like it should be okay with that dimmer but no data on wattage of lamp.

This is assuming the dimmer has a push-on, push-off switch (I think all Feller ones are - mine are at least), rather than having the switch at the beginning of the turn of the dial, you can only use this with one other switch.


However (and this is a big one) the circuit can only consist of the lamp, this dimmer and one of your other switches.
The dimmer switch does not have change-over contacts so cannot be used in a three way circuit.

There are ways of doing this but it gets much more complicated.

Yes, the two on the right - you can just about see the picture of a switch and a coil (= relay) on them.

I have one (very old, no longer used) - apparently they used to be called a "Teleruptor" and a Google search for that still gives a lot of hits even for modern devices.

Re: Unclear about electrical wiring in apartment

Thanks. That circuit #24 controls a number of lights and sockets on two floors. How the got it to work only on one light in the dining room, I donít know. But Iím happy they did.
