From an Existing "two-way Switch" to a "three-way Switch".

For a while I am trying to
create a third switching point for my existing two-way switch at home.

At the shop they told me that additional cable to the third point is necessary. In my case it’s very difficult do this, because there are no cable traces to the third point and making those would be a hell of work.

So I thought of the wireless switching assortments of KlikAanKlikUit:

These products aren’t cheap and I didn’t want to replace the existing two-way switch.

Materials:

Switching element and receiver: AWMR-300

o 30 Euro

Wireless Switch: AWST-8800

o 20 Euro

Three-way switch circuit (zoomed in).

All the needed materials are small enough to fit in the connection box of the lamp.

Everything is tested and is working just fine.

This solution isn’t cheap, but a lot easier than adding a new cable.

Cheers.
