UK How to wire a 3 way switch, the unconventional way

[theshaniqua]

Hi all,

I am hoping someone could settle this for me.

I would like to know if it is possible to wire a 3 way switch, where the master switch is feeding 2 slave switches separately, i.e. rather than going Switch 1 > Intermediate Switch 2 > Switch 3, it goes Switch 1 > Switch 2, and Switch 1 > Switch 3?

Would be grateful for any advice. Thanks in advance!

How would you suggest installing it in my 49 year old system, if required.

Hadn't realized that the intermediate switch had 4 contacts so the attached might be OK.

That’s exactly right @johntheo The intermediate is a changeover switch.

What is meant here by master and slave? How many loads are being controlled separately?

heard the term with varilight touch dimmers. you have a master and 1, 2 , or 3 slaves.
