Intermediate switch.

[Conroy]

Ok so, im following on 2nd fixing from someone else who has first fixed a loft conversation. He's no longer with us.

At the top of the stairs I have an intermediate SW to go in consisting of 2 X 3 cores (intermediate SW with one 3 core going down stairs and another one down the hall) 2 X mains, 1 X load.
Another intermediate SW half way down the hall (2x 3 cores) a switch at the end(3 core) and a switch at the bottom of the stairs (3 core)
I wouldn't have wired it this way myself (not saying it's wrong) but I've never feed an intermediate before with another intermediate.
At first glance today I was like how do I connect that. Any takers?

Commons in a connector block or wago, strapers from 1 of the 3c+E in to one side of the intermediate switch (don’t matter which), strapers from the other 3c+E into the other side of the intermediate switch, Choose a side of the switch and connect feed in and out with one of the strapers, connect Switched line with other straper on same side of switch, terminate neutrals and CPC’s appropriately.

Connect feed to brown of one 3 core, switched live to brown of other 3 core.
Connect browns to common and black/grey as strappers at 2 way switches.
Connect black/grey as strappers at intermediate switch.
