hall lighting

[Mini1961]

Hi folks,

Trying to work out how this works, 7 metre hallway, 2 ceiling roses, 3 switches 2 at either end two wat and one in middle intermidiate , the roses will be loop in out, so on the first two way switch i have taken a drop for a switch, have looped 3+E from this into intremidiate then to other 2 way at other end, will this turn both on and off

Cheers

Your description of the switch wiring sounds right. The two roses must be wired in parallel so only one of them will be loop-in/out. You use twin core cable from this rose to the switches just as you would for a single switch. Its other end goes between L1 and L2 in any of the three switches. The only wire in the COM terminals of the end (2-way) switches should be the one linking them together.

PS: Don't forget the earths.

For the second light, extend the switched live and neutral to the second rose.
