intermediate switch

[electric will]

I got caught out once on some apartments, I'm starting to wonder if I was coming in one switch and out another.

It will work with any number of intermediates.

PS I edited my post

Tony your drawings show that if both 2 way switches are switched active the the intermeadiated switch becomes obsolite, ie it does not switch either on or off

I'll think about it more tomorrow, when I had the problem all seemed ok till one switch was in a certain position, I remember a switch was taking my live away from L1 where I needed it.

The drawing is correct,meh intermediate reverses the poles, if it's easy to draw one with two more switches please do

I'll leave you to sort out the switch combinations

Have a close look and then try to tell me it won't work.

The picture with five switches does seem to work, I did have my switch wires coming to the center one. When I did it my circuit worked till one switch was in the wrong position, I'm sure it wasn't just a case of say common being in L1

There are 37 combinations with 5 switches, 33554454 with 24 switches. I'm not drawing them all out to prove it to you!

I believe you it's just bugging me as what I did in that apartment.

Just looked at intermeadiate change over contact positions and yes you are correct Tony
good job my plant designs are always in singles...lol

This works for all combinations ie 8 switch combinations per diagram (2 to the power of 3 per diagram)



It may not suit peoples conventions but it works
