Two way lighting not working

[peter m]

Not possible, they likely pulled out when you removed switch View attachment 418388 there must be three connections for two way switching to work.

Sorry the picture not as intended, the at moment empty terminal will have the unused wire either red or black from two core, and the blue from three core.

Those wires that are wrapped with electrical tape were not connected to the switch ,still 3 wires in the switch do the others were obviously not required

Have it your own way, but it will not work.

The blue and black were wrapped in electrical tape and were never connected to the switch, there are still 3 wires in the switch and there 3 wires in the downstairs switch

So what u are saying if the 2 out of use cables were in the switch that would be a total of 5 wires but only 3 downstairs

In your picture above ,post no.8,( with the 2 red and 1 yellow wires connecting to a new switch) check the wire going to the com terminal.

Did you miss my above post ? I can't tell from the picture, it's not clear enough, but the wire appears to go where the screw is ??

View attachment 418384 Wired as two-way, note the red wire is in com. View attachment 418387 With this one the black and blue have come out to the terminal.

They have not come out the terminal as they were taped up and not used ,still leaves 3 connections without those taped wires and also only 3 downstairs

As it isn't working, it can't be correct.

Can you post the photos you took before you changed anything.

I did at the start of the thread

As Eric has tried to tell you these wires were in a terminal before you removed the faceplate of that switch. Perhaps the screw wasn't tight but they were in the terminal and they were making a connection.

They were not they were taped up as not in use

They were not they were taped up as not in use

So how come only 3 wires downstairs you wouldn't have 5 wires going into the upstairs switch

 

[pcaouolte]

They were not

Ok, I'm out.
