Light switch

[lasutd]

I've just replaced my old plastic light switch with a new metal one. The light works, it comes on, but it won't turn off. I've tried the old switch back on it and still won't turn off. What am I doing wrong?

wiring it wrong

 

[jimi]

you need to tell us how many wires you got there and waht you have done with them

 

[lasutd]

There are 2 red wires which I put in the top, COM, and a black wire that I put into L1.

 

[Steve]

is this light switched from 2 locations?

 

[lasutd]

No, just the one switch.

 

[breezer]

thats where you went wrong then.

is there anything else you would like to tell us?

its just 3 wires implies you can turn light off / on from two places i.e each end of one room

2 reds and a black - cant say i have heard that one before. i would say connect the reds across the switch, but then what to do with the black . . . ??

How was the old one wired? Why are you messing around with a dangerous voltage with no knowledge?

Stretching your patience beyond its limit, clearly.

Imagine this with single reds to each COM, and red/black T/E linking the two switches.

Hey presto - 2 reds and a black, and wired as lasutd said, it could be on all the time depending on the position of the other switch.

What I don't understand is why he didn't wire the new switch in the same way as the old one - seems like such a sensible idea...

cheers ban, but:

No, just the one switch.

And one hiding behind a wardrobe, or a pull cord he never new he had.........or even a switch that has been blanked off, or the cables pulled out and a JB fitted.......

Numerous ways it can be wired, but BAS's seems the most logical at the moment.
