New switch is different - how to wire..?

[bobpants75]

Hi there,

Bought some new lights energy saving which means dimmers no longer work...grrr... never mind

So bought a new switch but have a slight different in the holes at the back of the new switch.

The old one has switch 1, Com, L1 & L2 & switch 2 Com, L1 & L2

The new one I got has switch 1, Com, L1 & L2 (OK), but switch 2 has 4 terminals not 3 = L1, L1, L2, L2 & No com

Can I still use this please & if so how should switch 2 be wired where I have no com now..?

Thanks in advance

Nick

Looks like the new switch has a terminal for an Intermediate switch (marked INT). Did it not come with a wiring diagram in the box?

The second switch seems to be an intermediate arrangement.
Some intermediate switches terminate differently to others.
I would suggest connect the one way light to it.
But connecting Top L1 as com and bottom L1 as L1, should give you an open/closed switch function. (or top L1 and bottom L2)
You may need to swap and change the connections, to achieve the function with rocker switch in correct position on switch plate.
Regardless of what configuration you use on the one way circuit, it should not blow/trip the fuse.
If you have continuity test meter, you could test the switch connections to see how they are configured, before connection.

But he didn't know it was an intermediate switch did he, hence asking? I'm sure now that RJM2K has explained that, he will refer to the wiki

1:

2: There's always the approach of LOOKING in the Wiki to see if there's an answer, as per the request at the top of the forum.

Hi all

Thank you all for your replies and I wasn't aware what the INT meant so it all makes sense

Thanks again for all your help
