Wiring a fan isolator switch

[va-it]

Hi everyone,

I hope somebody can help me see something obvious.

I have bought a fan isolator from Trendi (for aesthetic reasons) and I would like to replace the existing one; the problem is that I do not understand how to wire it, because the new switch has a different layout for the terminals. The instructions only managed to confuse me even more.

I have included a photo of the existing switch and the diagram provided in the instructions. Where does each cable go?

Thank you in advance

Is the new one a 3 gang light switch?

Ignore the new diagram.

Label the wires before you disconnect anything.

You have 3 pairs of wires.

On the old switch, they are labelled L1-L1, L2-L2, and N-N.

On the new switch, they are labelled COM1-L11, COM2-L21, COM3-L31.

From the back it looks like one, but the bottom terminals are blanked out. The front though has one single big switch (see photos).
For completeness, here is the link to the product page on the website: http://trendiswitch.com/10a-triple-pole-bathroom-fan-isolator-switch-1130-p.asp (apologies if including the link breaks the rules of the forum)

Thank you, that is very clear and helpful.

Shall I treat your questions the way you think mine should be?

Yes, the instructions are bad, but you have two cables each with grey, black and brown, and I have marked terminals also grey, black and brown, it does not matter brown goes in which hole marked brown, same with grey and black. Does that make more sense?

Thanks @ericmark
I had assumed that this was the way to wire it, but the instructions made me doubt myself.

I have wired the switch yesterday thanks to edecotp's reply, but your response, I am sure, will be very helpful to anyone who stumbles upon this post in future.

the instructions made me doubt myself.

The instructions are wrong. They show the way to wire it if it were a 3-gang lighting switch. They need different diagram for the assembly to be used a s a 3-pole fan isolator. Write and tell them. It won't do any good. but may make you feel better.

Yes, you're spot on, until I saw the picture of the back of the switch, I was not even sure if the switch would work, very poor instructions.
