HA HA HA! *10/10!

Funny how common this problem is -- I also agree with the complaint. I
have a couple of "quiet" ones (what's more, they work with one click,
not a "tick-tock" or rtather "clunk-click" action). *I just took the

I have just e-mailed MK Techical to ask why they are noisy.

I have been told (wait for it!!)

"The product that you have described will make a ‘noise’ when the pull
cord is operated due to the mechanical mechanism inside, this coupled
with the location ie mounted plasterboard on the ceiling will sound
louder."

Amazing! Glad I didn't waste a postage stamp!

I will become obsessive and try switches in shops whenever I see them.
In the meantime a swop with my loft switch is called for when it is
light enough.

Incidentally - I have a transformer for LV lamps and a fan so a
sensor / dimmer is not a simple choice.

This whole problem made me put all our bathroom switches outside the
bathrooms when we re-wired. then I could have normal switches.

The problem is that, to prevent arcing, all switches need to have a good
'snap' action.

Not necessarily - you could use a mercury tilt switch (possibly
actuated directly by the pullcord).

Mercury? These days, in the home?

Well; it's inside a glass tube, you know.
