Silent pull switch

[Peco141]

I intend to buy one of the pull cord dimmer light to replace the current noisy on off ping that the current bathroom light makes. 15 month old baby daughter is not it's biggest fan..

I've read a few posts on the site that swear buy these dimmer pull cords however a neutral feed is required to eliminate potential buzzing and a live feed.

Can someone confirm if I have these live and neutral feeds from the picture below before I buy?

If it is the Greenbrook pull switch dimmer - it doesn't need a neutral.

thanks guys.

If it is the Greenbrook pull switch dimmer - it doesn't need a neutral.

If the theory is correct and that neutral elimates the buzzing is it safe to say that a Greenbrook pull cord dimmer does not need a neutral connection and in turn will not buzz or have any other noise omitted and is therefore silent?

The Mrs won't be happy if she thinks there's a wasp in the bathroom when she's having a dip in the bath...

The Greenbrook Dimpull, is not completely noise free but near as damn it!

The presence of a neutral has no bearing on any buzzing noises. They are a function of the quality of the dimmer and its suitability for the load.

For instance, if your dimmer is rated at 200watts and you give it 200 watts of halogen lights to handle, fed through 12v transformers then it will complain. It will be worse if the load is not matched to the transformers (leading v trailing edge).

Personally I have changed my pull dimmers for wall mounted dimmers outside the bathroom door.

Better to buy her a box of T-lights and pour her a G&T.

Don't forget that if you've got an extractor fan you might get problems with a dimmer switch

 

[Peco141]

The pull cord is powering 3x 50 watt halogen bulbs therefore 150 watts.

The problem next is to establish what rate the dimmers are. The product information on Amazon is rubbish. How can I tell what wattage rate the dimmers are?

Additionally whats the difference in DIMPULLSW-C and DIMPULL-C?

 

[securespark]

The DIMPULLSW-C is for a toilet.































































































Only kidding!

Think the "C" comes with chrome cover and the "W-C" comes with white and chrome covers.

It's a bit worrying that you could think you might have a L & N connected to a switch like that.
