Went to a house the other day where operating a plug-in liquidiser in the kitchen triggered a touch dimmer with r/c (operating a light in the adjacent room) to switch on.

:eek:

Please, has anybody got any ideas why?

Was the remote control for the dimmer in the liquidiser?! :LOL:

That would explain it.

Otherwise, no, I can't explain it, those dimmer remotes are infrared aren't they? If they were RF then maybe you could play the interference card...
 
Could be brushes arcing on liquidiser causing some of form interference and/or spikes .

Most are class II so won't have an earthed casing

Put a radio near liquidiser when it's running soon see if it's chucking out EM.
 
The dimmer thinks its touch plate has been touched when equilbrium between touch plate and the sensor in the dimmer is disturbed.

The liquidiser motor's in rush current is probably causing a transient dip in voltage, possibly with a capacitive induced "bounce" on the earth wire that reaches as far as the dimmer's back box. The equilibrum between dimmer/sensor is disturbed and the dimmer activates.

It's a special safe liquidizers, it knows that you should not be using it in the dark so it turns the lights on :D
 
No earth to the house.

There is a fault in the liquidiser L>E and also in the light switch SW>E

Switching the light on should also operate the liquidiser :LOL:
 
There is a good Ze. Also good Zs on lighting & socket.

Operating the dimmer does not switch on the liquidiser (much to my utter disappointment).

Liquidiser is Class II.
 
As DESL says, try placing a radio next to it to see if it is chucking out RF.
 
as said its a spike.

try it in another socket to see what happens

That reminds me, I derive some amusement from the fact that that Bosch drill chargers seem to have some kind of design flaw where they'll emit enough radio frequency interference to disrupt an FM radio nearby, its funny watching the brickies on site adjusting the aerial and complaining about the snow messing with the radio signal :LOL:
 
It did not seem to operate the switch in other sockets, but having said that, when I returned it to the socket it did operate the switch from, it didn't do the same again.
 
Bad connection in the origanl socket?

Arcing causing spike or EM interference - just a thought
