Hi,

Is there such a thing as a three way switch? I was thinking it would
be useful for the outside lights:
position 1 off
position 2 always on
position 3 on via pir

Does such a thing exist?

TIA

Yes. However you would probably need to make it out of components
and thus take responsibility for the safety of the assembly.

Having said that I have a vague recollection of seeing a switch that
had two on positions and a central off position. It was in a
catalogue or web site, I saw it in the past week, it was in the
style of normal electrical equipment and that is all I can remember
about it.

PIR lights often have this functionality built in.

Switch in off position = light off
Switch off to on = light in PIR mode
Switch off to on then off and back on within 30seconds = light always
on.

Sorry to hijack your post, but is there a gadget that will electocute SWMBO
if the starts the bloody washing machine while I'm in the shower?

Be easier to do it with two? An on/off and a manual/auto?

Also doable with a two gang switch. One switch is off and PIR on, then
the other is off and on.

Used to be able to get a two-way centre-off, which is what you want. You
might still be able to get one in some gridswitch ranges.

Somewhere I have a gridswitch one. However, it's for the previous
generation of MK gridswitch where the switches had toggles.
I don't think it exists (or would be viable) for rocker switches.

There are certainly miniature toggle switches with a centre off. I have
some. I've a feeling I may have normal sized rockers too. I'll look later.
Either could be fitted to a blank plate if looks aren't important.

I've been waiting for words of wisdom as I also would like
on/centre-off/on switches for lighting. I'd hunted around a bit last
week and wondered if the Supergrid 8000 gridswitch 8024 do? (See
http://www.memonline.com/supergrid.html) But (big but) I've not yet
got prices so it may be they are prohibitive.

May I also ask if it is possible to buy panels to fit bog-standard back
boxes to take Euro size 250VAC rocker switches (of which there seemed to
be a vast range)?

Looks pretty hideous, though. Like 20 year old MK.

Not seen them but you can of course make your own holes in blank plates.
Likely to look better since they can be bought to match your existing
ones. If metal you could almost certainly get a Q-Max type punch - at a
price.

Hi

MK 2 way + Off grid switch

You will need a frame and faceplate too.

My gravity shower has separate feeds to get round this problem. Surrey

MM. need a pair of mains relays to handle any load though.

One sort of thinks that a triac/solid state solution looks more appealing.

Told you to get mains pressure ;-)

Yes they do but it's not the tidiest way of doing things. I suppose we
are creatures of habit and if we want a light on we are used to
flipping a switch; not turning it on and off and on again.

HI
Try a 20a sink/bath dual tank immersion heater switch.
Bit of overkill I know but fits a std single box.


(BTB Dave try reverse psychology ,wait while SWMBO is in shower then turn
all taps on downstairs ) NB get ready to run..

Then it was not designed and installed properly.
