Help needed: biased/momentary light switches?

Nov 11, 2017 35 Replies

I want to replace the two biased architrave switches that control the garage doors with a standard dual switchplate, but can't find any that have the usual white rocker but are momentary action (biased off). Does such a thing exist? If I can't find anything, the fallback is to get an MK blanking plate and fit a couple of push buttons to it, but I'd prefer it to look like a light switch.


One way would be to use a grid plate with two momentary press switches, e.g.

is a two (or more) way yoke and front plate.

You'll likely have to go to a grid switch system. See TLC, etc.

Thanks, I hadn't looked at those.

I prefer the Scolmore minigrid

One CMA402 and two MD004WH

And maybe a plastic backbox

Now the further thought occurs. Would a mid position switch work? eg a MD075WH in a single module?

I am not sure if the OP has multiple garage doors and a switch for each door or one garage door and one switch to open it and one switch to close it!

K4878PWHI from MK any good?

Thats a single and so far I can't find a dual.

Google grid switches and use a doorbell push Eg:-

There are two doors. To operate them the relevant switch needs to be held down and the direction toggles with each operation. A DP centre off switch on its side would be good (a SP centre off switch might be OK but I need to open up the control box to check). Thanks!

You've done better than I did.

Bell push achitrave switch - MK used to make them.

Yes - MK Grid and GET Grid both have retractive centre off rockers:

Several makers still, as you say search for 'architrave push switch' and you should find some. I bought one recently from Edwardes Electrical.

That's true but my message started with: "I want to replace the two biased architrave switches ... with a standard dual switchplate"

Thanks, but what contorted version of English uses "retractive" to mean "biased" or "momentary"? (Walks off, muttering into beard ... )

Must admit I'd not seen the term before either. Momentary or fleeting or non latching are those I'm familiar with.

Which was ambiguous, I thought you meant a standard dual *architrave* switchplate, even though I didn't know if such things existed.

Everyone in the electronic engineering world I think :)

Not everyone - I have an Electronic Engineering degree (but from the "pre-Chinglish" days) ;-)

I'd say it's rather new being used for this purpose in things like the TLC catalogue. Of course it's not a bit I look for that often.
