Old Mk Keyswitch ?

[SLIPSHOD & SLAPDASH]

I need a key, or a picture of one for this old MK  keyswitch. The normal 'fishkey' does not woork nor does a few other makes i have. No part number on the switch. I have about 40 of these on one job





I even tried a similar looking plastic key used to unlock toilet roll holders, it fitted but did not work.

The MK 3405 ZIC   does not fit

I also tried a small driver & failed.

Never known any other MK key than the "Fishtail"  Slippery.

There is a bunch of keys in the van , I'll take a look tomorrow,  see if theres an older MK.

Thanks but no, thats the same key as the present one. The pic i took isn't that good. Its the same fitting and physical size as the one in the link but the keyhole is twice (if not bigger) the size. I am guessing from trying different keys the prongs are deeper and further apart than the current type.

I have seen this type before, with the hole in the middle but never tried to operate one.

have you tried more than this one switch?

it may be broken.  :C

ah, missed message, I'll have a look in the box tomorrow too.

 

[SLIPSHOD & SLAPDASH]

Yep, tried 3 or 4.

It always amazes me how these keys go missing. I do work for  a charity they have a mixture of MK MEM and a few other makes but nobody knows where he keys are. I did buy a few MK  and MEM through the wholesalers but no doubt they will go missing again.

A customer asked me to supply 10 spare keys a few months back. The extra ones i fitted were MK but some oddball make in the rest of the building ( about 6)  had to be changed as no keys were left.

I may well be wrong ( see wife for details )....... But I think the key is more like a T shape, where you put the key in horizontally and rotate it a quarter turn and then operate it as normal

.......have I got one?

No sorry

Just..........

MK catologue only shows the 3405  .

Don't think you 'll get one from MK  TBH .

Are those switches from the 1950s  ?

Think you'd need to change them all TBH !!

 

[SLIPSHOD & SLAPDASH]

I am estimating 1960-70's.

Checked the van Slippery , but no strange ones , just C/tree,   Click and the modern MKs. 

Ebay have the old style MK grid range Key Switches C/w key  @ £12  I think it was .

A small saving by keeping the original plate & grids.

When they went to Grid Plus the key stayed the same, so this is prior to the grid before Grid Plus, so before 1970.

I don't think I've ever seen one pre 70.

You could try the British Museum...Archaeology Dept. 

 

[SLIPSHOD & SLAPDASH]

Ha Ha, If you look at the pic its still the standard grid that was used up to the MKK range, just the key hole opening is larger. There is at least 40 on this job and most are on the ceiling

 

[kerching]

Just a thought.....could you 'sacrifice' one of the existing units.....ie smash it to pieces carefully. Then see what the key. Would have looked like/ method of operation. Then make one or two of them ( posting pics on here of course ), its most likely only a piece of wrangled tin anyway. That way you only have one NEW non standard switch on site

I would be tempted to do this....as I like pratting about

.....just. Inbieber

 

[SLIPSHOD & SLAPDASH]

I had thought about that. Have sent an email to MK tech dept and eagerly await there reply that although may be very nice will be of no use.
