Matrix-12 / Xpander - switches replacement?

Matrix-12 / Xpander - switches replacement?

2010-07-13 by mirror_saw7778

Looks like I also need to buy new switches for my Matrix 12, a few of the buttons are completely dead and attempts to clean them are not working. The little removable rubber membranes inside are damaged (rotted). 

Does anyone know where I can buy some replacement switches? I checked http://www.vintageplanet.nl/ but he does not seem to have any, nor does ebay.

Well,- I´m searchin´ ...

Original is Marquardt Switch 6401 which seems to be a discontinued part.
I measured my original switches and what eventually comes close most or will fit is the actual Marquardt Series 6425 Keymodules w/o LED and Keycaps for Keymodules 6425, Series 826 ...
These caps are available w/ printings (for the numwerical keypad p.ex.) and w/o printings, grey colour and 16mm spacing.
Download here ...
http://www.marquardt.com/docs/index.aspx?id=23496&domid=1035&sp=E

Marquardt standard switches overview
Marquadt standard switch catalogue
(both english and german langage available)

... and look yourself

unfortunally, there are no technical drawings in the catalogue and up to now I´ve found no dealer to buy one sample to compare w/ a original.

It would be great to have a guy here in the group who´s able to do more accurate measuring w/ his Xpander/ M-12 than I did,- and to get the tech drawings it might be necessary to organize a group buy before asking the manufacturer I fear.
I doubt the company would sell a single or only a few items.

Unfortunally, my technical english isn´t that good to describe the exact measurements of the originals here but maybe someone else could do,- I hope.
There are the contact pins, their separation distance (5mm) and their horizontal position (don´t know how to describe without a tech drawing, it´s somewhat special in this case), the overall size of the switch (16x16mm),- mounting pins and their separation distance (14mm) as well as their horizontal positions (diagonally: left upper corner /right lower), the separation distance of the caps mounting pins (8mm) and horizontal position,- and height of the switch (9mm).
I used a sliding caliper but won´t guarantee the precision here,- it was not so easy w/ the built-in original switches .

It would be great someone would double check and eventually upload a tech-drawing of the original into the files section ! - But next is to get a sample and/or a tech drawing of the replacement for a comparison.

O.T.:

I have the same prob w/ a Oberheim XK, have all the values but don´t even know the manufacturer of the original switches because it´s nowhere documented, so it´s much more tricky.

Hi,
You can try to contact Doug at KICS USA (kicsusa @ aol dot com), he still had some switches 2 years ago, I was able to order some from him in... 2007.

See my message about it:

Thank You!
I just received some switches from Doug. Nice and easy transaction! 

Now all I need is a replacement encoder and I will have a 100% working Matrix-12!

Congrats !

For me, that´s weird ´cause I contacted him too because of the switches after reading the message below and got no reply :-(

I´m not sure about the encoders but I´m intersted too.

For everyone here in the group:

Today, we soldered a sample of:

Marquardt Switch 6425.1101 into my Xpander.
It\ufffds 100% pin and form factor compatible and fits perfectly !

http://www.marquardt-switches.com/tact-and-key-switches.html?&tx_productkatalog_pi1[mode]=detail&tx_productkatalog_pi1[modifier]=0&tx_productkatalog_pi1[value]=6425&tx_productkatalog_pi1[pointer]=1&cHash=15e3636755

The Oberheim switch top covers/caps don\ufffdt fit (not mounting pin 
compatible),- so one has to buy switches (no LED) and related top covers 
in black as well as the numbered ones for the keypad, the + and - as 
well as the orange one.

I germany, you\ufffdll get everything at Conrad
http://www.conrad.de/ce/de/?insert_kz=NA&hk=SEM&WT.srch=1&gclid=CKfIr7OEv6MCFVQq3god63UngA

and here

In other countries please look for dealers in your region.

good news for me and eventually for y\ufffdall too

Three Cheers for PeWe !!!  
Man, thanks much for figuring all this out. I know it's been a major PIA for 
many of us.

Best Regards

Karl Schmeer
