Hi!

I think I have found a way to increase the reliablity (and make Levak happy :p). I am thinking of taking 26 of these (or similar) connectors: http://www.te.com/catalog/bin/TE.Connect?S=26927&M=PPROP&P=&BML=10576,17560,17553,17559,17770,12594&LG=1&PG=1&IDS=328455,328456,328457,328458,328453,420546,370060,443958,371522,440941,440809,440942,489080,328459,479446,420402,515288,479448,421578,485805&N=11

I will be cutting slots in the PCB at the connector spot, so the spring part fits inside the board. With a board thickness of 1mm, the spring would have 0.6mm to touch the contact (should be enough I think). They will be soldered upside down on the bottom. (I know this is a bit hard to explain. I'll try to draw my idea quickly.)

Farnell will probably have something that will fit. Head over to farnell.com and search for connectors. Enter some specs of the connector.

Been there, done that... It's a really strange connector type! But I think my new idea would probably be ok...
~~I'm going to make a little drawing of it so I can explain it.~~

EDIT: Here's a little drawing (it's pretty hard with a mouse :p):

Hey, I might buy one. It looks like it could work!

Thanks! I will try to redesing the board with the new connector idea soon. When this design is done, please PM me to place your order :-).

Hi Debbor!

Could you please contact me via email?

Ooh, count me interested! My home made ones are getting more annoying to fit on snugly every time. Looking forward to seeing the final product.
