Have you asked for a Sample from this manufacturer? Not necessarily in the exact size but it would be smart to test one ahead of time for quality if possible
Just something they already have in stock of the same material if possible to see the plating, finishing, test resistance and stuff. Make sure it sits nice and flat and has a good top with bounce.
@tatasal, this is only an interest list. If there is enough demand and the samples I will order are good and very low resistance, I will buy the complete 1000pcs and ship them to everybody.
No the prices do not include shipping. The max INTERNATIONAL shipping price should be at max 8$, and probably lower, as that is only an estimate. I will try to find a way to make shipping as inexpensive as possible however.
My goal is not to make a profit, but get the best springs possible to everyone. Even if I have to pay a bit of the shipping fees out of my pocket.
@contactcr, I have asked for 10pcs of the Beryllium springs for 20% of the price we have agreed on. If everything goes well, then the group buy will begin, and not the interest list only :laughing:
@giorgoskok, actually, 7mm top is about perfect for all scenarios.
I based my springs upon the BLF Q8’s springs, but made the bottom diameter just a bit smaller for universal compatibility with all switch board, and top a little wider for as much contact area as possible on the cell.
