Looking for HP 9810A keyboard springs

[Curious Marc]

Springs are a notoriously annoying. In small volume they are very expensive or hard to find. In high volume you basically have them wound for you and they are very cheap per unit, if you make a ton of them. Not much in-between. In the US I have used both of the below for stock springs with good luck:

Hi Guys,

 

I've got an HP 9810A that has been stored in sub-optimal conditions by

a previous owner; a lot of the keyboard springs have rusted away, so

I'm looking for a replacement. These are about 15.5mm outer diameter,

0.35mm thick wire, about 10mm high when uncompressed, and have only

about 1.5 turns of wire.

 

Any pointers would be appreciated!

 

Camiel.
