HP switch parts
This page details known switch types in Hewlett-Packard keyboards, as found in HP’s service manuals. In most cases, the manufacturer part numbers are not known, but the series details can be discerned from observation. In a few cases, the equipment was NSN-registered and from this the manufacturer part numbers can sometimes be determined.
