In the last couple of years (roughly since mid-2003 but depending on
station model), the switch design has been changed a little. AIUI the
reed switch is now mounted on a tiny circuit board, this operation
being done under carefully controlled conditions with the result that
there should now be little or no stress on the switch wires. The
little circuit board is then mounted into the anemometer in a separate
non-critical operation. While it's fairly early days yet, the
indications thus far are that the incidence of premature switch
failure is now very low.

Would replacement switches be of the new design? given your remarks I hope
that this is the case.
