It appears that I need to replece the reed switch on my Davis VP1 station
rain sensor as it is was not operating for a time yesterday.

If anyone here has carried out this repair it would be much appreciated if
they could supply details of suitable replacement switch and any other tips
in how to carry out the work.

Sorry Alan, don't have the answer, but I asked it before once and
mislaid it. Please issue again, in nice simple terms. :-)

Alain, these are the ones I was advised to get and used, replaced one
about 4 years ago in my WMII and it's still working (38.8mm last two
days :-)

You can order them online.

Fairly easy to change if you haven't got clumsy fingers like mine. You
will need solder + heater.

I hope this helps.

Before we moved over to Instromet for AWS readings we used a Davis VP that
needed to have its tipping bucket arrangement replaced. The problem was the
same...faulty reed switch. John Dann (Prodata) was able to supply a
replacement...I am afraid the whole bucket system needed replacing and
removing it from the ISS was quite tricky..prizing back the flanges and
hoping they didn't snap.

My advice...give John Dann a ring, I always found him to be very helpful and
quick in finding a solution.

I've done it on my Oregon Sci. gauge. The switch is noncritical apart from
the size so take it apart and get your ruler out. Looks like taking it
apart might be the hard bit for others posts...

Reed switches are delicate, particularly the wire to glass seal. Always
hold the wire in needle nosed pliers between the switch and any bending to
be done. Also use the pliers as a heat sink when soldering. Coat the
repaired reed and new soldered joints with something to keep the damp out.
I use a spray conformal coating but I guess a bit of polyurethane varnish
would do. Coat after testing...

Thanks for the information everyone, I think my soldering skills are just
about up to the job. I just need to choose a decent day.
