There are small drops inside.

Does anyone know where I can get a rotary switch that has 10

I can go down to the local electronics supermarket and find computer
headsets complete with electret boom mike for a few bucks.  However, trying
to find just the microphone and boom with pigtail leads is proving either
horrendously expensive or nearly impossible.

I have a stop watch that has a LCD screen witch I would like to
