I use different type of "waterproof" switches. Non of them is waterproof on
itself, I have to make them. Sometimes I use a normal flat push-button und
glue a flexible cover over it, like Michael, and best for the other side is
to glue it completely with Sika or 3M 5200, after you connected the cable. I
tried an empty 35mm film container, like Michael, but Epoxi-Glue and Sika
failed and it never get really waterproof for longer. Maybe a question on
the material the film-container is made from.
There is a toggle-button on the maritime-market, donīt know the name. You
screw it into the wall, and screw a thick plastic cover on the wet side,
then it isnīt ready for submersible but a good start. Put some Sika around
the cover and then ist is absolutely waterproof. But this kind of switch
isnīt so practicle. Too long, so I only use them in more hidden parts in my
kayaks.

Best wet sitch is a magnetic one. Solder a reed-contact on a cable and put
several strips of shrink tube over it. Each one let stay a little bit over
the reed-contact in empty room, shrink it and fold the empty part on the hot
shrink tube and place the next one over it, after few strips it will be 100
per cent watertight. then check out which side of the reed is the
"switiching" one and glue it inside your boat and place a magnet on the
outer side that way, you can pull it on the reed-contact and only YOU  can
do so and no wave! Inside your compartment you have to connect Battery,
Reed-Contact and bilge-pump (or what ever yo want) on  a relay and place all
this stuff inside a (thight) box and ready. Lots of work but waterproof and
you need a relay, otherwise the high Ampere-stream wil cause problems on
your Reed-Contact, its only made for low Ampere-power.
