KEMO Electronics (germany) make these items. They have an interesting
range of
small modules with various functions. Have a look at their web page:

They are wholesale only, but have distributors around the planet.

This should be the best solution, but (up to now) they don't answer to my
email...

Because they are strictly wholesale only, they may not reply. In the past I
have had a reply which directed me to the distributor here in Australia.
