Yes there are limit switches for 0 and full.

If you know a type of relay that might work I'd appreciate a URL. Google
searches haven't found me anything yet.

You can probably find a better fit and perhaps even price from a local
electrical controls supplier, but perhaps this might work.

Shop around, there are hundreds of different brands, models and features to
choose from. Many are even programmable now days. You just need one that
will come on for 10 seconds or so, each time you bump it with the switch you
already have - and provide a simple adjustment you can tweak as desired.
