I don't know how or why but I don't seem to have come across it. I guess
I could try to build one but it'll help if you could give me a link or
reference to it.

Well, I can have a go at it. But really, with this pressure sensor
thing, limit switches would soon be obsolete. For you can sense the
pressure (using a light sensor watcher in RCX code, for example) and
shut off the pump motor at whatever level of pressure you require. Going
hi tech all the way, y'know!
