I'm happy to see a DIY version of what can be purchased from WCP.

I haven't used them, so I'll let somebody else comment on actual usage, but the reason 971 developed the sensor is because they found that regular mechanical limit switches accidentally triggered. They are essentially made to replace limit switches.
