Microswitch Float Switch

Float switch that uses a microswitch and a ping pong ball (which is preferred, but can be replaced with a PET bottle with the appropriate files).

Desired water level can be set using pole extensions.

REMEMBER TO PRINT WITH THE "SLICING TOLERANCE" - SETTING AS "EXCLUSIVE" as always with threads and mechanical parts. Personally I've never had a reason to have it set to anything else.

You could probably print everything in one go in 12h or less but I'd like to recommend printing the pole and the poleguide at higher quality to minimize friction.

The inverted base part exists because in my bucket I already had my float valve https://www.thingiverse.com/thing:5485378 so it was not possible to have the pole in the middle of the bucket due to the bottle. The inverted version places the pole near the wall, and the switch farther out.



To mount:

Pop the ping pong ball in it's hand and attach it to the pole.

Screw in the pole guide, screw on the nut on the switch holder a
