Float Switch Assembly

This is a float valve assembly used in conjunction with a microswitch (must be purchased separately) to turn a circuit on or off when a water tank is full. I designed this to work on a caravan on board water tank to automatically stop the fill pump once the tank was full.
Additional parts required are.-
* Microswitch (check hole dimensions and current rating)
* 1 off M3x20mm bolt or screw to fix pressure pad to float shaft.
* 2 off M2x15mm bolt and nut to fix microswitch to top housing.
* Wire / cable to suitable current rating

The assembly requires a 20mm hole to be drilled in the top of the tank, nut to fix assembly to tank is 3D printed.
I've posted a video of the float switch assembly in use on my YouTube channel DTSQUARED. https://youtu.be/e53kfhNFYvY
