Summary

This is another part of my project "water cooling" for my Delta printer.

The idea of that module is to collect the displays and a standard switch within one enclosure. The displays have PTCs and i use them for measuring air and water temperature. A modified shut off valve (4mm tubes) is used to hold the PTC sensor for water temperature.
To let the device be more energy friendly i install a switch that i can use it on demand within operation of the printers water cooling system. All parts are simply glued and the back cover is fixed with M2x10mm.

The thing is powered via a standard 3pin connector from my "e-capsule".
