I am currently working on a case for the Nextion 3.5" Enhanced display that will be connected to an Arduino Nano. In order to update the Arduino Nano I have to disconnect the TX/RX serial pins. I don't want to have to disassemble the whole case for every update of the Arduino so I created this latching switch based on two mechanical micro switches. The circuit will stay open until the switch is switched - disconnecting the Nextion - for the arduino to update. My end use will be to incorporate the design into my Nextion case.

This part was printed on a Creality CR-10 Smart Pro with Eryone PLA+ filament. I was pretty disappointed with the filament as there were bubbles every 30 sec or so.

Microswitch dimensions: 12.5mm x 6.5mm (lever not included)

Switch case dimensions: 32mm wide 18mm deep 19mm tall

Assembly screws are 2mmx8mm flange head Philips drive; removed from servo drive gear.
