An alternative emergency stop switch for the FABtotum Personal Fabricator.

1. connector compatible with Totumduino's door switch (0 €, recovered from a broken external HDD USB case)
2. RCA male plug and 2 meters 2 pole cable (0 €, recovered with from an old surround speaker)
3. RCA female plug (0 €, recovered from a broken car stereo)
4. Emergency stop button mushroom (around 6€, search “AC 660V 10A Red Sign Weatherproof Emergency stop button actuator Switch New” on our favorite online store)
5. Cable tie (0 €, recovered from a broken PC ATX power supply)
6. Two small pieces of heat shrink tubing

The default firmware in Totumduino (FABtotum's proprietary Arduino + Ramps) is built for working with the original front door switch, that is normally open (a very strange choice for a safety device), i must edit the code and recompile the FABlin (the Marlin derivative firmware for the Totumduino).
