for SW1: don't use the MTA header
Build:
just install all parts from the BOM. use Glimmer(isolation) in case you attach both regulators to the same metal/cooler
for the switch SW1 - don't use a header - connect directly cables to SW1.
use the trimmer to get the correct voltage
...
for the secondary fuse use a value which is 10-20% bigger than what your device ask (for example a TTSH works great with 2x 500mA fuses and should be work with a 320mA too (depends on the additional mods)
