HELP!! Upfitter switch wire capacity- Fire Danger??

[HPNQ420]

I am generally skeptical of screws to pinch wires to secure them for a reliable electrical connection. These can and likely will loosen in a vibration and thermally cycling environment. The raw leads on the "bad" or perhaps merely inconvenient design Ard superior with a proper crimp and crimp tool.

The unwanted potential side effects of a loose screw terminal connection include: poor device performance, high resistance, overheating, corrosion and fire.

Crimp a high quality ring terminal to the wire before attaching it to a screw terminal and all is well (as long as the screw terminal is of good design and quality). SOP for MS switches in aircraft.

Can confirm-set screws are not “set and forget” and will indeed loosen. Then catch your shit on fire.

Yes, for stud terminals that support ring terminals.

Those mentioned above (post #27), which I am referring to, absolutely do not support ring terminals. These are the ones...

Not that I look in detail, those are horrible!

Edit: No strain relief either.

Turns out they make exactly what I had in mind! 6 relay controlled circuits. Mount this near the upfitter wires in the engine compartment, splice the leads and job done!

Anyone find a good place to mount this?
