I am building a RV8 and Have a couple of Carling but switches SPST. I am
not impressed with their fast on tabs. I know they will probably work just
fine, but I am thinking of using some Honeywell switches that have screw on
terminals. I also have a space issue that the screw on terminals would
help.
Are these Honeywell switches a good choice?
Mike

Those are terrible and will cause the wings to fall off. To be safe, box
them up and send them to me.
;-)
Seriously, screw terminals are more likely to come loose than the fast
on tabs, because any counter-clockwise pressure on the ring terminal
(tension on the wire) will try to loosen the screw. And proper ring
terminals take the same space as fast on terminals. If you're thinking
of just hooking the wire under the screw head, don't go there. Five
years from now, when you're making changes to the panel wiring, you'll
be cussing yourself as you lie on your back under the panel with your
legs in the air, trying to find the screw you dropped into the bowels of
the a/c.
Now if you want the Honeywells for the looks, or you believe you need
space-certified internal quality, then go for it.

No its a clearance problem. The tabs on the Carling switches I have go
straight out the back. When you add the female connector it adds almost
an Inch. I just need the room and the NT Honeywell switch is just a couple
ob bucks more than the Carling ones. There are also two versions of the
Honeywell , One has silver contacts the NT does not. That could really be
overkill.

Just a contrarian view on Wings falling off, I work for an airline with 52
aircraft and each with 104 c/b's with washers and screws. No wins have
ever even gotten loose nor do the machine screws when correctly installed
and torqued. Space limitations and wire loom routing would never work with
Fast-ons. YMMV.

Search for Flag Faston Connectors.

Gold plated switch contacts are for lighter loads.
Silver plated switch contacts are for heavier loads.

And all the bolts that attach parts that are subject to rotation have
castle nuts and cotter keys, right?
My original post was intended to be a bit light hearted, but it's not a
falsehood. Yes, if everything is done properly, screw terminals will be
secure. But try half installing a blade terminal on its blade, and half
tightening a screw on a ring terminal. Then see which is more prone to
loosening when the wires are wiggled. I know none of us who are perfect
pilots and perfect a/c assemblers would ever make such a mistake, but
'stuff happens'.
The real point is that quality blade connectors are plenty good enough
for aviation use.
