This should be easy ….
I’m looking for a locking toggle, ON-OFF, SPST, Screw terminals. Honeywell at $75 ea. Is that my only choice?

I’ve been using these locking toggle switches on the last couple of projects. They come in DPST, DPDT, ON-ON, ON-OFF-ON and such. The ON-OFF-ON is what I use to select “Normal” and “Alternate” power sources for each avionics buss.
These are solder type (my preference by far over screw terminals), good contacts, rugged and reasonably priced.

Which toggle switches?
Is it OK to use solder type lugs in an aircraft? I was under the impression that the wires would break at the solder joint due to vibration. SNIP
Switches with riveted tabs are trouble prone from my experience, and using a solder connection is way more trouble than a simple crimp terminal with screw connection.
Electrical systems seem to be where most folks think using low quality parts won’t have any consequences, but those choices most definitely effect electrical system reliability.
Don’t believe me, just check the almost daily postings of electrical systems problems on VAF.
Walt, why do you consider the switches that Carl linked (NKK S1AL) to be low quality parts? I believe they use a solid and not hollow rivet through the lugs. All non-screw toggles that I've ever seen use rivets to attach lugs (faston or solder), it's a common manufacturing practice.
Thanks

All my toggle switches are "Carling" and were purchased either from DigiKey or Mouser. They have soldered, quick-connect, and screw terminals. The ones with screw-in terminals were sometimes hard to find, but I didn't want the other kinds, so I had to look around. Here are some model numbers I found for various types of switches. Do due diligence and confirm them:
SPST On-Off 2FA54-73
SPDT On-Off-Mom 6FC58-73
DPST On-Off 2GK54-73
DPDT On-On-Off 2GG54-73
DPDT Off-On-Mom 6GM5E-73
DPDT On-On-Off 2GG54-73
Unrelated story. I went to high school with Carling's son. Fun times. We used to go to the factory weekend nights and load the truck with bad pallets then burn huge bon fires on Boca Chica beach where they launch rockets now. Nothing out there but sand and water back then.
