My pictures say it all, so I'll keep the text short. I'm looking for high quality miniature DPDT slide switches, with a standard 19mm screw spacing. I can't find a source for them in the United States. I've purchased or investigated every offering from Digikey, Mouser, eBay, Fry's, Radio Shack, and Amazon, and it's all garbage. I mean that in the literal sense; most of them I threw straight into the trash. There is no way I would EVER put such junk into my products.
So where can I find a high quality switch? I'm not looking for volume (at least not now), but I also need more than just a few samples. The only source of Taiwanese switches I know of is vintage Futaba RC switches, but they cost up to $10/each, and they're literally just $1 slide switches stuffed into a two-cent plastic housing:

I can't keep buying and gutting those $10 Futaba switches. My research has pointed me toward "Taiwan Alpha" and "Taiwan MEC" as high quality sources, but I can't find an American distributor. It's almost unbelievable that Taiwan doesn't export to the U.S. anymore. Most of the stuff that's made in America is also garbage btw; Taiwan is the highest quality producer I know of. They skimp on labor, not quality.
Here is the criteria for high quality:1. Large fillets of red epoxy around the base of the pins
2. High quality base material
3. Wide steel legs that FIRMLY hold the base material against the metal housing (the Toy and Comax have very thin, narrow, and weak legs compared to the Taiwanese switches).
4. High actuation force (300 - 500 gf).
5. Contact resistance of 15 mOhm (the cheap ones are 30 mOhm)
6. Ball detent (as opposed to a spring return)
7. High cycle count (10,000+)
8. Metal frame thickness of at least 0.52mm (0.020"). The "Toy" frame is only 0.39mm (0.015"), whereas the "M" frame is a massive 0.62mm (0.024"). It's not a coincidence that the "M" switch has both the thickest frame and the best tactile feel.
9. At least two points of electrical contact per pin.
Here's an example of dimensions:
