These things are MX clones but they have no identification whatsoever. The two I'm looking at are an MX Blue clone with a teal slider and an MX White clone with a translucent slider. They appear to be different companies. The teal has no marking on top and on the bottom has the diode symbol with a "V" in front of it. The clear one has a 22 on the back. I'm working on a switch tester, so it would be nice to know what is actually being tested. :)) Thanks for the help guys.
