Co-Gain Magnetic Linear

You know, I'm not even mad these don't have real names, the serial numbers are fine. So we finally found the manufacturer of these weird opticals, Co-Gain/Xuda, and even found a website and taobao storefront. So of course I had to buy all their OEM level stuff. These ones are actually a magnetic switch largely reusing the optical molds which is neat. They don't even get a serial number though which is sad.
