A quote from the article:
Most of us are familiar to standard mechanical switches found in popular gaming keyboards. Standard Cherry, Kailh, and TTC switches share similar designs using physical metal on metal contacts to register a keystroke. With the Tesoro Excalibur SE Spectrum, this keyboard utilizes optical key switch technology. Each key uses an infrared sensor to detect when the key is registered. This design eliminates metal on metal contacts and boosts the keystroke life cycle from 50 million to an insane 100 million. It also has per key back lighting, a spill and rust resistant design, and internal drill holes in case of spills. In this article for Benchmark Reviews, let's a look at the Tesoro Excalibur SE Spectrum with blue optical switches.
