Dareu Optical Brown

You know, I have no use for optical switches on a practical level, none of my boards use them, but boy do they come up with some unique stuff sometimes. I love the look of these weird little Dareu opticals, they are pretty smooth, and they have a little foam gasket so you don't lose the laser light. The browns feel like they have a slightly longer bump than a traditional brown switch, or it might be how light they are making it easy for the bump to carry me further. 

There are no useful specs on these but I measured the travel around 3.7mm
