Manufacturer Hi-Tek
Notes At the moment, I am not concerning myself with the shape or size of eyes: unlike the discrete concepts found with Alps switches (a switchplate is either “short” or “long”), eye shape and size appears to be rather harder to gauge, but could potentially be addressed once we have found a meaningful way to understand and categorise them.

deskthority.net The pale grey switch under the space bar is marked with a dab of yellow paint to indicate a heavier switch, which seems curious considering that the slider is already a different colour.
