Kailh PG1316S Ultra Thin Butterfly Switch (10 pack)

Kailh PG1316S is a relatively new and esoteric switch, originally designed for laptops. It is an SMD style switch (meaning it has pads rather than the usual pins that get soldered).

As a less known switch, there aren't many keycaps options at the moment, and the DIY community currently relies on 3d printed ones. mikefive of r/emk has designed a keyboard using this switch and has shared . 

The datasheet is available here, Kicad footprint (created by r/emk mikefive).

Comes in packs of 10. A sample keycap (clear, injection molded) is provided with each order.

More 35gf switches are coming soon.
