Hi, this video shows a PlayStation 4 (DualShock 4 Version 2) controller working on the Nintendo Switch. Everything works apart from the NFC reader for Amiibo accessories and it has to be used as a wired controller. The latest update on the Brook Super Converter has allowed motion control and the full range of movement on the left and right analogue sticks.
This is not supported by Nintendo and it could be patched on a later update so it may not work in the future (this video was made August 2017).
Many thanks Vince
