I was using this for telework to switch between an external monitor for my personal and work PCs. As stated on the manufacturer's official website, it seems to be usable with Nintendo Switch, etc. Although it is a used item and has some scratches, there are no problems with its operation. It's easy to use; just connect the HDMI cables and press the button on the top. I forgot to take a picture, but the included 0.3m HDMI cable is also included. Also, this product does not require an AC power supply, so it was not originally included. ＜Set Contents＞ ・Switcher unit ・HDMI cable
