What looks like it fits Nintendo Switch but does not
Screen protectors and cases sold for the OLED model are cut for a larger panel and will not sit correctly on this console.
These sit in the same memory cards aisle and are confirmed for a different exact model. We have no published answer saying any of them fits Nintendo Switch, so treat them as unverified for this device rather than as a fit.

Coming from an older model
Why a previous-generation memory card may fail here
The original Switch uses a 6.2-inch LCD, rail-mounted Joy-Con that slide on from the side, and a standard microSDXC card slot.
Accessories bought for this console mostly carry across to the OLED model apart from screen protectors. They do not carry across to Switch 2, which is a larger console with a different controller attachment and a different card standard.
