Looks like this is on a Shotgun so 100% a magazine cutoff,
when its flipped to the right with no red dot visible rounds should feed from the magazine normally, When flipped to the left so the red dot is visible it should stop the next round from feeding into the Chamber.
I have something just like this on my Browning Auto 5,
