Switch
Switch is a Compositing effect.
What it does
Section titled “What it does”Switch shows the picture on the socket its Index names, counting from in0. It is a box in a node graph composition and is not offered on a layer’s stack. There is always one spare socket beyond the last one wired. An unwired socket, or an index past the last socket, shows nothing. A bypassed Switch shows its first socket.
Only the picked socket’s picture is decoded and drawn, unless something else reads the others. With a wire or an expression on Index, every socket is decoded and only the picked one drawn.
Parameters

What each control does
