What is it

The Multiplexer block (Mux) in the Axe-Fx III is a routing and switching (crossfading) tool. It allows on-the-fly switching between rows on the grid (as long as you have them connected), Inputs 1-4 (Input blocks on the grid aren't required) and USB. Or you can use its Bypass to switch between just two things.

Note that only one input can be active at a time. For multiple inputs, use the Mixer block.

No gap is heard when switching sources.

"If you want cross-fades between amps you would use two amps and the new Multiplexer block which cross-fades between input sources. You can set the input source to be any row or physical input." source

Wikipedia: Multiplexer.

How to switch between sources

Simply bypassing and engaging the MUX disables and enables its set routing.

More control is possible by making use of its Channels, with or without switching scenes.

Also, a modifier can be attached to the Input Select switch, which lets you use a switch or pedal to select the input source.

Example of using the MUX to switch a pedal between operating as a Wah and as a Whammy.
