If you're only using 2 sources, this will work perfectly and for about $8. If you're using 3 or more, it's more budget friendly to use a remote based system. But automatic switchers can be found for $250 and up. The issue with automatic toslink switchers is the fact that optical doesn't carry current like other cables. That makes the switcher much more expensive because it needs optical sensors and circuitry rather than a simple current detector like automatic HDMI switches.
