checkboxes - Toggle button vs. check box and toggle switch

XAML for Windows 8 offers 3 controls for toggling: toggle button, check box and toggle switch.

The Windows 8 UX guidelines explain and compare the check box and the toggle switch, but make no mention of the toggle button.

How and when do I use it? Should I use it at all, considering the – in my opinion – lower affordance and discoverability? What are its pros and cons?

Answer

A toggle button usually makes the most sense when you have a number of buttons to choose between. Something like a set of radio buttons in interaction.

Otherwise, one toggle button on its own isn't clear in terms of either interaction or affordance, and the other options are better choices.
