In what situations might you use a toggle button vs a switch control vs a checkbox?

Use a toggle switch for binary settings when changes become effective immediately after the user changes them. Use a checkbox when the user has to perform extra steps for changes to be effective. For example, if the user must click a "submit" or "next" button to apply changes, use a check box.

How do you label toggle switches?

The toggle labels should describe what the control will do when the switch is on; they should not be neutral or ambiguous. When in doubt, say the label aloud and append “on/off” to the end. If it doesn't make sense, then rewrite the label.

What can I use instead of a toggle switch?

Toggle switches have their uses, but only if you use them right. As an alternative, you could use radio buttons or check boxes, for example. In both cases, tooltips could help users choose.
