I see now there's some confusion. When it said "toggle button", I thought a Switch was being discussed, but when I clicked on the OP I see it actually does mean button, so we've got some people talking about switches and some people talking about buttons (and yeah, a switch should show current state, but a button should show what would happen if you clicked it).

Buttons/switches trigger an immediate action, whereas checkboxes usually do not (such as on a settings page, where no changes are applied unless you click "save").
