When I think “toggle” switch, I think in terms of binary states: on or off. Which is why I used a light switch as an example rather than a media play/pause button which can have multiple states. In that scenario, yes, it would be more intuitive for the button to display the action it will perform.
Up doesn’t mean on and down doesn’t mean off when you have multiple switches for the same thing.
