The idea here is use an SVG icon in a button and swap that icon out for another when the button is clicked. A button click often suggests an action has been taken, so switching icons can be a nice UI touch to show the change in context and confirm that the action has happened.
A possible use case could be a download button. The icon in the button might initially indicate that the button will trigger a download but change to a checkmark when the button has been clicked.
