Ui-Template Node for Custom Images

Heya,

can somebody tell me a realy simple example on how to create a switch with the ui_template node with any custom icon from the internet?

I have this one here f.e.
<span class="iconify" data-icon="emojione:couch-and-lamp" data-inline="false"></span>

I found many icons on this page: Icon Sets • Iconify

maybe as per - node-red-dashboard (node) - Node-RED
