Configuration Frontend

Hi everyone.

I’m trying to do a very simple thing I think, but I’m not knowing how to. Maybe someone can help me.

Now I’ve this card:
image

entities:
  - entity: switch.vacuum
type: entities

And I want to change the icons to look like this:
image

I only want to change the switch default button icons for this card. Does anyone know how to do this?

Thanks a lot!
