+  Renders a switch as a button.
+
+  If you want to render a switch as part of a form, use the `input/1` component
+  with the type `"switch"` instead.
+
+  Note that this component only renders a button with a label, a state, and
+  `<span>` with the class `switch-control`. You will need to style the switch
+  control span with CSS in order to give it the appearance of a switch.
+
+  ## Examples
+
+      <.switch
+        label="Subscribe"
+        checked={true}
+        phx-click="toggle-subscription"
