Solution

JavaScript makes it easy, so just add this JavaScript tag to end of <body> :

  <body>
    <div class="switch">
      <input
        id="language-toggle"
        class="check-toggle check-toggle-round-flat"
        type="checkbox" />
      <label for="language-toggle"></label>
      <span class="on">BN</span>
      <span class="off">EN</span>
    </div>

    <script>

      document.getElementById("language-toggle").addEventListener("click", myFunction);

      function myFunction() {
        if (document.getElementById("language-toggle").checked) {
          window.open("https://www.google.com/", "_blank");
        } else {
          window.open("https://www.facebook.com/", "_blank");
        }
      }

    </script>

  </body>

If you want to open links in same tab change "_blank" to "_self"
