  <button onclick="vibro()">TEST</button>

  <script>
  function vibro() {

    if( document.getElementById("vibro_on") ) {

    let doVibro = false;

document.getElementById("vibro_on").addEventListener('click', () => {
  doVibro = true;
});

document.getElementById("vibro_off").addEventListener('click', () => {
  doVibro = false;
});

document.getElementById("do-vibro").addEventListener('click', () => {
  doVibro ? navigator.vibrate([50]) : navigator.vibrate([0]);
});
    <button id="vibro_on">ON</button>
<button id="vibro_off">OFF</button>

<button onclick="vibro()" id="do-vibro">TEST</button>
