'How to add the text "ON" and "OFF" to toggle button

On my project I wanted to add a text on my existing toggle code.So I wanted like this, When toggles ON it should display the text "ON" and display the "OFF" text if toggles off. I can't change it to other toggle because it's already have a backend using it. I just wanted only to input "ON" and "OFF" text. Thank you.

Here is my code

  .switch input {
  display: none;
}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ca2222;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked+.slider {
  background-color: #2ab934;
}

input:focus+.slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked+.slider:before {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(26px);
}


/* Rounded sliders */

.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;
<label class="switch"><input type="checkbox" id="togBtn"><div class="slider round"></span></div></label>

You could do it like this:

.switch {
  position: relative;
  display: inline-block;
  width: 90px;
  height: 34px;
}

.switch input {display:none;}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ca2222;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked + .slider {
  background-color: #2ab934;
}

input:focus + .slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked + .slider:before {
  -webkit-transform: translateX(55px);
  -ms-transform: translateX(55px);
  transform: translateX(55px);
}

/*------ ADDED CSS ---------*/
.on
{
  display: none;
}

.on, .off
{
  color: white;
  position: absolute;
  transform: translate(-50%,-50%);
  top: 50%;
  left: 50%;
  font-size: 10px;
  font-family: Verdana, sans-serif;
}

input:checked+ .slider .on
{display: block;}

input:checked + .slider .off
{display: none;}

/*--------- END --------*/

/* Rounded sliders */
.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;}
<label class="switch">
 <input type="checkbox" id="togBtn">
 <div class="slider round">
  <!--ADDED HTML -->
  <span class="on">ON</span>
  <span class="off">OFF</span>
  <!--END-->
 </div>
</label>

Or pure CSS:

.switch {
  position: relative;
  display: inline-block;
  width: 90px;
  height: 34px;
}

.switch input {display:none;}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ca2222;
  -webkit-transition: .4s;
  transition: .4s;
   border-radius: 34px;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
  border-radius: 50%;
}

input:checked + .slider {
  background-color: #2ab934;
}

input:focus + .slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked + .slider:before {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(55px);
}

/*------ ADDED CSS ---------*/
.slider:after
{
 content:'OFF';
 color: white;
 display: block;
 position: absolute;
 transform: translate(-50%,-50%);
 top: 50%;
 left: 50%;
 font-size: 10px;
 font-family: Verdana, sans-serif;
}

input:checked + .slider:after
{  
  content:'ON';
}

/*--------- END --------*/
<label class="switch">
<input type="checkbox" id="togBtn">

If You want to add long text like activate or Deactivate

just make few changes 

.switch
{
        width:90px
}
.slider:after
{
     left: 60%; //as you want in percenatge
}
input:checked + .slider:after
{
       left:40%; //exactly opposite of .slider:after 
}

and last

input:checked + .slider:before
{
    transform: translateX(60px); //as per your choice but 60px is perfect
}

content as per your choice where you have witten "On" and "Off"

Square version of the toggle can be added by modifying the border radius

.switch {
  position: relative;
  display: inline-block;
  width: 90px;
  height: 36px;
}

.switch input {display:none;}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ca2222;
  -webkit-transition: .4s;
  transition: .4s;
  border-radius: 6px;
}

.slider:before {
  position: absolute;
  content: "";
  height: 34px;
  width: 32px;
  top: 1px;
  left: 1px;
  right: 1px;
  bottom: 1px;
  background-color: white;
  transition: 0.4s;
  border-radius: 6px;
}

input:checked + .slider {
  background-color: #2ab934;
}

input:focus + .slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked + .slider:before {
  -webkit-transform: translateX(26px);
  -ms-transform: translateX(26px);
  transform: translateX(55px);
}

.slider:after {
  content:'OFF';
  color: white;
  display: block;
  position: absolute;
  transform: translate(-50%,-50%);
  top: 50%;
  left: 50%;
  font-size: 10px;
  font-family: Verdana, sans-serif;
}
input:checked + .slider:after {
  content:'ON';

Pure CSS with a minimalist approach

All you need is a checkbox with a background as the slider and your content, ON/OFF. The result is keyboard and screen reader accessible.

input {
  -webkit-appearance: none;
  appearance: none;
  width: 64px;
  padding-left: 33px;
  margin: 0;
  border-radius: 16px;
  background: radial-gradient(circle 12px, white 100%, transparent calc(100% + 1px)) #ccc -16px;
  transition: 0.3s ease-in-out;
}

input::before {
  content: "OFF";
  font: bold 12px/32px Verdana;
  color: white;
  text-shadow: 0 1px black;
}

:checked {
  padding-left: 8px;
  background-color: dodgerBlue;
  background-position: 16px;
}

:checked::before {
  content: "ON";
}
<input type="checkbox">

Here I made a toggle button with CSS:

.switch {
  position: relative;
  display: inline-block;
  width: 100%;
  height: 34px;
}

.switch input {display:none;}

.slider {
  position: absolute;
  cursor: pointer;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  background-color: #ca2222;
  -webkit-transition: .4s;
  transition: .4s;
}

.slider:before {
  position: absolute;
  content: "";
  height: 26px;
  width: 26px;
  left: 4px;
  bottom: 4px;
  background-color: white;
  -webkit-transition: .4s;
  transition: .4s;
}

input:checked + .slider {
  background-color: #2ab934;
}

input:focus + .slider {
  box-shadow: 0 0 1px #2196F3;
}

input:checked + .slider:before {
  -webkit-transform: translateX(165px);
  -ms-transform: translateX(165px);
  transform: translateX(200px);
}

/*------ ADDED CSS ---------*/
.on
{
  display: none;
}

.on, .off
{
  color: white;
  position: absolute;
  transform: translate(-50%,-50%);
  top: 50%;
  left: 50%;
  font-size: 10px;
  font-family: Verdana, sans-serif;
}

input:checked+ .slider .on
{display: block;}

input:checked + .slider .off
{display: none;}

/*--------- END --------*/

/* Rounded sliders */
.slider.round {
  border-radius: 34px;
}

.slider.round:before {
  border-radius: 50%;}

Here is the HTML code of toggle button with text:

<input type="checkbox" id="togBtn">
<div class="slider round">
    <!--ADDED HTML -->
    <span class="on">BOOKED</span>
    <span class="off">AVAILABLE</span>
    <!--END-->
</div>
