Place Custom Checkbox Icon to right of label Bootstrap 4

The custom checkbox is created with pseudo elements so their positioning needs to be adjusted relative to the label.

.custom-control.custom-checkbox{padding-left: 0;}

label.custom-control-label {
  position: relative;
  padding-right: 1.5rem;
}

label.custom-control-label::before, label.custom-control-label::after{
  right: 0;
  left: auto;
}

<div class="custom-control custom-checkbox mb-3">
  <input type="checkbox" class="custom-control-input" id="customCheck" name="example1">
  <label class="custom-control-label" for="customCheck">Label</label>
</div>

The earlier @serg-chernata answer doesn't seem to work for me with custom-switch. Here's an example i got working.

CSS

div.custom-control-right {
    padding-right: 24px;
    padding-left: 0;
    margin-left: 0;
    margin-right: 0;
}
div.custom-control-right .custom-control-label::after{
    right: -1.5rem;
    left: auto;
}
div.custom-control-right .custom-control-label::before {
    right: -2.35rem;
    left: auto;
}

HTML

<div class="custom-control custom-control-right custom-switch">
    <input type="checkbox" class="custom-control-input" disabled id="customSwitch2">
    <label class="custom-control-label" for="customSwitch2">Right switch element</label>
</div>

Edit: changed left:initial to left:auto to make it work with IE11.
