default D value
checkbox
Checkboxes allow the user to select multiple options from a set.
If you have a single option, avoid using a checkbox and use an on/off switch instead.
radio button
Radio buttons allow the user to select one option from a set.
Use radio buttons for exclusive selection if you think that the user needs to see all available options side-by-side.
switch button
On/off switches toggle the state of a single settings option.
The option that the switch controls, as well as the state it’s in, should be made clear from the corresponding inline label.
Switches take on the same visual properties of the radio button.
