<paper-checkbox>
paper-checkbox is a button that can be either checked or unchecked. User can tap the checkbox to check or uncheck it. Usually you use checkboxes to allow user to select multiple options from a set. If you have a single ON/OFF option, avoid using a single checkbox and use paper-toggle-button instead.
See: Documentation, Demo.
