Import


import {InputSwitchModule} from 'primeng/inputswitch';

Getting Started

Two-way binding to a boolean property is defined using the standard ngModel directive.


<p-inputSwitch [(ngModel)]="checked"></p-inputSwitch>


export class ModelComponent {
    checked: boolean;
}

As model is two-way binding enabled, setting the bound value as true displays the state as checked by default.


export class ModelComponent {
   checked: boolean = true;
}

InputSwitch can be used in a model driven form as well.


<p-inputSwitch formControlName="enabled"></p-inputSwitch>
