InputSwitch is used to select a boolean value.

import { InputSwitchModule } from 'primeng/inputswitch';

Two-way value binding is defined using ngModel.

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

InputSwitch can also be used with reactive forms. In this case, the formControlName property is used to bind the component to a form control.

<p-inputSwitch formControlName="checked" />

Enabling ngModel property displays the component as active initially.

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

Invalid state style is added using the ng-invalid and ng-dirty class to indicate a failed validation.

<p-inputSwitch [(ngModel)]="checked" class="ng-dirty ng-invalid" />

When disabled is present, the element cannot be edited and focused.

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

p-inputswitchContainer element.
p-inputswitch-checkedContainer element in active state.
p-inputswitch-sliderSlider element behind the handle.

Screen Reader

<label for="switch1">Remember Me</label>
<p-inputSwitch inputId="switch1" />

<span id="switch2">Remember Me</span>
<p-inputSwitch ariaLabelledBy="switch2" />

<p-inputSwitch ariaLabel="Remember Me" />
