### Events

| Name | Description |
| -- | -- |
| ``change`` | Triggered when user toggles the state of the switch. The callback parameter list is `(checked: boolean)`. `checked` denotes whether the switch is on. |
| ``input`` | [^event-input] |

^^^event-input
:::badges
`v-model`
:::

Triggered when the check state is changed. The callback parameter list is `(val: *)`, with `val` being the current value of `v-model`. Unlike the [`change`](#events-change) event, `input` is triggered even without user interaction.
^^^

Additionally, `Switch` exposes the following native events:

`auxclick`, `click`, `contextmenu`, `dblclick`, `mousedown`, `mouseenter`, `mouseleave`, `mousemove`, `mouseover`, `mouseout`, `mouseup`, `select`, `wheel`, `keydown`, `keypress`, `keyup`, `focus`, `blur`, `focusin`, `focusout`.

The callback parameter is the corresponding native event object for all events above.
