<mndw-switch>

The host has role="switch"; the toggle takes effect immediately and emits mndwchange.

Examples

Off and on

<mndw-field label="Automatic updates"><mndw-switch name="updates"></mndw-switch></mndw-field>
<mndw-field label="Dark theme"><mndw-switch name="theme" value="dark" checked></mndw-switch></mndw-field>

Disabled

<mndw-field label="Managed setting"><mndw-switch checked disabled></mndw-switch></mndw-field>

Reference

checked and value reflect. value defaults to on and is the token submitted while the switch is on. The shared form properties are name, disabled, required, and invalid. Parts are track, thumb, and label.

mndwchange carries {checked: boolean} and fires on user activation, not on a programmatic write. Space and Enter toggle the host. The host carries role="switch", the tab stop, and keyboard handling; the shadow track and thumb are presentational. FormData includes value while checked and omits the switch while unchecked; form reset restores the authored checked attribute.

required is accepted but inert because a switch always holds a value. invalid is reflected for styling; it sets no validity flag or aria-required, and <mndw-field> owns the aria-invalid announcement. The accessible name comes from an external label or field. Slotted content is rendered in the label part, but a wrapping field still renders its own label.
