## When To Use
2016-07-26 09:17:46 +08:00
- If you need to represent the switching between two states or on-off state.
- The difference between `Switch` and `Checkbox` is that `Switch` will trigger a state change directly when you toggle it, while `Checkbox` is generally used for state marking, which should work in conjunction with submit operation.

## FAQ
### Why not work in Form.Item?
Form.Item default bind value to `value` property, but Switch value property is `checked` . You can use `valuePropName` to change bind property.
```tsx | pure
< Form.Item name = "fieldA" valuePropName = "checked" >
< Switch / >
< / Form.Item >
```
