No effect on setting height and width for Ti.UI.Switch control

I created a new alloy project (1.5.1) and added a switch control. Why does the height and width have no effect on the switch no matter what size i give?. It just sticks to a definite size. Trying to do this on the iOS.

index.xml

<Alloy>
    <Window class="container">
        <Label id="label" onClick="doClick">Hello, World</Label>
        <Switch value="false" top='100' height="100" width="200"></Switch>
    </Window>
</Alloy>
