Can I use getCriteria to only return entries with a specified lightswitch field set to on?

Question

I'm building a plugin that will check all existing entries in a section when a single entry is flagged as featured and turn off any existing featured entries. I'm using a lightswitch field to turn on and off entries. Is there a way to use the craft()->elements->getCriteria(ElementType::Entry); to return just the entries with the lightswitch field turned on?

Cheers

This should do it:

$criteria = craft()->elements->getCriteria(ElementType::Entry);
$criteria->section = 'mySection';
$criteria->myLightswitchField = 1;
$entries = $criteria->find();
