If you followed my instructions, your script should now similar to this:

from lucid.rules import rule, addRule # Needed for defining and adding a rule
from lucid.triggers import ItemStateChangeTrigger, CronTrigger # Import the different type of triggers that you will be using

@rule
class StepByStep(object): # Giving the class a unique name
    def getEventTriggers(self):
        return [
            ItemStateChangeTrigger('My_TestSwitch_1'), # Triggering when the switch changes its state.
            ItemStateChangeTrigger('My_TestSwitch_2', ON), # Only trigger when switch turns on
            CronTrigger('0 0/2 * 1/1 * ? *'), # Runs every other minute
        ]

    def execute(self, modules, inputs):
        self.log.setLevel(DEBUG)

        if self.event.isItem:
            self.log.debug('One of the test switches has changed its state')
            self.log.debug('Triggering item name: \'' + unicode(self.event.itemName) + '\', state: ' + str(self.event.state))

            if self.event.itemName == 'My_TestSwitch_1':
                events.postUpdate("Test_String_1", "CAT")

        elif self.event.isCron:
            self.log.debug('A cron event occurred')
            events.postUpdate("Test_String_1", "DOG")

addRule(StepByStep()) # Needed to add the rule, use the same name as defined for the class
