public class AutochangerTwoLatches
extends MobileItemModule

This class represents a model for the 2 Latches of the autochanger. The Latches hold a filter on the trucks. There is one latch on each side of the filter. Because the ACTION open (or close) for 2 latches is different from opening (or closing) one Latch, then the other one, it's more convenient to have a class to represent 2 Latches at a time.
