If you know the make and possibly serial number of your furnace you can identify the part number that way.
If you never had the furnace cleaned you may find the switch is just dirty or covered with dust and can't make contact. Its just a simple micro switch with a tail on it that gets closed when the blower starts giving the green light to the gas valve to open and then ignite. You may be able to just clean the one that's in there. They are an inexpensive part - I carry a spare in my parts bin just in case.
