Suburban furnace troubleshooting help

I checked my sail switch and tell me what you think. I started the blower and it ran fine, still no spark. In an effort to test the sail switch i touched my multimeter red to red black to black. The meter "jumped" and then showed nothing. Then my furnace sparked and started up. I did this 3 times in a row. This tells me that sail switch is bad. Am I correct?
