Graco Toggle Switch 15C979 114277. The earlier version uses the 114277. You will also see a difference in the way they look. Good communication will fix most problems. No exceptions.
New style switch that doesn't pop out when the machine get knocked about in the back of the van, good quality, took a long time to come was 5/6 days late and shipping was expensive, so go to sprayd****t if you don't have a spare machine to keep you going until this switch arrives, 5/6 days not spraying could be very costly
