SNAP-ACTION SWITCH SWITCH HOUSING Nason Switch Designs Ensure High Reliability BASE CROWN All of Nason’s pressure switches use a snap-action electrical device activated by an elastomer diaphragm or piston, offering a precise and repeatable design. The snapaction design will maintain its state with contacts either open or closed, until a precise set point is reached when it will snap over center to a new state. It will remain in that state until a distinct change towards its original setting is sensed, at which time it will snap back to its original state. The design’s snapaction feature prevents...
