Overview
Pneumatic-electric switches convert a controller's pneumatic signal to electrical switching, providing start and stop control. Replacements available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell pneumatic/ electric switches.
Features
Models available for surface or panel mounting.Barb protected by open cage.All ferrous parts plated to prevent corrosion.Factory calibrated setpoint field adjustable to meet job requirements.Neoprene diaphragm element.
