Panel Mounted Pneumatic / Electric Switch (No Factory Calibration)

Pneumatic-electric switches (P658A,B,E and F) used to convert a pneumatic signal from a controller to an electrical switching action (SPDT) to provide start and stop control of equipment such as fans and pumps. Replacement devices available for Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell pneumatic/ electric switches. FeaturesModels 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.
