Pneumatic Switches
P658 Pneumatic/Electric Switch
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.
• 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.
Air Connections: Barb fitting for 1/4 in. (6 mm) O.D. plastic tubing
Frequency: 60 Hz
Operating Humidity Range: 5 to 95% RH, 80 F (27C) max wet bu b
Temperature Range: 40 F to 140 F (4 C to 66 C)
Maximum Safe Operating Pressure: 30 psi (207 kPa)
Pilot Duty Ratings: 750 VA @ 125, 250 or 277 Vac
Switch Operation: Converts pneumatic signal to electrical switching
action (SPDT)
