P61 Series
Pressure Switch
Description
The P61 Series Pressure Switches automatically control
residential water pumps, small air compressors (not requiring mechanical release
valves), and other electrically-operated pressure equipment. They use a
Double-Pole/Single-Throw (SPDT) switch that opens on pressure rise.
The P61 switches are enclosed in a compact NEMA 1 case
and are available with choice of four standard ranges.
Features
- small size, narrow design, and small turning radius
allow control to fit in tightly-spaced applications
- nylon-reinforced Buna-N diaphragm provides long life
and trouble-free operation
- large screw-type terminals allow quick and easy wiring
