* [ Note: ] [The use of metallic diaphragms where higher pressures, shock or heavy cycling is expected should be avoided. When choosing a ]
pressure range, it is recommended that the switch operate in the middle 80% of its adjustable range. Switching may not be accurate in the lower
and upper 10% of the range.
Switches come complete with operator’s manual.
Ordering Example: PSW-115, Buna-N diaphragm, [1] ⁄4 brass FNPT thread, range of 50 to 500 psi and adjustable deadband.
