    * 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.
