The CCS 6900P38 is a pressure switch designed by Winco Fluid Power Inc. 

• Design Features:

  • The 6900P38 pressure switch replaces the elastic creep deflection of conventional pressure switch sensors with the negative spring rate of a disc spring combination. This innovative design has been proven to be highly reliable, especially in applications like jet aircraft, where it has been the only acceptable design for many decades.
  • Unlike traditional diaphragm-based sensing elements, the 6900P38 uses a disc spring to respond instantaneously when system pressure reaches the set points.
  • Set points remain stable and are not sensitive to shock, vibration, temperature variations, or other ambient conditions.
  • The switch is binary – it’s either “on” or “off,” eliminating the tracing of fluctuating pressures.
  • Adverse effects of pump ripple, contact chatter, fatigue, premature wear, and other common switch problems are significantly reduced.
  • Maximum life expectancy with lifelong reliability and precise repeatability assured.
  • A wide range of set points is available in each switch model series.
