KHS series Pressure Switch

EXCEL PRESSURE SWITCH

Description

The KHS series pressure switches, including models KHS-503, KHS-506, KHS-110, KHS-516, and KHS-520, are widely used in water, air, and oil pressure systems. They offer high stability and reliability.

Each pressure switch is built with an SPDT micro switch that automatically starts or stops equipment operation based on system pressure changes. Featuring dual control functionality, the switch will automatically start or stop the water pump when the pressure falls below (or rises above) the preset value. Additionally, it can trigger an alarm signal to alert operators for timely intervention, ensuring safe and stable system performance.

• For use with fluorinated refrigerants as well as with air and fluid.
     (Allowable fluid temp. : -10 to 120°C)
• Type HS for Universal application.
• Micro-switch ensures reliable switching.
• With SPDT contact mechanism.
• Installation brackets and 1/4", 3/8" adapters are available.
