2. Product Specifications:

LF56 series pressure switches are mainly used to control the pressure of boiler or water tower regulating the system. When the system pressure exceeds the set point, the switch will cut off the circuit for protection.

With SPDT contact arrangement, LF56 switch can detect the pressure change and shift the internal status accordingly to control the on/off of external circuits, which is available for the pressure control, limit, and alarm of non-hazardous liquid, gas, and steam.
