HPS41 series pressure switches are mainly used to control pressure of boiler or water tower regulating
system. When the system pressure exceed the setting point, the switch will cut off the circuit for
protection.With SPDT contact arrangement,HPS41 switch can detect the pressure change and shift the
internal status accordingly to control the on/offof external circuits,which is available for the pressure
control,limit and alarm of non-hazardous liquid, gas and steam.
