PRODUCT DESCRIPTION

 

CSPS series pressure switch is an automatic control switch that receives pressure signals and converts them into electrical signals to achieve on or off. When the system pressure is higher than the action setting, the built-in metal diaphragm flips instantly, driving the electrical contacts to connect and disconnect. When the system pressure drops to the reset setting, the metal diaphragm will automatically flip over again and return to its initial state.

The switch automatically controls the pressure to ensure that the system is always in a safe working range.

The advantages are compact structure, sensitive movement, precise stability, and long cycle life. It is widely used in many industries.
