Highlights on Pressure Switches


Lefoo has a wide range of pressure switches for the industry in general. Our models were developed based on many years of research in partnership with industries around the world, seeking to meet specific needs with superior precision and durability. Among these models, we highlight some of them:

LF17-W Water pressure switch (15-250PSI): The robust LF17 pressure switch was designed to meet the most demanding demands in the heavy commercial water pump system. This pressure switch allows direct connection to motors with up to 3 phases and 5 HP, with normally closed contacts.

Its simple design makes it easy to use for professionals and non-professionals. It has a plastic composite cover, resistant to corrosion. No looping in your wiring. Its installation is simplified through direct cable, with ample space for connecting the wires. It has grounding screws and extreme ease of adjustment.


It has a stainless steel connection as an optional item, in addition to other optional connection accessories.


LF20-H pressure switches are robust, compact and designed to operate in harsh environments under various pressure situations. Due to its special internal design, this switch can tolerate high pressure spikes inherent in many pressure systems.


The switch is factory calibrated, but also allows adjustments in the field. Kapton's diaphragm makes it compatible with many gases and liquids. Various other diaphragm materials and electrical terminations are available.


This recently restructured version of our LF20 uses a 3-piece construction and screw-machined components that is capable of handling much higher pressures than previous models.
