|MADE IN THE USA|
At Nason, we’re known for the high-quality reliable pressure switches and other components that we build right here in the USA. You can choose from the wide range of high-pressure switches and low-pressure switches that we have in stock or request a custom model to fit your unique specifications. We built our reputation on the accuracy, reliability, and flexibility of our products.

No matter what your application is, you’ll find the component you need at Nason. We offer low-pressure switches with set points that start as low as 2 psi and high-pressure switches with set points as high as 7500 psi.
The precise snap-action design of our switches prevents “creeping” to offer the ultimate in accuracy and reliability.
We build our pressure switches in the USA from high-quality materials and put them through rigorous testing to ensure they perform reliably. Nason switches stand up to demand, working around the world in critical operations under the harshest conditions.
All of our pressure switches are designed to last for up to 1 million operating cycles. This long cycle from installation to maintenance or replacement makes the cost of ownership for premium Nason parts even more affordable.
Nason pressure switches have the accuracy, reliability, and flexibility you need, whether you’re working in high-pressure, structured hydraulic applications or low-pressure, faster moving pneumatic applications.
These reliable components feature more options for electrical connections than our competitors offer. And if you’re looking for an option that you don’t see, let us know and we will be happy to make it for you.
Some high-pressure switches are designed with hardened steel pistons to provide maximum precision without creeping and longer life cycles in the most extreme applications and conditions.
Nason’s low pressure switches use a snap-action electrical device activated by an elastomer diaphragm. This prevents incidental contact near its switch point, which is a common problem in switch designs that “creep”.
Our elastomer diaphragms move a precise .040 of an inch, ensuring accurate, instantaneous contact under all operating conditions. We test 100% of our pressure switches for accuracy, and they are UL, CSA, and military approved.
High-pressure switches sense discharge pressure from the system. When a precise set point is reached, the contacts snap over to a new state and remain there until pressure distinctly lowers, triggering the contacts to snap back to their original state.
Low-pressure switches sense pressure in the system. They remain either open or closed until pressure reaches a precise set point, which triggers them to snap to a new state. They remain in this state until pressure rises again, triggering them to snap back to their original state.
A pressure switch is a device that provides electrical feedback in response to a pre-determined pressure level being reached. An electrical switch opens and closes at a specific pressure, while the sensing element initiates a control action, such as launching an alarm.
This device consists of a sensor and a switch that opens and closes when specific pressures are reached. The sensor converts one form of energy to another. Pressure switches have two operating points: one which starts the pump, caused by falling pressure, and the other which stops the pump, caused by rising pressure.
There are two types of pressure switches: mechanical, also known as electromechanical, and electrical, also known as solid-state. Choosing the right pressure switch mechanism depends on the application in which it will be used.
Electromechanical: An electromechanical pressure switch has traditional-style mechanical switches with moving parts.
Benefits: Electromechanical pressure switches are not voltage-dependent and can switch higher currents.
Solid-state: A solid-state pressure switch doesn’t contain moving parts. This type of switch has more versatile offerings such as programmable functions, LED displays and multiple adjustable output switch configurations (normally open, normally closed or both).
Benefits: Solid-state pressure switches have a longer life span, are more accurate, and are shock and vibration resistant.
Pressure switches are used to operate an electrical circuit when a certain pressure level is exceeded. Pressure transducers produce a continuous signal that indicates the pressure level.
