NEW THINKING
for better solutions
After more than sixty years of producing quality electrical, hydraulic, and pneumatic components for use in military and industrial applications, we’ve established ourselves as industry leaders in efficiency, flexibility, and customer service. Our line of custom engineered switches offers proven reliability and unmatched customization.
Parts made by Nason are used around the globe in the harshest of environments, where engineers and users depend on the precision and reliability we promise to each of our clients. Our switches undergo rigid testing to ensure reliable service. We leave nothing to chance, crafting and assembling all parts within our own plant in the United States.
Our offering of options in ratings, connections, and mounting is unmatched in the industry. Besides our extensive stock of legacy switches, we keep an incredibly diverse supply of optional media and electrical connections to match our clients’ varied design specifications. Whatever your challenge, our technical support is available to you before and after the sale.
Our 50,000-square-foot manufacturing facility, staffed with experienced design engineers and customer service representatives, exists solely to meet your engineering needs, big or small. We offer free switch samples to let you make sure that our customized design fits your particular application, so you can specify Nason with confidence. And we require no minimum orders, so even the smallest design challenge is no problem. Once you’ve looked over our products’ 3D CAD models and have made your design decisions, our extensive component inventory will ensure rapid assembly, often shipping products within days.
Contact Nason to see how our custom engineered switches can fit your exact application.
NASON SWITCH
DESIGNS ENSURE
HIGH RELIABILITY
All of Nason’s pressure switches use a
snap-action electrical device activated by
an elastomer diaphragm or piston, offering
a precise and repeatable design. The snapaction
design will maintain its state with
contacts either open or closed, until a precise
set point is reached when it will snap over
center to a new state. It will remain in that
state until a distinct change towards its original
setting is sensed, at which time it will snap
back to its original state. The design’s snapaction
feature prevents contact intermittency
near its switch point, which is common
in creeper designs. As system pressures
fluctuate, our switches' inherent differential
prevents searching. Nason uses only the
highest quality snap-action switches. These
switches and Nason’s are UL, CSA, and
military approved.
Accuracy
Our elastomer diaphragm or piston, which
moves a precise .040 of an inch, ensures
accurate, instantaneous contact under all
operating conditions. While nitrile is preferred
for general use, we can also provide ethylene
propylene, fluorocarbon, fluorosilicone, and
neoprene, depending on your need. Nason
tests 100% of its switches for accuracy.
Reliability
Under most operating conditions, Nason
switches have an operational life of over
one million cycles. Smart design, quality
components, and careful assembly make a
switch that easily outlasts the competition.
Flexibility
We offer media connections in NPT, BSP,
SAE, JIS, DIN, MS, and many more (refer
to page 23) as well as all the electrical
connections depicted on the facing page.

Description
The NT25 Series digital/configurable is an industry
first. This industrial pressure transducer features
stability and accuracy over a wide temperature
range. It is lower in cost than competitive units
typically not found in older analog designs. It is also
plug and play, which is not found in most lowergrade
competitive units.
With its proprietary digital/ASIC technology, the
NT25 Series features field-proven redundant sensing
elements without the need for solder in resistors or
trim pots that can drift over time. This provides years
of excellent performance and reliability even in the
harshest applications. This combined with optional
4x over pressure and the optional integrated
temperature or pressure digital switch feature,
makes the NT25 Series truly an industry first and
second to none.
For extreme applications where power washers
are used for wash down, the NT25 Series optional
IP69K seal, another industry first, makes it ideal no
matter what the environment.
With its flexible, low-power design and lower
manufacturing costs, the NT25 Series offers
outstanding value and makes it ideal for custom
wireless applications.

Set Point for Either Pressure

range and this will be the set point (40% of a 1000 PSI range will have the set
point at 400 PSI) “P40”. For temperature, simply select in degrees C where you want
the set point to be (selecting 40°C will be represented by "T40" in the part number).

Description
What makes the NESD model stand apart is
the unique LED display - which allows for 360°
scrolling, or you can lock the display in one
location. It also features field-programmable set
points and hysteresis.
The NESD model incorporates redundant
sensing technology, allowing for notification that
the sensor needs to be replaced before it might
fail (maintenance mode), eliminating operational
downtime.
The NESD model pressure switch/transducer
comes standard with one digital output (NPN or
PNP), optional analog output, operates from 10.5
to 28 VDC, and is IP67 certified.

Snap-Action Switches
Nason uses only the highest quality snap-action
electrical switches which insures a positive, instantaneous electrical contact under all operating conditions. Nason electrical switches are UL, CSA, CE, and military listed. Ask about our new environmentally sealed snap-action switch.
Diaphragms
Nason pressure switches incorporate elastomer
diaphragms to provide a positive media seal. Nitrile is
the material of choice for most applications. Ethylene
propylene, fluorocarbon, fluorosilicon, and neoprene
are readily available for specific applications.
Differential
A distinct change in pressure (or temperature for
temperature switches) is necessary to reset a Nason
snap-action switch to its original electrical state. This
feature prevents “searching” and maximizes switch
and system life. Catalog ranges are typical mid-range
and can be varied with special construction.
Electrical Connections
A wide variety of electrical connectors are readily
available for most applications. Screw terminals, wire
leads, blades, studs, conduit, automotive DIN and
military connectors are stock items.
Media Connections
Nason’s offering of media connections is unmatched
in the industry. NPT, BSP, SAE, JIS, DIN, MS and many others are readily available.
Electrical Circuits
A unique variety of electrical contact arrangements allows the system designer to achieve complex logic at minimal cost. Contact arrangements up to form ZZ and isolated dual set points are available.
Electrical Rating
Most Nason switches are available in a nominal 5 or
10 AMP rating. Gold plated contacts for low current and
25 AMP ratings are also available.
Life
The operational life of a Nason switch is normally in
excess of one million cycles. Operating life depends on
many variables, and specific tests should be run if
marginal conditions exist.
Application
Nason switches are used successfully in a great variety of pneumatic and hydraulic applications. Military vehicles and equipment, aviation, marine, machine tools, farm and construction equipment, process equipment, medical equipment, and industrial machinery are typical applications.
Customization
Nason has the experience and willingness to customize
any switch to meet specific application requirements.
Special media connections, electrical connections, circuitry and construction materials can be designed and produced as needed.
