SWITCH APPLICATIONS

The odds are that Honeywell Sensing and Control can meet your switch demands. Designers of heavy-duty equipment have trusted
Honeywell pressure and vacuum switches for many years in applications that are constantly subjected to harsh environments…from
chemical splashes, salt water, high pressure spikes…we’ve got you covered. Our standard line is quite extensive, but if it is not exactly
what your requirements call for we can modify an existing part or create an original just for you. Honeywell has produced millions of
custom-built switches for automotive, pool and spa, powershift transmissions, anti-skid braking systems, excavator hydraulic systems,
water pump systems, and dental air compressors, to name just a few. Our highly skilled model shop, certified lab and engineering staff
can work with you through the design phase, prototype stage, all the way through to the testing phase. And if time is a crucial factor,
rapid prototyping technology can now allow us to provide you with a sample in days.

WARNING! Suitability of application is responsibility of
user. Extreme heat and vibration should be avoided at
mounting points such as on top of an engine over a hot
manifold. (MAX operation temp 250° F). Always install by
using a wrench on the hex base. Torquing at any other part
of the switch voids the warranty or may cause malfunction.
A Polyimide film diaphragm is utilized in the pressure switch
and is not recommended for use with water. However,
a Teflon diaphragm is available for water applications.
Compatibility with the brass or steel external pressure switch
material is the responsibility of the user.
For maximum operating pressures see appropriate switch
family specifications.
Contact Honeywell Engineering whenever use of switch or
fluid compatibility is questioned.

Set Points from 10-400 psi
5000 Series Ultra Duty Pressure Switch

Honeywell Sensing and Control has designed a high pressure/low set point
pressure switch for applications that see sudden pressure spikes and high
system pressures that can result in early switch failures. This series has been
strengthened to prevent cracking of the base with plated steel and screw
machined components in a 3-piece design. Modifications to the effective
area of the pressure cavity and size of the diaphragm button and diaphragm
o-ring are what makes the switch capable of handling sudden pressure
transients and high system pressures that are common in applications such as
braking, transmission and hydraulic systems.

The switch’s physical appearance is similar to our 5000 Series switches with a
height of only 2.3” (approx) and a diameter of 1.47”. In comparison to our
5000 Series Switch the burst rating has significantly increased from 1250 psi
to over 4000 psi on the new design.
