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.
