Better under pressure. For years, manufacturers and operators
of heavy-duty equipment have trusted Honeywell pressure and
vacuum switches. They��re proven under pressure, in applications
constantly under attack from chemical splashes, performance
spikes and other harsh environments. These switches sense
a change in the pressure or vacuum, opening or closing an
electrical circuit when the designated point is reached.
FEATURES
PRESSURE SWITCHES
1000 Series.
Features: Low set point: actuates at 20 psi
• Reduced part count • High burst rating •
Banjo bolt fitting • Sealed to IP65
Benets: Small, low-cost switch actuated
by hydraulic fluid or gas. Excels in harsh
environments such as extreme weather
conditions or particle-filled areas.
Applications include small vehicle brake
light actuation, compact agricultural
tractors, utility vehicles, trucks and lift
trucks, and small self-propelled vehicles.

Benets: Extends equipment uptime
and life, provides resistance to
corrosion, reduces service costs, and
protects equipment and operators.
Configurability simplifies the design-in
process, eliminates tooling costs, and
reduces manufacturing labor costs.
Durability allows for use in many tough
applications. Potential applications
include agricultural machinery, boilers,
CNC machines, compressors, food &
beverage equipment, fracking equipment,
generators, HVAC/R equipment, heavy
duty construction machinery, heavy duty
trucks, lawn & garden, marine vessels,
material handling machinery, mud pumps,
pneumatic equipment, presses and
punches, pressure washers, railway, trash
compactors, water pumps, and water jet
cutting equipment.
