MICRO SWITCH™ NT Series
Commercial-Grade Toggle Switches
Honeywell MICRO SWITCH™ NT Series toggle switches meet the need for a rugged, cost-effective toggle switch.
Quality construction features include a seal between the toggle lever and bushing, and between the cover and case.
These switches are suitable for applications in many demanding outdoor environments, where the panels are sub-
jected to vibration from equipment, temperature extremes, dust, splashing water, and/or hose directed water.
They are capable of withstanding exposure to heavy accumulations of early morning dew that may condense on the
control panel in cabs of vehicles left outdoors overnight. The NT toggle switches with larger standard metal or plastic
levers are well suited for gloved-hand operation.
Available in both step-base and flat-base styles, the NT Series offers three popular styles of termination: 6-32 screws,
solder lugs with 3,0 mm [0.12 in] diameter hole, or 6,35 mm [0.25 in] quick connect terminals.
The optional “Easy Start” threaded bushing enables quick alignment of the mounting nut to minimize any cross
threading. The panel stand-off with O-ring feature available on some listings eliminates the need for behind-the-panel
hardware, provides a uniform panel height, and a panel-to-cover seal.
What makes our switches better?
NEMA 3, 3R, 4, 13 and IP67/68 environmental sealing for
demanding applications
UL recognized, CSA certified, and CE certified for global use
1-, 2-, and 4-pole options to meet a variety of circuitry
requirements
2- or 3-position maintained and momentary action to meet
circuit and actuator requirements
Optional step-case design provides added space between
terminals to prevent shorting
Tough environmental sealing
makes harsh environments seem
like just another sunny day.

Features
and Benefits
SEALED TO NEMA 3, 3R, 4, 13 AND IP67/IP68 FOR GLOBAL USE
MICRO SWITCH™ NT toggle switches feature a moveable seal between the
toggle lever and bushing and a completely sealed case to meet
NEMA and IP
seal ratings.
They are suitable for applications in many
demanding outdoor
environments,
where the panels are subjected to vibration from equipment,
temperature extremes, dust, splashing water, and/or hose directed water. UL
recognized, File E12252, Vol. 1, Section 44, CSA certified, and CE certified for
global use
Excellent tactile feedback
WELL-SUITED FOR GLOVED-HAND OPERATION
Spring-loaded actuating mechanism
provides excellent tactile feedback for
the toggle switch lever. The NT toggle switches with larger standard metal or
plastic levers are well suited for gloved-hand operation
Locking levers reduce unintended actuation
LOCKING LEVERS
Optional
lever locks
(pull-to-unlock) require two separate actions to actuate the
switch in order to prevent unintended actuation
MINIMIZES INSTALLATION TIME
Optional flat base case design with a quick connect terminal pattern mates to a
commercial-type connector for
plug-and-play connectivity,
reducing installation
time
VARIETY OF CIRCUITRIES AND OPERATING ACTIONS
NT Series’
2- and 3-position, maintained and momentary
toggle action, for
a breadth of circuitry and actuator requirements. Delivers high performance in a
wide range of temperatures: -40 °C to 71 °C [-40 °F to 160 °F]
EASILY CONTROLS LOW-VOLTAGE DC APPLICATIONS
Toggle switches available with a choice of
silver alloy or gold-plated contacts
to handle a variety of electrical load requirements
INNOVATIVE PRODUCT DESIGN
Optional engineered step-design case provides added space between terminals
to
prevent shorting.
Optional panel stand-off with O-ring panel seal
eliminates
behind-the-panel hardware

Potential Applications
AERIAL PLATFORM LIFTS
Momentary toggles are used to operate the movement of aerial platform lifts. Toggle
can be used to raise & lower, extend & retract and rotate platform or outriggers.
PLATFORM LIFTS FOR TRUCKS
Used to fold/unfold and raise/lower from a lift gate’s control panel.
INDUSTRIAL EQUIPMENT
Used in the control panel of overhead cranes and factory floor equipment.
RAILROAD LOCOMOTIVES AND MAINTENANCE EQUPMENT
Designed into control panels often found in locomotives, rail grinders, tie removal,
ballast spreaders, and tampers.
CONSTRUCTION EQUIPMENT
Used to operate movement of machinery and/or turn on lights, pumps, etc. in road
milling, road pavers, trenchers, stump cutting and other construction and mining
equipment. Also widely used for remote control of concrete pumping and drilling
machines.
AGRICULTURAL MACHINERY
Used in control panels for harvesting equipment, grain handlers, and grain dryers.
