FEATURES
DESCRIPTION
The Honeywell MICRO SWITCH™ Series of EN limit switches
are bushing mount designed, manufactured, and qualified to
MIL-PRF-8805 standards. These products provide a durable
switch for commercial and military aircraft as well as commercial
and military ground-based equipment. Other applications
include off-road equipment where severe environments are
encountered.
The EN Series of switches have proven to deliver consistent and
reliable operation in harsh environments on critical applications
for more than 65 years.
VALUE TO CUSTOMERS
• Precise and reliable position indication of critical applications
on aircraft and military systems
DIFFERENTIATION
• MICRO SWITCH™ EN Series’ products are highly
configurable; offering a variety of integral actuators, electrical
circuitries, and electrical terminations
• Circuitry options from 1PST (one-pole single throw) circuit to
6PDT (six-pole double throw) circuits for position indication of
different independent circuits or providing redundant circuit
capabilities
• Rugged stainless steel housing and bushing
• All-metal drive train for consistent operating characteristics at
high or low temperatures
• Most EN catalog listings are MIL-PRF-8805 compliant for
stringent military and non-military applications
• MIL-PRF-8805 symbol 4 (resilient) sealing to keep dust, water,
and ice from entering the switch enclosure
• Gold-bifurcated, gold-plated, or silver-alloy switch contacts
for reliably controlling electrical loads from less than 0.5 A [low
energy/logic level] up to 15 A (power duty)
• Wide temperature range from -54 °C to 125 °C [-65 °F to
257 °F] for sea level or high altitude military or commercial
applications
• Assortment of switch actuators and electrical terminations
• Miniature package size [400EN Series and 600EN Series]
reduces housing diameter by 30 % for smaller space required
on equipment
POTENTIAL APPLICATIONS
• Landing gear systems for commercial and military aircraft
including helicopters
- WOW switch (Weight-on-Wheels) for landing gear
- Up-lock and down-lock sensing
- Landing gear bay doors closed/locked
• External doors and hatches for commercial and military
aircraft including helicopters
- Closed and locked indication for passenger entry/exit doors,
cargo bay doors, and/or other doors or hatches (refueling
door, APU air inlet door)
• Military ground vehicles
- Doors or hatches closed/locked or open
• Off-road construction equipment
- Doors or panels present/closed/open
- Up-stop or down-stop limits

MICRO SWITCH™ Environmentally Sealed Limit Switches, EN Series
STANDARD SWITCHES (see pages 4 and 5)
TERMINATION
While the standard EN Series provides a wide variety of products,
Honeywell offers a miniature EN Series and a special EN Series
per the following descriptions.
Termination is specified in the order guides. Leadwires are
generally six feet long, and of the gage and military specifications
noted in the order guides.
MINIATURE SWITCHES (see pages 6 through 8)
MOUNTING
Miniature type EN switches meet the demand for smaller size
and lighter weight without sacrificing performance or electrical
capacity. These types are of the same construction, seal, and
materials as the standard size EN switches.
Plunger actuator switches mount through 5⁄8 in [Ø 0.625 in] or
15⁄32 in [Ø 0.469 in] holes. Lock washer, keyed washer, and wire
lock hexagon mounting nuts lock the switches in their mounting
holes.
Type 400EN switches are directly interchangeable with their
standard size EN counterpart, yet the housings are smaller in
diameter and lighter in weight. The miniature-size housing is 7,92
mm [0.312 in] smaller in diameter, and the switch weighs 9,1 g
[0.3 oz] less.
Rotary-actuated switches mount through 15⁄32 in [Ø 0.469 in]
holes. A lock washer, wire lock hexagon nut, and locating pins on
the top of the housing prevent switch rotation.
Figure 1. Typical EN Switch Construction
SWITCHES WITH SPECIAL REQUIREMENTS
(see page 9)
High velocity actuation
This switch (1EN231-6) is designed to withstand near ‘‘hammerblow’’ actuation as is found in over-center locking mechanisms. It
is dimensionally interchangeable with standard listing 1EN1-6.
Low force operation
Special spring construction within this switch (1EN51-6) reduces
the normal 6 lb to 12 lb (26,7 N to 53,4 N) EN operating force to
3 lb to 6 lb (13,3 N to 26,7 N). This switch is also dimensionally
interchangeable with the standard size 1EN1-6.
Increased overtravel
A longer plunger and bushing on the switch (1EN61-6) extends
the EN overtravel capabilities from the normal 6,35 mm to
21,8 mm [0.25 in to 0.86 in]. The longer bushing also permits
additional adjustment of the plunger position or installations
where an increased bushing length is required.
Figure 2. Circuitry Diagrams
High impact shock
Catalog listing, 1EN75-R3 (M8805/65-001), has been qualified
to MIL-PRF-8805, including high impact shock class H. Other
switches rated for high impact shock applications incorporate
the same plunger mechanism and internal switch design as
used in the 1EN75-R3 and are expected to conform to the same
requirements.

OPERATION
Plunger Actuators
For in-line actuation. An ice scraper ring cleans the actuator with
each operation.
Ball Bearing Plunger Actuators
For random direction operation. An ice scraper ring cleans the
actuator with each operation.
Roller Plunger Actuators
For cam and slide actuation not to exceed 20° rise. Roller adjusts
laterally in 45° increments. An ice scraper ring cleans the
actuator with each operation.
10
sensing.honeywell.com
Roller Linkage Lever Actuators
A threaded rod attaches to the rotary lever for positive actuation.
The rotary lever operates in either direction and adjusts laterally
to any position through 360°. The threaded rod pivots in two
planes. The actuator has no spring return, but is controlled
directly by the movement of the actuating device.
Roller Lever Actuators
For cam and slide actuation with more than a 30° rise. The
actuator is available in clockwise or counterclockwise operation
with a spring-return mechanism. The actuator adjusts laterally to
any position through 360°. The roller is laminated phenolic.
