MICRO SWITCH™
Pushbutton Switches
Line Guide
Pushing industry innovation.
Honeywell Sensing and Control
(S&C) is the global leader in switching products. So you can
be sure we offer the most comprehensive line of pushbutton
switches — including touch feedback, short travel, panel sealed,
watertight, hermetically sealed, and miniature switch series.
Excelling in applications ranging from light industrial to aerospace,
these switches are compact, durable, and offer up to four
poles — with momentary and alt-action, and with a choice of
different colors, shapes and termination options. FAA and PMA
approved listings are also offered, as well as listings with military
specifications.
FEATURES
MICRO SWITCH™
PUSHBUTTON SWITCHES
PB Series.
Features:
Compact size • Up to four
poles • Sealed versions available • 48 oz
max. operating force • Expected 50000
operations of mechanical life
• Hermetically sealed pushbuttons are
corrosion resistant per MIL-PRF-8805/23
and meets explosion proof requirements of
MIL-PRF-8805/23
Benefits:
Switches are available designed
as touch feedback, short travel, panel-
sealed, hermetically sealed, and miniature
sized. Potential applications include
manual operations, such as control
boards and panels in industrial and test
equipment, computer mainframes and
peripherals, process control, medical
instrumentation, and flight deck controls.
AML Series.
Features:
1-, 2-, or 4-poles • Silver or
gold contacts • Full guard bezel option •
Momentary or two-level alternate action
(push-on, push-off) • Electronic and
power-duty control • Snap-in surface
mount or sub-panel (hidden bezel) mount
with mounting hardware • Lamps can be
furnished installed or ordered separately •
Lamp circuit independent of switch circuit
• Optional diode protection for LEDs •
4.5 Vdc to 24 Vdc LED devices have an
internal resistor to maintain current at
nominal 20 mA
Benefits:
AML offers a choice of five
legend sizes, four button heights, full-
or-split section display, and illumination
by incandescent lamps, LEDs or neons.
Accommodates different functions
and promotes operator efficiency. All
terminations at the same shallow depth
(43,1 mm [1.7 in]) for convenient wiring
or PC board termination. Potential
applications include manual operations,
such as control boards and panels in
industrial and test equipment, computer
mainframes and peripherals, process
control, and medical instrumentation.
MML Series.
Features:
1- or 2-poles • Silver or gold
contacts • Printed wiring board (PWB)
or panel-mounted switches • Momentary
or two-level alternate action (push-on,
push-off) • Electronic, and power-duty
control • Snap-in surface mount or sub-
panel (hidden bezel) mount with mounting
hardware • Multi-unit strip mounting
available • Single-level termination
• Tactile feedback • Coordinated
appearance enhances panel harmony
• Illumination by long-life LEDs and
incandescent lamps
Benefits:
Complements AML pushbuttons
and indicators with flexibility and
design freedom for miniature manual.
Breadth of line offers complete selection
of pushbuttons and indicators to
accommodate different functions and
promote operator efficiency. Potential
applications include manual operations,
such as control boards and panels in
industrial and test equipment, computer
mainframes and peripherals, process
control, and medical instrumentation.

MICRO SWITCH™ Pushbutton Switches Line Guide
The lineup of the leader.
Line up behind Honeywell
S&C quality and performance,
found in each pushbutton
switch we offer:
Touch feedback:
These
momentary and alternate
action switches offer a
compact size and up to four
poles.
Short travel:
Resembling the
touch-feedback design, these
switches have a flexible leaf
actuator for lower operating
force and shorter button travel.
Panel sealed:
An elastomer
seal is bonded between
actuating plunger and button
collar — a two-piece design
that enables buttons mounting
separately. After wiring, the
unit snaps into place from
behind the panel.
Watertight:
Facenut-to-
panel, button-to-facenut, and
bushing-to-facenut sealing
prevents entry of water from
the back of panels or over
bushing walls. Switch units are
potted in corrosion resistant
metal enclosures.
Hermetically sealed:
These
switch units feature metal-to-
metal fusion around the cover,
actuator base and mounting
holes. Terminals are sealed
glass-to-metal, while vapor-
proof construction enables
use in damp locations without
condensation on contacts.
Miniature size:
These
momentary action switches
offer steel buttons for use
under hinged plates or paddle
levers.
