Datasheet
MICRO SWITCH™ Large Premium Basic Switches
Accurate, reliable, and repeatable, MICRO SWITCH™ BZ/BA/BM/BE Series features precise operating characteristics
and enhanced life. These premium, large snap-action switches offer precision operation and sensitive differential
travel.
Utilizing state-of-the-art manufacturing processes and quality controls, Honeywell has engineered premium, large
snap-action switches that meet various international agency requirements. Some models have military qualifications.
MICRO SWITCH™ BZ/BA/BM/BE Series are often used for precision on/off applications, as well as end of limit,
presence/absence, and manual operator interface functions.
Their engineered design is suitable for various application needs. Configured options with BZ, BA, BM, and BE
switches provide a wide variety of operating and interface characteristics.
The MICRO SWITCH™ 6AS Series consists of two large premium BZ/BA/BM/BE snap-action switches ganged
together and actuated by a single actuator. Field adjustable operating point is an option for one or both switches.
What makes our switches better?
• Industry-leading temperature range for options up to 204 °C
[400 °F] and temperatures as low as -55 °C [-67 °F]
• Exclusive current carrying capability of up to 25 A
• International approvals: UL, CSA, ENEC, CE listings
• Options for circuitry, styles, connection types and a wide
selection of actuator styles
• Dependable performance -
tested up to 20 million mechanical cycles
• MICRO SWITCH™ legacy and expertise - over 75 years of
engineering excellence and experience
Operating in extreme
temperatures is
all in a day’s work for
MICRO SWITCH™
large basics!

GLOBAL USE AND APPROVALS
Features
and Benefits
Switches certified to UL, CSA, ENEC, and CE for global use
FLExꢀBꢀLꢀty OF PRODUCt ChARACtERꢀStꢀCS
Honeywell’s large basic switches offer various operating force and differential travel
options to meet the actuator type. Designed with momenꢁarꢂ or mainꢁained
conꢁacꢁ acꢁion, these switches may perform a variety of functions as well as
offering a choice of actuation, termination and operating characteristics for design
fleꢃibiliꢁꢂ
Listings certified for global use and mulitple applications
VARꢀENtS FOR ExtREME CONDꢀtꢀONS
With an IP64 sealing option to maintain switch enclosure sealing, many listings can
be used in dirty, harsh environments with their dusꢁproof and splasꢄ resisꢁanꢁ
seals. Many versions operate in extreme temperatures, up to 121 °C [250 °F],
and several with high temperature options for up to 204 °C [400 °F], as well as
temperatures as low as -55 °C [-67 °F]
EASy ꢀNStALLAtꢀON REDUCES OVERALL COStS
The switch’s enlongated mounting hole allows for easier, more accurate mounting
tꢀGht hyStERESꢀS/DꢀFFERENtꢀAL tRAVEL
Designed with a hysteresis as small as 0,008 mm [0.0003 in], the BZ/BA/BM/
BE switches may be used in applications where very tight and sensitive control is
required between the operate and release points
Standardize switching packages
CURRENt CAPACꢀty FROM LESS thAN 1 A tO 25 A
With a broad current capacity, one swiꢁcꢄ package can conꢁrol a wide range
of elecꢁrical loads. As requirements vary for applications, a standardized switch
package may help reduce costs and increase application flexibility. Gold conꢁacꢁs
available for controlling low energy/low power circuits
ENhANCED PERFORMANCE
Internal flat spring design delivers optimum performance and swiꢁcꢄ reliabiliꢁꢂ

Potential Applications
BUꢀLDꢀNG CONtROLS AND EQUꢀPMENt
Often used in a building’s boiler/heater controls, in HVAC systems to sense exhaust
pressure on high efficiency furnances, and in fire suppression systems to sound
alarm when sprinkler activation/waterflow is detected. May also be used in machine
tools to limit the maxiumum movement for pieces of equipment
DOORS AND LꢀFtS
May be used in elevators and lifts to sense if the car is in position before the door
opens and on door-latching mechanisms to indicate door closed and/or door
locked
SEMꢀ-tRUCꢅS AND tRAꢀLERS
Can be used to disengage the cruise control when the clutch pedal is depressed
and for diesel engine brake assist. For surface transportation equipment, can be
used as a seat switch
VALVES
Detects whether a valve is “open” or “closed”
tꢀMꢀNG DEVꢀCES
Often used in commercial/industrial-grade timers to turn outputs “on” and/or “off” at
preset times
COMMUNꢀCAtꢀON SyStEMS
May be used as a door interlock on communication consoles or enclosures
FOOt SWꢀtChES
In commerical and industrial foot switch enclosures, may be used as the switching
element
COMMERCꢀAL AND ꢀNDUStRꢀAL ꢅꢀtChEN EQUꢀPMENt
May be used to indicate door closed and/or door locked for the self-cleaning feature
ꢀRRꢀGAtꢀON EQUꢀPMENt
Often used for limiting maximum offset of irrigation towers
MEDꢀCAL ꢀNStRUMENtAtꢀON
In medical and dental equipment, often used in foot switches to control the dental
drill and the positioning of the chair

Force required to attain full overtravel of actuator.
Full Overꢁravel Force
Position of switch plunger or actuator at which point contacts snap from normal to operated position. With flex-
ible or adjustable actuators, the operating position is measured from the end of the lever or its maximum length.
Location of operating position measurement shown on mounting dimension drawings.
Operaꢁing Posiꢁion-OP
Amount of force applied to switch plunger or actuator to cause the contact “snap-over.” Note in the case of
adjustable actuators, the force is measured from the maximum length position of the lever.
Operaꢁing Force-OF
Overꢁravel-Ot
Preꢁravel-Pt
Plunger or actuator travel safely available beyond operating position.
Distance or angle traveled in moving plunger or actuator from free position to operating position.
Amount of force still applied to switch plunger or actuator at the moment contacts snap from operated position
to non-operated position.
Release Force-RF
toꢁal travel
Distance from actuator free position to overtravel limit position.
