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

Features
and Benefits
GLOBAL USE AND APPROVALS
Switches certified to UL, CSA, ENEC, and CE for global use
FLEXIBILITY OF PRODUCT CHARACTERISTICS
Honeywell’s large basic switches offer various operating force and differential travel
options to meet the actuator type. Designed with momentary or maintained
contact action, these switches may perform a variety of functions as well as
offering a choice of actuation, termination and operating characteristics for design
flexibility
Listings certified for global use and mulitple applications
VARIENTS FOR EXTREME CONDITIONS
With an IP64 sealing option to maintain switch enclosure sealing, many listings can
be used in dirty, harsh environments with their dustproof and splash resistant
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 INSTALLATION REDUCES OVERALL COSTS
The switch’s enlongated mounting hole allows for easier, more accurate mounting
TIGHT HYSTERESIS/DIFFERENTIAL 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 CAPACITY FROM LESS THAN 1 A TO 25 A
With a broad current capacity, one switch package can control a wide range
of electrical loads. As requirements vary for applications, a standardized switch
package may help reduce costs and increase application flexibility. Gold contacts
available for controlling low energy/low power circuits
ENHANCED PERFORMANCE
Internal flat spring design delivers optimum performance and switch reliability
MILITARY APPROVALS
MIL-PRF-8805 switches available for military-specified applications

Potential Applications
BUILDING CONTROLS AND EQUIPMENT
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 LIFTS
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
SEMI-TRUCKS AND TRAILERS
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”
TIMING DEVICES
Often used in commercial/industrial-grade timers to turn outputs “on” and/or “off” at
preset times
COMMUNICATION SYSTEMS
May be used as a door interlock on communication consoles or enclosures
FOOT SWITCHES
In commerical and industrial foot switch enclosures, may be used as the switching
element
COMMERCIAL AND INDUSTRIAL KITCHEN EQUIPMENT
May be used to indicate door closed and/or door locked for the self-cleaning feature
IRRIGATION EQUIPMENT
Often used for limiting maximum offset of irrigation towers
MEDICAL INSTRUMENTATION
In medical and dental equipment, often used in foot switches to control the dental
drill and the positioning of the chair

BZ | BA | BM | BE | 6AS Series
6AS SERIES - PREMIUM LARGE SNAP-ACTION TANDEM SWITCH ASSEMBLY
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. Operating characteristics are
dependent upon the type of individual switches and actuators chosen. Field adjustable operating point on one or both basic switches. Solder, A2, and T-type terminations available, along
with straight, roller, and leaf levers. Mounting holes accept pins or screws of 3,53 mm [0.139 in]
diameter. Often used for boiler controls or anywhere two circuits need to be controlled by one
actuator.

OPERATING CHARACTERISTICS
Table 3. Operating Characteristics Definitions

Characteristic
Description
Differential Travel-DT
Plunger or actuator travel from point where contacts “snap-over” to point where they “snap-back.”
Free Position-FP
Position of switch plunger or actuator when no external force is applied.
Full Overtravel Force
Force required to attain full overtravel of actuator.
Operating Position-OP
Position of switch plunger or actuator at which point contacts snap from normal to operated position. With
flexible 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.
Operating Force-OF
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.
Overtravel-OT
Plunger or actuator travel safely available beyond operating position.
Pretravel-PT
Distance or angle traveled in moving plunger or actuator from free position to operating position.
Release Force-RF
Amount of force still applied to switch plunger or actuator at the moment contacts snap from operated position
to non-operated position.
Total Travel
Distance from actuator free position to overtravel limit position.
