DESCRIPTION
Accurate, reliable, and repeatable, Honeywell MICRO SWITCH
BZ/BA/VBM/BE Premium Series switches are designed and
manufactured for a wide variety of applications with over 75
years of experience. The internal flat-spring design is ideal
for applications requiring precision switch characteristics
and long life. These precision switches are available with
differential travel less than 0,0254 mm [0.001 in].
Catalog listings within these Series of switches are available
to control a wide range of electrical loads from logic level to
power duty switching coupled with a wide variety of integral
actuators. A variety of electrical connections are available to
match the application requirements. These Series of switches
fit the standard 25,4 mm [1.00 in] mounting centers. Select
catalog listings are available with a threaded plunger bushing
panel mounting. Auxiliary actuators are available to increase
the flexibility of the Premium Series switches as well as metal
or plastic enclosures where required. These switches can
be supplied factory gang–mounted (two switches) with an
integral actuator for double pole applications or other circuit
applications.
Most of these switch Series have agency certifications for
global applications. In addition, select catalog listings are
qualified to MILPRF8805 for military applications.

MOUNTING DIMENSIONS
Mounting dimensions are included in this datasheet. They are
shown in English and metric equivalents. These dimensions are
for reference only. Engineering drawings may be accessed via
the Honeywell web site: sensing.honeywell.com.
Mounting holes for Types BZ, BM, BA, BE, and 6AS switches
accept pins or screws of 3,53 mm [0.139 in] diameter.
RECOMMENDED TORQUE
Mounting screws. . . . . . . . . . . . . . . . . . . . . . . . . . . 0,39 Nm [3 in-lb]*
Terminal screws. ............................ 0,45 Nm [4 in-lb]
Panel mount bushing . 0,45 Nm to 0,68 Nm [4 in-lb to 6 in-lb]
*Note: Tightening mounting screws above 0,3 Nm [3 in-lb]
changes operating characteristics and increases the possibility
of cracking the case.
UL/CSA
Honeywell basic switches are Component Recognized by
Underwriters’ Laboratories, Inc. and certified by Canadian
Standards Association. The BA, BZ, and BM line is covered
as Special Use Switches to UL Standard1054; the BE line is
covered as an Industrial Product to UL Standard 508. Agency

MICRO SWITCH Premium Large Basic Switches
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 oper-
ating 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. O.F. Operating force

OPERATING CHARACTERISTICS
Table 3. Operating Characteristic 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.
