STANDARD BASIC SWITCH CUT-A-WAY
The cut-a-way shown is representative of the standard basic switches described in this
catalog.
GENERAL INFORMATION
MICRO SWITCH standard basic switches
are precision snap-action mechanisms
enclosed in accurately molded plastic
cases. These switches are carefully manufactured and thoroughly inspected.
They are industry known for their compactness, light weight, accurate repeatability and long life.
Mounting holes for Types BZ, BM, BA, BE,
DT, MT, and 6AS switches accept pins or
screws of .139 inch (3,53 mm) diameter.
Characteristics as stated are taken at normal room temperature and humidity.
These may vary as temperature and humidity conditions differ.

MOUNTING DIMENSIONS
Mounting dimensions are included at the
end of each product section. They are
shown in English and metric equivalents.
These dimensions are for reference only.
For exacting layout work, request an engineering layout work, request an engineering drawing from the 800 number.
The type BZ switch design meets most
applications needs. Modifications of the
standard silver contact design and material, spring configuration, and plunger locations give the type BM, BA and BE
switches greater electrical load handling
capacity. Other changes in materials and
switch design provide operating characteristics, temperature tolerances, and
sealing to cover a wide range of special
requirements.

This section covers only over 100 of our most popular BZ/BA type Series
catalog listings. If you don’t find what you’re looking for, it’s likely one of
the approximately 1800 other active listings will meet your needs. Contact the 800 number.
UL/CSA
Our 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 Standard 1054; the BE line is covered as an Industrial Motor
Controller to UL Standard 508.

GENERAL INFORMATION
SPECIAL CIRCUITRY SWITCHES
‘‘Special sequence’’ switches provide unusual circuit control. A make-beforebreak switch provides circuit continuity
while switching from N.C. to N.O. In another make-before-make switch, upon
actuation, one circuit is made an interval
before the second circuit. Another switch
provides a single pulse or momentary
closure of the contacts with each cycle of
operation.
Double break versions can interrupt greater inductive loads and feature shorting
bar construction. A split contact version
allows control of the two isolated circuits.
Characteristics: O.F. – Operating Force;
R.F. – Release Force; P.T. – Pretravel;
O.T. – Overtravel; D.T. – Differential Travel;
O.P. – Operating Position.
