catalog.
GENERAL INFORMATION
MICROSWITCHstandardbasicswitches
are precision snap-action mechanisms
enclosed in accurately molded plastic
cases. These switches are carefully man-
ufactured and thoroughly inspected.
They are industry known for their com-
pactness, light weight, accurate repeata-
bility and long life.
The type BZ switch design meets most
applications needs. Modifications of the
standard silver contact design and mate-
rial, spring configuration, and plunger lo-
cations give the type BM, BA and BE
switches greater electrical load handling
capacity. Other changes in materials and
switch design provide operating charac-
teristics, temperature tolerances, and
sealing to cover a wide range of special
requirements.

Panel mount bushing .......4-6in./lbs.
*Note: Tightening mounting screws
above 3 in./lbs. changes operat-
ing characteristics and increases
the possibility of cracking the
case.

GENERAL INFORMATION
SPECIAL CIRCUITRY SWITCHES
‘‘Specialsequence’’switchesprovideun-
usual circuit control. A make-before-
break switch provides circuit continuity
while switching from N.C. to N.O. In an-
other 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.
Doublebreakversionscaninterruptgrea-
ter 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;
