SUBMINIATURE/MINIATURE BASIC SWITCHES
The U Series of subminiature basic switches are our newest line. The US is the
smallest snap-action switch available. The UX and UM are versatile, low cost,
full featured products with ample electrical capacity in a compact package.
SM subminiature basic switches are a versatile collection of small size and
ample electrical capacities, including 11 amp power load handling and
1
⁄
4
hp
motor load. SX subminiature basic switches are smaller than SM switches,
yet are big in performance and selection. They provide up to 7 amp power
load capacity. V3 miniature basic switches put a 25 amp power load capacity
and a choice of 11 other electrical ratings into a relatively small package with
many choices of actuators, contact materials, and terminal designs. V7 minia-
ture basic switches have electrical ratings up to 15 amps. Both commercial
and European versions are UL recognized and CSA certified. The latter is also
designed to meet all leading European approval agency requirements. TB
miniature basic small double-break units can control 2, 3 or 4 isolated circuits.
STANDARD BASIC SWITCHES
Power load switching and motor handling capacity are among the attractions
of thumb-size BZ/BA standard basic switches. Double-pole double-throw
switching is added by DT switches. Where there’s a need for reliable switch-
ing of high capacity systems involving DC motors and solenoids, MT magnet-
ic blow-out switches do the job. The 3MN has double-break switching. 6AS
assemblies have two tandem mounted standard basic switches under a com-
mon actuator.
SEALED AND HIGH TEMPERATURE BASIC SWITCHES
Specially adapted basic switches include: SE/XE environment-proof switch-
es which protect subminiature SM/SX basic switches within a sealed hous-
ing; HM hermetically sealed switches are interchangeable in operating point
with the SM switches; HS hermetically sealed switches which parallel the size
and mounting scheme of the standard basic switches; and HT high temper-
ature switches for use up to
+1000°F.
DOOR SWITCHES
AC, WW and DM switches automatically cut power when a service door or
drawer is opened.

Basic Switches
Operating Characteristics
ELECTROMECHANICAL SWITCHES
Definitions below explain the meaning of
operating characteristics. Characteristics
shown in tables throughout catalog were
chosen as most significant. They are tak-
en at normal room temperature and hu-
midity. These may vary as temperature
and humidity conditions differ. Sketches
show how characteristics are measured
for in-line plunger actuation.
Linear dimensions for in-line actuation
are from top of plunger to a reference line,
usually the center of the mounting holes.
Differential Travel (D.T.)—Plunger
or ac-
tuator travel from point where contacts
‘‘snap-over’’ to point where they ‘‘snap-
back.’’
Free Position (F.P
.)—Position
of switch
plunger or actuator when no external
force is applied (other than gravity).
Full Overtravel Force—Force
required
to attain full overtravel of actuator.
Operating Position (O.P
.)—Position
of
switch plunger or actuator at which point
contacts snap from normal to operated
position. Note that in the case of flexible or
adjustable actuators, the operating posi-
tion is measured from the end of the lever
or its maximum length. Location of oper-
ating position measurement shown on
mounting dimension drawings.
Operating Force (O.F.)—Amount
of
force applied to switch plunger or actua-
tor to cause contact ‘‘snap-over.’’ Note in
the case of adjustable actuators, the force
is measured from the maximum length
position of the lever.
Overtravel (O.T.)—Plunger
or actuator
travel safely available beyond operating
position.
Pretravel (P
.T.)—Distance
or angle trav-
eled in moving plunger or actuator from
free position to operating position.
Release Force (R.F.)—Amount
of force
still applied to switch plunger or actuator
at moment contacts snap from operated
position to unoperated position.
Total Travel (T.T.)—Distance
from actua-
tor free position to overtravel limit posi-
tion.
