PBM Pendant Pushbutton Stations
440/428-1161 • Fax 440/428-7635
The Multi-Purpose PBM Pen-
dant Pushbutton Stations have
been designed to use 22mm
NEMA 4X pushbutton ele-
ments to provide full flexibility.
Spacing of the mounting holes
will permit enlarging the hole
to install the larger 30mm
pushbutton elements if de-
sired. Each enclosure is pro-
vided with a full complement
of standard self-adhesive
nameplates to meet most pen-
dant pushbutton applications.
The multiple screws used for
fastening the front and back
portions of the enclosures pro-
vide rigidity to the enclosures
for added strength to with-
stand operational abuse and
provide a watertight seal.
• Light Weight, Rugged
Molded Enclosures,
“Safety Yellow.”
• Molded-in Stainless Steel
hanger brackets for exter-
nal strain-relief cable. Pro-
visions for internal strain
relief are also provided.

Application
PBM Pendant Pushbutton Stations
are designed for control of electri-
cally powered industrial equip-
ment such as electric overhead
traveling (E.O.T.) cranes or hoists
where one to five speed motors
are used. The lightweight ergo-
nomically designed enclosures fit
comfortably into an operators
hand and yet are built using a
polymer selected to resist shock.
Standard indicator plate mark-
ings (self-adhesive) are included
with each enclosure, but spe-
cial nameplates or markings
can be provided.
Select standard 22mm
NEMA 4X contact elements
from tables or specify the type
required for your completed
control station.
