E22/EM22 Pilot Devices
Product Description
Eaton’s Cutler-Hammer®
22.5 mm industrial heavy-duty
pushbutton line offers a wide
array of functional, smartly
styled illuminated and non-
illuminated pushbuttons,
selector switches, push-pulls,
alternate action and twist-
to-release operators. The
complete line also includes
transformer, full voltage,
resistor, LED or neon
light units.
E22 operators are available
with either a traditional
chrome or matte black front-
of-panel appearance. The
space-saving design and
modular construction of
the E22 line makes on-
the-job assembly fast and
simplifies the stocking
of both components and
complete devices.
Eaton’s Cutler-Hammer
EM22 metal series is a
rugged line of metal
construction 22.5 mm
pushbutton devices. They
are an extension of the
industrially proven E22 heavy-
duty double insulated 22.5
mm pushbutton family.
EM22 operators are
heavy-duty zinc die-cast
construction plated with
a corrosion-resistant
chromate finish. Operators
are complete with a very
durable chrome-plated metal
bezel. Indicating light units
in the EM22 series feature
smartly styled round
lenses that enhance their
appearance and brightness.
All EM22 operators are
compatible with existing E22
contact blocks, light units,
accessories and enclosures.
EM22 metal operators and
indicating lights are grounded
when mounted to metal
panels through the toothed
mounting nut. They are not
grounded when mounted to
plastic panels.
Product History
E22 was first sold in 1983.
The line has had one major
change in the mid 1990s to
increase the size of the
button plates to be roughly
equivalent to a 30mm
pushbutton. Then in 2002,
the EM22 extension of the
line was introduced. Since
then, only minor changes/
additions have occurred.
While the entire product
breadth is not available
anymore as aftermarket,
most functionality is available
in the products shown in this
catalog.
