Product Description
Eaton’s Cutler-Hammer
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 trans-
former, 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 con-
struction 22.5 mm pushbutton devices.
They are an extension of the industri-
ally 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 dura-
ble 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.

Contact Block Operation
Linear make and break. All normally
closed (NC) contacts are Direct Opening
Action, i.e., NC contacts are physically
forced open by direct linkage with the
pushbutton operator in the unlikely
event of contact weld.
The contact block contacts are provided
with “Reliability Nibs.” The precisely
shaped point of the nib, coined on the
silver contact alloy, penetrates dust,
film oxide layers and other contami-
nants. This improves contact reliability
even under dry circuit and fine dust
conditions.
Logic level contact blocks are available
for low power switching — minimum
1 mA @ 5V DC.

Modular construction makes assem-
bly fast and simplifies stocking of
components and complete devices
Reliability nibs provide positive con-
tact through light, medium or heavy
loads
Chrome finish and plastic construc-
tion are corrosion resistant
EM22 is backwards compatible with
E22 operators
Metal mounting nut cuts through
painted surfaces to provide proper
grounding
Hands-free front of panel mounting
reduces installation cost
Mounting flexibility reduces installa-
tion cost, time and inventory
Stands up well in corrosive
environments
E22 and EM22 compatibility lowers
parts count and inventory
