Eaton’s Cutler-Hammer® 22.5 mm
Industrial Heavy-Duty Pushbutton line
offers a wide array of functional,
smartly styled illuminated and
nonilluminated 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
frontof-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.

Benefits
Plastic Devices
-
Modular
construction makes assembly
fast and
simplifies stocking of
components and
complete devices
-
Reliability
nibs provide positive contact
through light,
medium or heavy
loads
-
Chrome finish
and plastic construction
are corrosion
resistant
Metal Devices
-
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 installation
cost, time and
inventory
-
Stands up well
in corrosive
environments
-
E22 and EM22
compatibility lowers
parts count and
inventory
requirements
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 contaminants.
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.
