The 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. The EM22
Metal Series is a rugged line of metal
construction 22.5 mm (0.88”) pushbutton
devices. The devices are an extension of
the industrially proven E22 Series heavy­duty double insulated 22.5 mm pushbutton
family. EM22 Series operators are heavy­duty 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 Series
operators are compatible with existing
E22 Series contact blocks, light units,
accessories and enclosures. EM22 Series
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.
