22 mm PILOT DEVICES
OMPBD7 SERIES
PUSHBUTTONS AND SELECTOR SWITCHES
Omegas rugged OMPBD7 pilot devices offer
maximum flexibility and a wide choice for all
applications. This 22 mm line is aesthetically
appealing and modularly designed to make
assembly and interchangeability easy.
The OMPBD7 operators are available in
two different body styles to meet every
application need. Both operators exhibit a
new lower profile stylish appearance while
maintaining the rugged performance
necessary for demanding environments.
Two Operator Types
OMPBD7P is a plastic operator with a
captive black plastic front bezel. Constructed
of high-grade thermoplastics, the OMPBD7P
is the corrosion resistant solution for harsh
environments. For super tough applications,
the OMPBD7M has a die-cast zinc housing
and mounting ring for a rugged durability.
Both are finished with corrosion resistant
chrome plating. The OMPBD7M also
features a captive shiny metal bezel for
a polished appearance.
Quick, Easy Installation
A standard anti-rotation tab keeps
front elements from turning or falling
off the control panel, making it possible
for one person to install all OMPBD7
components even if the front and rear
panel are not accessible at the same
time. A central mounting ring allows
for quick installation and removal of
all OMPBD7 operators. All back-of-panel
components including contact blocks
and power module elements snap-on and
are readily accessible and interchangeable
without removing the pilot device from
the panel.
Tool-Less Mounting Latch
The OMPBD7 “tool-less” mounting latch
mates the front element with the contact
blocks and other back-of-panel components.
The mounting latch is available in a plastic
and metal design. The latches are easily
installed with a “click” and removed by
pushing a rotating collar to the right. Quick,
reliable and strong, it’s the best pilot device
mounting latch available in the industry.
Long Electrical and
Mechanical Life
Most OMPBD7 operators have a mechanical
of ten million operations… five million
contact blocks. Electrical life ranges from
500,000 cycles at 3 A to ten million at 0.1 A.
The OMPBD7 line is also electronics
compatible with self cleaning contacts.
Environmental Ratings
Front elements, including pushbuttons,
mushroom operators and selector switches,
are IP66 rated against submersion,
oil and dirt, making them reliable in the
toughest industrial environments. Metal
operators are NEMA 4/13 rated and plastic
operators are rated NEMA 4/4X/13.

Additional Features
and Options
Heavy-Duty Ratings—The OMPBD7 line
is UL 46E, NEMA A600 and Q600 listed.
All components carry a 10 Amp continuous
current rating, covering all industrial
control needs.
All Major Approvals—OMPBD7 front
elements are UL Recognized, while all
OMPBD7 assemblies are UL Approved.
The line is also approved by every major
international agency making them
ideal for export requirements.
H-Bridge & Gold Plated Contacts—
By doubling the available paths for current
to pass through the contacts, the standard
H-bridge design provides a cleaner current
flow. Gold plated contacts quadruple the
current paths for increased contact reliability
in low voltage applications.
Touch-Safe—Back of panel components
are finger safe, with IP20 protection.
Long Lasting Integral LED Assemblies—
Our new LED lamps last up to 11 years!
They are conveniently offered as a complete
unit for all illuminated operators which
include the one piece Integral LED Module.
They come in five different colors: amber,
blue, green, red and white.
