Electro-Mechanical Switches
Narda offers a complete line of RF/microwave electromechanical switches: stocked SEMs, standard custom
part, and one of a kind custom.
All Narda switches offer exceptional reliability and performance. A unique actuator design enables Narda to
guarantee operation of one million to two million cycles
per switch position without noticeable performance
degradation. This means:
No intermittent contacts in RF or indicator circuits
Operating reliability is complemented by RF specifications that equal or exceed industry standards.
The unique design of the coil and solenoid allows the
solenoid to be actuated more than one million cycles.
These switches can also include a self-termination technique that does not require a separate RF cavity. All
switches are designed to meet MIL-S-3928 and are fully
compatible with both military and commercial logic
integrated circuits.

After assembly, switches are tested for VSWR, insertion
loss, and isolation. Individual switches are then cycled
in each position in accordance with Narda’s comprehensive test procedures to assure trouble-free operation.
Before shipping, final testing is performed. In addition
to electrical and mechanical testing, the switches are
tested at greater than 10 megohms, 500 volts for DC
resistance between the switch body, the terminal, and
indicator circuitry.
Narda electro-mechanical switches are available in
single pole double throw (SP2T) through single pole
twelve throw (SP12T), as well as transfer switch configurations. Standard options include four activation
modes, 50 ohm terminations, and TTL logic circuits.
SEM models have either SMA or Type N connectors,
indicator circuitry, solder-control terminals, 12, 24 or 28
Vdc actuating voltage, and a typical switching speed of
15 ms. TTL models include suppression diodes. Polarity
is common positive for all pulse-latching models.

Introduction
Electro-Mechanical Switches
Custom part switches and one-of-a-kind switches
designed and manufactured to your specific requirements benefit from the same rigorous standards and
environment maintained for our SEM switch line.
SEMs - Standard, Stocked Switches
Narda has brought its most popular custom switches
into the mainstream by making them standard, stocked
catalog products that are always available when you
need them. These Stocked Electro-Mechanical switches
– or SEM switches – are the definitive answer to most
switch requirements.
With nearly forty distinct models, Narda’s SEM switches
address applications in many industries: ATE, satellite
communications, wireless communications, avionics,
and military (Radar/EW/communications and commercial test equipment).
Standard, Custom Switches
Narda custom switches range from single pole, double
throw configurations (SP2T) to single pole, twelve throw
(SP12T) units, plus transfer switches.
Options include four different activation modes, all
popular RF connector types, all common operating
voltages, frequencies up to 26.5 GHz, and such special
www.nardamicrowave.com
E-MAIL: nardaeast@L-3com.com
options as built-in 50-ohm terminations, self de-energizing circuits, indicator circuits, TTL logic circuits,
MOSFET drivers and BCD decoders.
With this wide assortment of options, almost all
requirements can be satisfied without resorting to the
development of one-of-a-kind switches. If you have
unique specifications, however, Narda is ready to design
a switch that will precisely meet each of your parameters.
Extensive implementation of manufacturing and quality
procedures, along with shop flow travelers, ensure that
each step of the manufacturing process is completed
correctly. Registration to ISO9001: 2008 reflects our commitment to serving customers throughout the world.
Assemblies
In many instances, it may be advantageous to have
Narda incorporate a specified switch into a Narda
designed assembly of high performance products, such
as filters, amplifiers, power dividers, and couplers.
Like Narda switches, these assemblies will satisfy your
most rigid performance requirements and will be manufactured, assembled, inspected and tested under the
guidance and regulation of a quality assurance organization without industry equal.

Glossary
All switches are bi-directional. Inputs and Outputs are
interchangeable.
SP2T – A single pole, double throw switch has one input
port and two selectable output ports.
Multiposition Switch – A multiposition switch has one
input port and more than two selectable output ports.
Unlike some switches, Narda models can be switched
directly to any one of the available output positions
without sequencing through intervening positions.
Transfer Switch – A transfer switch has two independent paths that operate simultaneously in one of two
selected positions.
Failsafe – The switch moves to the closed position when
the actuating voltage is applied and always returns to a
predetermined position when the voltage is removed.
Latching – Also called Pulse Latching, the switch
remains in a preselected position whenever the actuating voltage is removed or interrupted and holds
that preselected position until a voltage is applied to
another position. This configuration must be pulse controlled with a pulse width of 20 ms to 100 ms duration.
Standard polarity is common positive.
Normally Open – All output ports of the switch are disconnected from the input port until a voltage is applied
to a selected position.
Terminated Units – Each unused or open output RF
port is internally terminated in a 50-ohm resistive load
(1W CW max.).
www.nardamicrowave.com
E-MAIL: nardaeast@L-3com.com
TTL – Selected position of the switch is controlled by a
TTL Logic High. The switch requires only nominal +28
Vdc (additional 5 Vdc is not required).
TTL Logic Voltage Level:
Low 0 to 0.8 Vdc
High 2.5 to 5.0 Vdc
TTL Logic Input Current:
Low 0 mA
High 1.6 mA max. @ 3.85 Vdc
TTL Units – Transistor-Transistor-Logic circuitry enables
the status of the switch to be controlled by the level of
TTL logic input.
Suppression Diodes – Fast recovery silicon rectifiers (diodes) connected in parallel with the coils of the
switch to suppress any transient voltage that may be
generated by the coils.
Indicator Circuitry – A set of internally mounted contacts that allows external monitoring of switch RF status.
Some switch series include a steering diode drive due
to the electronic indicator.
Solder Terminal – A turret terminal is standard on all
switches.
Self De-energizing Circuitry – With this option, a set
of internally mounted contacts or electronically generated pulses disconnects the driver voltage as soon as
RF contact has been made. This option is only available
with latching type switches. Suppression diodes must
be specified with this option.
