FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

readability.

---------------------- Page: 12 ----------------------

SIST EN 62047-5:2011
62047-5  IEC:2011 – 7 –
3.1 Switching operation
3.1.1
capacitive switch
switch whereby an RF signal is passed or blocked by a change of impedance ratio caused by
the capacitive effect of making contact using a movable metal plate onto a dielectric film
presented on a fixed metal plate
3.1.2
d.c. contact switch
switch whereby an RF signal is passed or blocked by a movable metal contact
3.2 Switching configuration
3.2.1
series switch
switch whereby an RF signal applied to the input port is directly passed to the output port
when a movable plate makes contact with a fixed plate
3.2.2
shunt switch
switch whereby an RF signal applied to the input port is passed to the ground plane when a
movable plate makes contact with a fixed plate
3.3 Actuating mechanism
3.3.1
electro-statically actuated switch
switch whereby a moving contact is pulled down onto the fixed plate by an electrostatic force
caused by the applied d.c. bias voltage, the moving plate returns to its original position when
the bias voltage is removed
NOTE Advantages are virtually zero power consumption, small electrode size, relatively short switching time, and
relatively simple fabrication and disadvantage is higher actuation voltage.
3.3.2
electro-magnetically actuated switch
switch whereby a movable plate or armature is pulled down onto a fixed plate by a magnetic
force generated by a permanent magnet or an energised electromagnet
NOTE Advantage is a low actuation voltage and disadvantages are complexity of fabrication and high power
consumption.
3.3.3
electro-thermally actuated switch
switch whereby a movable plate constructed of two or more differing materials with differential
thermal expansion coefficients deflects to contact a fixed plate or electrode
NOTE Advantages are nearly linear deflection-versus-power relations and environmental ruggedness and
disadvantages are high power consumption, low bandwidth, and relatively complex fabrication.
3.3.4
piezo-electrically actuated switch
switch whereby a movable constructed of piezoelectric materials deflects to contact a fixed
plate or electrode

SIST EN 62047-5:2011
– 8 – 62047-5  IEC:2011
3.4 Switching network configurations
3.4.1
single-pole-single-throw switch
SPST
device with a single input and a single output, which is providing an ON-OFF switching
function with switch actuation
3.4.2
single-pole-double-throw switch
SPDT
device with a single input and two outputs, which is transferring the through connection from
one output to the other output with switch actuation
3.4.3
single-pole-multi-throw switch
SPMT
device with one input and multiple outputs whereby connection to one or the other of the
multiple outputs is determined by switch actuation
3.4.4

DPDT
device with two inputs and two outputs, which is transferring the through connection from one
output to the other output with switch actuation
3.4.5
multi-pole-multi-throw switch
MPMT
device with multi inputs and outputs, which is transferring the through connection from multi
outputs to the other multi outputs with switch actuation
3.5 Reliability (performance)
3.5.1
life time cycles
number of actuating times which the switches are operating with satisfactory electrical
performances in the on/off positions
NOTE Unlike the electronic switch, a mechanical switch may fail due to stiction (micro-welding and material
transfer) of a moving part and degradation of metal to metal contact used, whereas at electronic RF switches
(capacitive switch) the reliability is limited by dielectric charging (charge injection and charge trapping).
3.5.2
cold switching
performed switching where the RF power is not applied during the switch operation
NOTE It is useful for examining the durability of the switch electrode to see if it can withstand the physical
stresses of repeated switching.
3.5.3
hot switching
performed switching where the RF power is applied during the switch operation
NOTE The hot-switching tests are indicative of how the switch will survive under actual operating conditions, with
current flowing through the device.
