INTERPRETATION SHEET 1

This interpretation sheet has been prepared by subcommittee 23B: Plugs, socket-outlets and

switches, of IEC technical committee 23: Electrical accessories.
The text of this interpretation sheet is based on the following documents:
ISH Report on voting
23B/1012/ISH 23B/1030/RVD

Full information on the voting for the approval of this interpretation sheet can be found in the

report on voting indicated in the above table.
___________
Interpretation of the application of IEC 60669-2-1:2002, Subclause 26.2.1,
NOTE 2
According to NOTE 2 of 26.2.1 of IEC 60669-2-1:2002, independent dimmers for
incandescent lamps up to and including 1 000 W are not tested according to
IEC 61000-3-2.
Dimmers according to IEC 60669-2-1 are independent dimmers.

If they are designed to dim different kinds of loads including incandescent lamps they are

considered as dimmers for incandescent lamps and according to IEC 61000-3-2 they need not

to be tested with all different kinds of load.

As a consequence independent dimmers complying with IEC 60669-2-1 and designed to dim

different kinds of loads including incandescent lamps need not to be tested according to

Clause 7 of IEC 61000-3-2:2005 and its Amendments 1:2008 and 2:2009, if the rated power is

less than or equal to 1000 W.

NOTE This interpretation sheet will be withdrawn once IEC 61000-3-2 will have been modified to cover also

dimmers for other kinds of loads than incandescent lamps.

Interprétation de l’application de la CEI 60669-2-1:2002, Paragraphe 26.2.1,
NOTE 2

Selon la NOTE 2 de 26.2.1 de la CEI 60669-2-1:2002, les variateurs indépendants pour

lampes à incandescence jusqu’à 1 000 W inclus ne sont pas vérifiés selon la CEI 61000-3-2.

Les variateurs selon la CEI 60669-2-1 sont variateurs indépendants.

S’ils sont conçus pour faire varier différentes types de charges inclus des lampes à

incandescence, ils sont considérés comme des variateurs pour lampes à incandescence et

selon la CEI 61000-3-2 ils n'ont pas besoin d'être vérifiés avec toutes les différentes types de

charge.

En conséquence les variateurs indépendants conformes à la CEI 60669-2-1 et conçus pour

faire varier différentes types de charge, lampes à incandescence inclus, n'ont pas besoin

d'être vérifiés selon l'Article 7 de la CEI 61000-3-2:2005 et ses Amendements 1:2008 et

2:2009, si la puissance assignée est moins de ou égale à 1000 W.

NOTE Cette feuille d’interprétation sera retirée une fois que la CEI 61000-3-2 aura été modifiée pour inclure aussi

les variateurs pour les autres types de charge que les lampes à incandescence.

SWITCHES FOR HOUSEHOLD AND SIMILAR
FIXED ELECTRICAL INSTALLATIONS –
Part 2-1: Particular requirements –
Electronic switches
1 Scope
This clause of part 1 applies except as follows.
Replacement:

This standard applies to electronic switches and to associated electronic extension units for

household and similar fixed electrical installations either indoors or outdoors.

It applies to electronic switches for a.c. only, for the operation of lamp circuits and the control

of the brightness of lamps (dimmers) as well as the control of the speed of motors (for

example, those used in ventilating fans) and for other purposes (for example, heating controls),

with a rated voltage not exceeding 250 V and a rated current not exceeding 16 A.

The operation and/or control as mentioned above are performed by a person via an actuating

member, a sensing surface or a sensing unit, by means of touch, proximity, turn, optical,

acoustic, thermal or any other influence.

This standard also applies to general purpose electronic switches with included automatic

functions where the operation and/or the control is initiated by a change of a physical quantity,

for example light, temperature, humidity, time, wind velocity, presence of persons, etc.

This standard also applies to boxes for electronic switches, with the exception of mounting

boxes for flush-type electronic switches.

This standard also applies to electronic RCS and electronic TDS with a rated voltage not

exceeding 440 V and a rated current not exceeding 25 A, intended for household and similar

fixed electrical installations, either indoors or outdoors.

NOTE 1 Switches including only passive components such as resistors, capacitors, inductors, PTC and NTC

components, varistors, printed wiring boards and connectors are not considered as electronic switches.

NOTE 2 Electronic switches may have control circuits with a.c. or d.c. rated control voltages.

Electronic switches complying with this standard are suitable for use at ambient temperature

not normally exceeding 25 °C but occasionally reaching 35 °C.

In locations where special conditions prevail, such as in ships, vehicles and the like and in

hazardous locations, for example, where explosions are liable to occur, special constructions

may be required.

NOTE 3 This standard is not intended to cover devices which are designed to be incorporated in appliances or are

intended to be delivered together with a specific appliance and which are within the scope of IEC 60730 or

IEC 61058-1.
Examples of designs of electronic switches and functions are shown in annex AA.

NOTE 4 Electronic switches without a mechanical switch in the main circuit do not provide a “full off-state”.

Therefore, the circuit on the load side should be considered to be live.

3.105
semiconductor switching device

switching device designed to make or break the current in an electric circuit by means of the

controlled conductivity of a semiconductor in that circuit

NOTE 1 In a circuit where the current passes through zero (periodically or otherwise) the effect of “not making” the

current following such a zero value is equivalent to breaking the current.
NOTE 2 Typical examples of semiconductor switching devices are:

− electronic switching devices using the phase-cut-on principle to control the load by electronic switching on the

current at any phase angle at or after zero crossing in each half-wave, for example, by a thyristor;

− electronic switches using the phase-cut-off principle to control the load by switching off the current at any phase

angle after zero crossing in each half-wave, for example, by a transistor in a diode bridge.

3.106
electronic momentary contact switch

electronic switch with an electromechanical switching mechanism or a semiconductor switching

device which returns automatically to the initial state after operation
3.107
mechanical control
