A-deviations
A-deviation: National deviation due to regulations, the alteration of which is for the time being
outside the competence of the CENELEC national member.

This European Standard falls under Directives 73/23/EEC and 89/336/EEC.

NOTE (from CEN/CENELEC IR Part 2:2002, 2.17)  Where standards fall under EC Directives, it is the view of the
Commission of the European Communities (OJ No C 59, 1982-03-09) that the effect of the decision of the Court of
Justice in case 815/79 Cremonini/Vrankovich (European Court Reports 1980, p. 3583) is that compliance with A-
deviations is no longer mandatory and that the free movement of products complying with such a standard should not
be restricted except under the safeguard procedure provided for in the relevant Directive.

A-deviations in an EFTA-country are valid instead of the relevant provisions of the European
Standard in that country until they have been removed.

Electronic switches
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60669-2-1 has been prepared by subcommittee 23B: Plugs, socket-
outlets and switches, of IEC technical committee 23: Electrical accessories.
This fourth edition cancels and replaces the third edition published in 1996, amendment 1
(1997) and amendment 2 (1999). It constitutes a technical revision.
The text of this standard is based on the third edition, amendments 1 and 2, and on the
following documents:
FDIS Report on voting
23B/668/FDIS 23B/682/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
This part of IEC 60669-2 shall be used in conjunction with IEC 60669-1. It lists the changes
necessary to convert that standard into a specific standard for electronic switches.

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 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 electronic switches where the operation or control is made by
physical means, for example, light, 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.
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 1 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 2 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.
