Foreword

The text of the International Standard IEC 60669-2-1:2002, prepared by SC 23B, Plugs,

socket-outlets and switches, of IEC TC 23, Electrical accessories, together with the common

modifications prepared by the Technical Committee CENELEC TC 23B, Switches for household

and similar fixed electrical installations, was submitted to the formal vote and was approved by

CENELEC as EN 60669-2-1 on 2004-07-01.
This European Standard supersedes EN 60669-2-1:2000 + A2:2001 + IS1:2004.

This part 2-1 of EN 60669 is to be used in conjunction with EN 60669-1:1999. It lists the changes

necessary to convert that standard into a specific standard for electronic switches.

The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-07-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-07-01

This European Standard was prepared under a mandate given to CENELEC by the European

Commission and the European Free Trade Association and supports the essential requirements

of Directive 89/336/EEC.
Annexes ZA, ZB and ZC have been added by CENELEC.

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.
Clause Deviation
13.103 Denmark
(Stærkstømbekendtgørelsen- Elektriske Installationer 2001, § 521.7.4)

The insulation of external flexible cable shall comply with or be at least electrically

and mechanically equivalent to that of flexible cables according to HD 21 or HD 22.

Table 52F)

The insulation of external flexible cable shall comply with or be at least electrically

and mechanically equivalent to that of flexible cables according to HD 21 or HD 22.

Norway
(DSB: FEL 1998 §28 and §10, NEK 400:2002 Clauses 520.1 and 521.1 and
Table 52A)

Cables with basic insulation are not accepted as wiring external to the switch. The

insulation of external flexible cable shall comply with or be at least electrically and

mechanical equivalent to that of flexible cables according to HD 21 or HD 22.

Cables complying with the electric strength test only are regarded as internal cables

and are accepted to be installed in enclosures, conduits, ducting and trunking
systems and the like.
Sweden
(ELSÄK-FS: 1999:5, Clauses 520.1 and 521.1 and Table 52-1)

Cables with basic insulation are not accepted as wiring external to the switch. The

insulation of external flexible cable shall comply with or be at least electrically and

mechanical equivalent to that of flexible cables according to HD 21 or HD 22.

Cables complying with the electric strength test only are regarded as internal cables

SWITCHES FOR HOUSEHOLD AND SIMILAR
FIXED ELECTRICAL INSTALLATIONS –
Part 2-1: Particular requirements –
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.
