SWITCHES FOR HOUSEHOLD AND

Part 2-5: Particular requirements –
Switches and related accessories for use in home
and building electronic systems (HBES)
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.

International Standard IEC 60669-2-5 has been prepared by subcommittee 23B: Plugs,

socket-outlets and switches, of IEC technical committee 23: Electrical accessories.

The text of this standard is based on the following documents:
FDIS Report on voting
23B/1110/FDIS 23B/1129/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 2.

This part of IEC 60669 is partially based on IEC 60669-1:1998, its Amendment 1:1999 and

Amendment 2:2006 and IEC 60669-2-1:2002 and its Amendment 1:2008. In cases where

parts of these standards apply, this will be mentioned explicitly by a normative cross-

reference describing the extent to which the referenced element (clause, subclause, figure,

table, etc.) applies. Subclauses, figures, tables or notes which are additional to those in

IEC 60669-1 and IEC 60669-2-1 and their amendments are numbered starting from 101 and

201 respectively, additional annexes are lettered AA, BB, etc.

This part of IEC 60669 lists the changes necessary to convert those standards into a specific

standard for home and building electronic systems (HBES) switches and related accessories.

In this standard, the following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– notes: in smaller roman type.

A list of all parts in the IEC 60669 series, published under the general title Switches for

household and similar fixed-electrical installations, can be found on the IEC website.

The following differences exist in the countries indicated below.
– Clause 26: all CENELEC countries.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

that it contains colours which are considered to be useful for the correct

understanding of its contents. Users should therefore print this document using a

colour printer.

SWITCHES FOR HOUSEHOLD AND
SIMILAR FIXED ELECTRICAL INSTALLATIONS –
Part 2-5: Particular requirements –
Switches and related accessories for use in home
and building electronic systems (HBES)
1 Scope

This part of IEC 60669 applies to HBES switches with a working voltage not exceeding 250 V

a.c. and a rated current up to and including 16 A for household and similar fixed electrical

installations either indoors or outdoors and to associated electronic extension units.

It applies to:

– HBES switches 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 (e.g. those used in ventilating

fans) and for other purposes (e.g. heating installations);

– sensors, actuators, switched-socket-outlets, associated electronic extension units, etc.

In the present standard the word "HBES switch" is applied to describe all kinds of HBES

devices e.g. switches, sensors, actuators, switched-socket-outlets, associated electronic

extension units, etc.
The operation and control are performed:

– intentionally by a person via an actuating member, a key, a card, etc., via a sensing

surface or a sensing unit, by means of touch, proximity, turn, optical, acoustic, thermal;

– by physical means, e.g. light, temperature, humidity, time, wind velocity, presence of

people;
– by any other influence;
and transmitted:

– by an electronic signal via several media, e.g. powerline (mains), twisted pair, optical

fibre, radio frequency, infra-red, etc.

HBES switches complying with this standard are suitable for use at ambient temperatures not

normally exceeding 25 °C, but occasionally reaching 35 °C.

This part of IEC 60669also applies to mounting boxes for HBES switches, with the exception

of those for flush-type HBES switches which are covered by IEC 60670-1.

NOTE 1 In the following country flush mounted boxes are covered by both EN 60670-1 and BS 4662: UK

Functional safety aspects of HBES switches are not covered by this standard. Functional

safety requirements are covered by the standards of the devices which are controlled by the

HBES.

In locations where special conditions prevail, e.g. higher temperature, special constructions

may be required.

NOTE 2 This standard is not intended to cover devices falling within the scope of IEC 60730.

---------------------- Page: 8 ----------------------
60669-2-5 © IEC:2013 – 7 –

NOTE 3 Within this Part 2-5, for any reference to IEC 60669-2-1 and its Amendment 1:2008, the term “electronic

switches” is replaced by “HBES switches”.

NOTE 4 In the following country, HBES switches complying with this standard are suitable for use at ambient

temperatures not normally exceeding 35 °C, but occasionally reaching 40 °C: CN.
