SWITCHES FOR APPLIANCES –
Part 2-4: Particular requirements for
independently mounted 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.

This part of International Standard IEC 61058 has been prepared by subcommittee 23J:
Switches for appliances, of IEC technical committee 23: Electrical accessories.
This standard shall be used in conjunction with IEC 61058-1, Switches for appliances – Part 1:
General requirements (third edition, 2000). It lists the changes necessary to convert that standard
into the IEC standard: Particular requirements for independently mounted switches.
This part constitutes the first edition of IEC 61058-2-4.
This consolidated version of IEC 61058-2-4 consists of the first edition (1995) [documents
23J/132/FDIS and 23J/143/RVD] and its amendment 1 (2003) [documents 23J/253/FDIS and
23J/255/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 1.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
The annex R forms an integral part of this standard.
The annexes S and T are for information only.

61058-2-4  IEC:1995+A1:2003 – 9 –
The committee has decided that the contents of the base publication and its amendment 1 will
remain unchanged until 2007. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
In this part:
a) The following print types are used:
– requirements proper: in roman type;
– test specifications: in italic type;
– explanatory matter: in smaller roman type.
b) Subclauses, figures or tables which are additional to those in part 1 are numbered starting
from 101.

SWITCHES FOR APPLIANCES –
Part 2-4: Particular requirements for
independently mounted switches
1 Scope
This clause of part 1 is applicable except as follows:
1.1 Replacement:
This International Standard applies to independently mounted switches for appliances
(mechanical or electronic) actuated by hand, by foot or by other human activity, to operate or
control electrical appliances and other equipment for household or similar purposes with a
rated voltage not exceeding 480 V and a rated current not exceeding 63 A.
These switches are intended to be operated by a person, via an actuating member or by
actuating a sensing unit. The actuating member or sensing unit can be integral with or
arranged separately, either physically or electrically, from the switch and may involve
transmission of a signal, for example electrical, optical, acoustic or thermal, between the
actuating member or sensing unit and the switch.
Switches which incorporate additional control functions governed by the switch function are
within the scope of this standard.
This standard also covers the indirect actuation of the switch when the operation of the
actuating member or sensing unit is provided by a remote control or a part of an appliance or
equipment such as a door.
NOTE 1 Electronic switches may be combined with mechanical switches giving full disconnection or micro-
disconnection.
NOTE 2 Electronic switches without a mechanical switch in the supply circuit provide only electronic
disconnection. Therefore, the circuit on the load side is always considered to be live.
NOTE 3 For switches used in tropical climates, additional requirements may be necessary.
NOTE 4 Attention is drawn to the fact that the standards for appliances may contain additional or alternative
requirements for switches.
NOTE 5 Throughout this standard, the word “appliance” means “appliance or equipment”.
1.2 This subclause of Part 1 is not applicable
1.3 This subclause of Part 1 is applicable.
1.4 This subclause of Part 1 is not applicable.

Additional subclause:
9.101 Switches operated by means of a removable key or by means of an intermediate part,
such as a cord, a chain or a rod, shall be so designed that the key or intermediate part can
only touch parts which are insulated from live parts.
The key or intermediate part shall be insulated from metal parts of the mechanism, unless the
clearances and creepage distances between live parts and metal parts of the mechanism
have at least the values specified in 20.1.4 and 20.2.4.
Compliance is checked by inspection, by the test of 15.3 and, if necessary, by measurement.

and the tests are then repeated with rigid solid conductors if a solid conductor with the same
cross-sectional area is specified in IEC 60227-3.
Additional subclauses:
11.1.2.101 Terminals classified in 7.2.4 are in general not permitted. Such terminals may
however in particular cases be permitted for the load side of the switch (see 11.1.3).

61058-2-4  IEC:1995+A1:2003 – 21 –
11.1.3.101 The power supply cable shall be connected only by a method of attachment such
that the cable can be replaced without the aid of special purpose tools or by a cable not
requiring special preparation. Connection from the switch to the appliance shall normally be
performed in a similar way, but may in particular cases (e.g. a particular manufactured
connection between the switch and the appliance) be made by a method of attachment such
that the cable can only be replaced with the aid of special purpose tools normally available to
the manufacturer or his agent.
A method of attachment such that the cable cannot be replaced without destroying the
integrity of the switch shall not be used.
