Switches for appliances - Part 2-1: Particular requirements for cord switches (IEC 61058-2-1:2010)

This International Standard applies to cord switches (mechanical or electronic) for appliances 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 250 V and a rated current not exceeding 16 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 or arranged separately from the switch. The transmission of a signal between the actuating member or sensing unit and the switch may be made either physically or electrically (for example electrical, optical, acoustic or thermal). 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.

SWITCHES FOR APPLIANCES –
Part 2-1: Particular requirements for cord switches
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 61058-2-1 has been prepared by subcommittee 23J: Switches

for appliances, of IEC technical committee 23: Electrical accessories.

This second edition cancels and replaces the first edition published in 1992 and its

amendment 1 (1995) and constitutes a technical revision.
The main changes from the first edition are as follows:

Scope, Definitions; Protection against electric shock; Provision for earthing; Construction;

Fire hazard; Abnormal operation and fault conditions for electronic switches; Components

for electronic switches; EMC requirements.

SWITCHES FOR APPLIANCES –
Part 2-1: Particular requirements for cord switches
1 Scope
This clause of Part 1 is applicable except as follows:
1.1 Replacement:

1.1 This International Standard applies to cord switches (mechanical or electronic) for

appliances 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 250 V and a rated current not exceeding 16 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 or arranged

separately from the switch. The transmission of a signal between the actuating member or

sensing unit and the switch may be made either physically or electrically (for example

electrical, optical, acoustic or thermal).

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”.

NOTE An example of the insulation system for earthing continuity is given in Figure 105.

10.3 This subclause does not apply.
Addition:

10.101 The printed conductors of printed circuit boards may be used to provide earthing

continuity under the following conditions:

– at least two tracks are used with independent soldering points and the switch complies

with 10.4 for each track;

– the material of the printed circuit board consists of epoxide woven glass fabric copper-

clad laminated sheet;
– the printed conductors withstand the short circuit test according to 23.3.

11.1.2 Not applicable for rewirable cord switches.
12 Construction
This clause of Part 1 is applicable except as follows:
12.1.2 Addition:

– short rigid wires are not regarded as liable to come away from a terminal, if they remain

in position when the terminal screw is loosened.
Addition:

12.1.101 If solder terminals are classified according to 7.2.12, additional provisions for

securing the conductors shall be provided.

12.3.101 Cord switches shall have cord anchorages such that the conductors are relieved

from strain, including twisting, where they are connected to the terminals, and that the

sheath of the cord is protected from abrasion and kept in position.

12.3.102 It shall be clear how the relief from strain and the prevention of twisting is

intended to be effected.

12.3.103 Makeshift methods such as tying the cord into a knot, or tying the ends with

string shall not be used.

12.3.104 Cord anchorages of cord switches shall be of insulating material, or, if of metal,

be insulated from accessible metal parts or accessible insulating surfaces, by insulation

complying with the requirements for supplementary insulation.

12.3.105 For rewirable cord switches the cord anchorages shall be so designed that their

parts do not fall out when the cover of the switch is removed, even if the switches are not

fitted with their cords.
12.3.106 Cord anchorages shall be so designed that

– for any attachment method, the cord is not fixed by penetration of its insulation in such

a way that the insulation of the cord is cut or otherwise significantly damaged;

NOTE A soft deformation of the insulation in such a way that the insulation of the cord is not cut or otherwise

significantly damaged is allowed.

– the cord cannot touch clamping screws of the cord anchorage if these screws are

accessible or electrically connected to accessible metal parts;

– the cord is not clamped by a screw which bears directly on the cord, except where the

screw is made of insulating material;
– for rewirable switche
