53 Switches for appliances - Part 1-1:
54 Requirements for mechanical switches
56 FOREWORD
57 a) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
58 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
59 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
60 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical
61 Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
62 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt
63 with may participate in this preparatory work. International, governmental and non-governmental organizations
64 liaising with the IEC also participate in this preparation. IEC collaborates closely with the International
65 Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two
66 organizations.
67 b) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
68 consensus of opinion on the relevant subjects since each technical committee has representation from all
69 interested IEC National Committees.
70 c) IEC Publications have the form of recommendations for international use and are accepted by IEC National
71 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
72 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
73 misinterpretation by any end user.
74 d) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
75 transparently to the maximum extent possible in their national and regional publications. Any divergence between
76 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
77 e) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
78 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
79 services carried out by independent certification bodies.
80 f) All users should ensure that they have the latest edition of this publication.
81 g) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
82 members of its technical committees and IEC National Committees for any personal injury, property damage or
83 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
84 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
85 Publications.
86 h) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
87 indispensable for the correct application of this publication.
88 i) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
89 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
90 respect thereof. As of the date of publication of this document, IEC [had/had not] received notice of (a) patent(s),
91 which may be required to implement this document. However, implementers are cautioned that this may not
92 represent the latest information, which may be obtained from the patent database available at
93 https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such patent rights.
94 IEC 61058-1-1 has been prepared by subcommittee 23J: Switches for appliances, of IEC
95 technical committee 23: Electrical accessories. It is an International Standard.
96 This XXX edition cancels and replaces the XXX edition published in [publication_date],
97 Amendment 1:[publication_date] and Amendment 2:[publication_date]. This edition constitutes
98 a technical revision.
99 This edition includes the following significant technical changes with respect to the previous
100 edition:
101 a) .;
102 The text of this International Standard is based on the following documents:

104 the above table.
105 The language used for the development of this International Standard is English [change
106 language if necessary].
107 A list of all parts in the IEC 61058 series, published under the general title Switches for
108 appliances, can be found on the IEC website.
109 In this standard, the following print types are used:
110 – test specifications: in italic type.
111 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
112 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
113 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
114 described in greater detail at www.iec.ch/publications.
115 The committee has decided that the contents of this document will remain unchanged until the
116 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
117 specific document. At this date, the document will be
118 • reconfirmed,

Clause Description Minimum number of Notes
a
specimens for each test
a
Additional specimens may be required depending on the construction and declaration of the switch.
b
Each electrical rating submitted to the testing of Clause 16 and Clause 17 requires an additional 3 specimens
(such as rating i =3 specimens, rating ii = additional 3 specimens).
c
The specimen may be used for more than 1 test, if cumulative stress as a result of sequential testing is avoided.
When a specimen is damaged, a new specimen shall be used for the next test.
d
In general 1 specimen for ingress of solid foreign objects (dust), and 1 specimen for ingress of water. Specific
IP ratings (such as IP 5x, IP6x and protection against water) require a special enclosure to be provided with
the switch specimen in order to complete the testing.
e
The same test specimens are used to complete the testing of 14.3 and Clause 15. The tests are completed in
immediate sequence.
f
Heating according to Clause 16 and endurance according to Clause 17 is recommended to be tested on the
same specimens. If declared, different specimens may be used when noted on the test record.
g
Three additional new specimens may be required according to Clause 20, for the test according to annex G.
h
For testing coatings on printed boards according to clause 20.6, the number of printed boards needed is
determined by the testing of IEC 60664-3.
i
For testing glow wire and ball pressure special test specimens according to 60695-2-11 and 60695-10-2,
respectively may be required.
j
The number of specimens for specific test and examination of Clause 24 is according to the individual
subclasses.
k
Mechanical switches in general do not require EMC testing, however in the event the mechanical switch has
electronic circuitry requiring EMC, additional specimens may be required according to the EMC test program
and switch construction.
l
Abnormal operation and fault conditions are generally destructive, typically the switch cannot be repaired and
reused for the next fault. Specially prepared specimens (such as with wires soldered to the internal circuit)
may be necessary in order to complete the testing. The total number of specimens depends on the switch
construction, for details see Clause 23.
m
This test is part of a sequence, and a new set of 3 specimens shall not be used except as permitted by 5.1.
