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

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 IP5x, 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 test are completed in
immediate sequence.
f
Heating and endurance is recommended to be tested on the same specimens. If declared, separate 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 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
EMC testing may require additional specimens 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 5.1.2.

e
Testing shall be completed using either method “a” or method “b”. The same method shall be used for both
“complete switch” and the “contacts only” testing. Switches with series and parallel contacts test shall add the
parallel contact test with the same method “a” or ”b” used for the series contact test. Testing to both method
“a” and method “b” is not required.

226 The switch shall be loaded as specified in Table 103, and connected in accordance with the
227 test circuit in 61058-1: —, Table 2.
228 a) Where, in IEC 61058-1:—, Table 2, an auxiliary switch (A) is symbolized in the test circuit,
229 the tests for the two ON-positions of the specimen (S) are performed on two separate sets
230 of test samples. The connection to the test load to be performed for the two tests is
231 symbolized in IEC 61058-1:—, Table 2 by an auxiliary switch A.
232 b) Multiway switches are loaded according to 61058-1:2016, Table 1. The load for the other
233 switch positions is that resulting from the loads necessary to achieve the conditions
234 specified above.
235 c) For circuits according to IEC 61058-1:—, 7.2.7 for specific lamp load, the connection and
236 test load are as specified by the manufacturer using the maximum occurring inrush current
237 at room temperature. For a specific lamp load, it is recommended that the specimen be

238 operated with loads that are used in the field rather than with synthetic loads. Forced cooling
239 of the specific lamp load may be applied in order to ensure cold resistance for each
240 operating cycle and shorten the test time.
241 d) No electrical load is applied during the endurance tests for switches classified to IEC 61058 -
242 1:—, 7.2.6 with a rating of 20 mA or less.
