新的！IEC 60669-1:20 17作为IEC 60669-1:20 17 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60669的这一部分适用于手动操作的通用功能开关，仅用于额定电压不超过440 V、额定电流不超过63 A的交流（AC），用于室内或室外的家用和类似固定电气装置。 对于配有无螺丝端子的开关，额定电流限制为16 A。 这第四版取消并取代了1998年出版的第三版，修正案1:19 99和修正案2:20 06。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更:a)改变电机负载开关的范围； b)删除一些过时的规范性参考文献； c)定义的变更； d)在第5条中，用于试验的试样数量在表1中明确给出（因此删除了IEC 60669-1:19 98的相应附录A）； e)在第5条中，澄清了应在哪些开关上进行第19条的测试； f)包括关于13A开关的要求； g)强制指示端子仅适用于刚性导体； h)柔性导体的要求和试验条件已包含在第12条中； i)包括了对指示灯单元的要求； j)19.3中自镇流灯负载的新测试； k)表20已完全重新绘制，以涵盖正常、微型和微型-间隙开关和重新编号的表21； l)新的信息性附件B，包括为使IEC 60669-1与IEC 60998（所有部分）、IEC 60999（所有部分）和IEC 60228的要求保持一致而计划的未来变更； m)关于19.3电路开发的新资料性附件C； n)新的信息性附件D，包括对绝缘穿孔端子的附加要求； o)新的信息性附录E，包括预期在低于−5°C温度下使用的开关的附加要求和测试。 关键词:家用开关固定电气安装

NEW!IEC 60669-1:2017 is available as IEC 60669-1:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

This part of IEC 60669 applies to manually operated general purpose functional switches, for alternating current (AC) only with a rated voltage not exceeding 440 V with a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors.
For switches provided with screwless terminals, the rated current is limited to 16 A.
This fourth edition cancels and replaces the third edition published in 1998, Amendment 1:1999 and Amendment 2:2006. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

a) change of the scope for motor load switches;    
b) deletion of some dated normative references;
c) changes to the definitions;
d) in Clause 5 the number of specimens to be used for the tests are clearly given in Table 1 (Corresponding Annex A of IEC 60669-1:1998 was therefore deleted);
e) in Clause 5 it was clarified on which switches the tests of Clause 19 shall be carried out;
f) requirements concerning 13 A switches have been included;
g) mandatory indication that a terminal is suitable for rigid conductor only;
h) requirements and test conditions for flexible conductors have been included in Clause 12;
i) requirements for pilot light units have been included;
j) new test for self-ballasted lamp loads in 19.3;
k) Table 20 has been completely redrawn to cover normal, mini and micro-gap switches and renumbered Table 21;
l) new informative Annex B including changes planned for the future in order to align IEC 60669-1 with the requirements of IEC 60998 (all parts), IEC 60999 (all parts) and IEC 60228;
m) new informative Annex C about the circuit development for 19.3;
n) new informative Annex D including additional requirements for insulation-piercing terminals;
o) new informative Annex E including additional requirements and tests for switches intended to be used at a temperature lower than −5 °C.
