IEC 60669-1:2017 RLV
Switches for household and similar fixed-electrical installations - Part 1: General requirements
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.

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.
