scope:

Replacement of the first three paragraphs by the following new text:

This part of IEC 60669 applies to manually operated general purpose switches, for a.c. only with a rated voltage not exceeding 440 V and 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.

Switches covered by this standard are intended for the control in normal use of:

- a circuit for a tungsten filament lamp load; or

- a circuit for a fluorescent lamp load (including electronic ballast); or

- a circuit for a substantially resistive load with a power factor not less than 0,95; or

- a monophase circuit for motor load with a rated current up to 10 A and a power factor not less than 0,6; or

- a combination of these.

^{NOTE 1 An extension of the scope to switches for rated voltages higher than 440 V is under consideration.}

^{NOTE 2 An increase of the rated current of 10 A for motor load is under consideration.}

^{NOTE 3 For the time being, switches with a rated current more than 10 A are considered as a 10 A current for motor load switch.}

The standard also applies to boxes for switches, with the exception of mounting boxes for flush type switches.

Renumbering of notes 2, 3 and 4 as notes 4, 5 and 6.

In the 4th paragraph, addition of the word "relevant" before the words "part 2" in the 2nd, 3rd and 5th dashed texts.

Addition at the end of the 4th paragraph of the following dashed text:

-  isolating switches (particular requirements are given in the relevant Part 2)
