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.

The rated current is limited to 16 A maximum for switches provided with screwless terminals.

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

It also applies to switches such as:

- switches incorporating pilot lights,

- electromagnetic remote control switches (particular requirements are given in part 2),

- switches incorporating a time-delay device (particular requirements are given in part 2),

- combinations of switches and other functions (with the exception of switches combined with fuses),

- electronic switches (particular requirements are given in part 2),

- switches having facilities for the outlet and retention of flexible cables (see annex B).

Switches complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 °C, but occasionally reaching 35 °C.
