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