This clause of part 1 applies except as follows.
Replacement:
This standard applies to electronic switches and to associated electronic extension units for
household and similar fixed electrical installations either indoors or outdoors.
It applies to electronic switches for a.c. only, for the operation of lamp circuits and the control
of the brightness of lamps (dimmers) as well as the control of the speed of motors (for
example, those used in ventilating fans) and for other purposes (for example, heating controls),
with a rated voltage not exceeding 250 V and a rated current not exceeding 16 A.
The operation and/or control as mentioned above are performed by a person via an actuating
member, a sensing surface or a sensing unit, by means of touch, proximity, turn, optical,
acoustic, thermal or any other influence.
This standard also applies to general purpose electronic switches with included automatic
functions where the operation and/or the control is initiated by a change of a physical
quantity, for example light, temperature, humidity, time, wind velocity, presence of persons,
etc.
This standard also applies to boxes for electronic switches, with the exception of mounting
boxes for flush-type electronic switches.
This standard also applies to electronic RCS and electronic TDS with a rated voltage not
exceeding 440 V and a rated current not exceeding 25 A, intended for household and similar
fixed electrical installations, either indoors or outdoors.
