This clause of part us replaced by the following:
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 the operation of lamp circuits and the control of the
brightness of lamps (dimmers) as well as the control of the speed of motors (e. g. those used
in ventilating fans) and for other purposes (e.g. heating installations), with a working voltage
not exceeding 250 V a.c. and a rated current up to and including 16 A.
The operation and control as mentioned above are performed intentionally 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.
NOTES.
1. This standard is not intended to cover devices falling within the scope of IEC 60730.
Examples of designs of electronic switches and functions are shown in Annex AA.
2. Electronic switches without a mechanical switch in the main circuit do not provide a “full of-state”.
Therefore, the circuit on the load side should be considered to be live.
