Διακόπτες για οικιακές και παρόμοιες σταθερές ηλεκτρικές εγκαταστάσεις - Μέρος 2: Ειδικές απαιτήσεις - Τμήμα 1: Ηλεκτρονικοί διακόπτες

This clause of part 1 is 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 controls), 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 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 electronic switches where the operation or control is made by physical means, e.g. light, wind velocity, presence of persons, etc. NOTE 1 - This standard is not intended to cover devices falling within the scope of EN 60730 or EN 61058-1. Examples of designs of electronic switches and functions are shown in annex AA. NOTE 2 - Electronic switches without a mechanical switch in the main circuit do not provide a full off-state. Therefore, the circuit on the load side should be considered to be live.
