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 (e.g. those used in ventilating fans) and for other purposes (e.g. heating controls), with a rated voltage not exceeding 250 V and a rated current not exceeding 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.
