SWITCHES FOR HOUSEHOLD AND SIMILAR FIXED ELECTRICAL INSTALLATIONS – Part 2-1: Particular requirements – Electronic switches (Edition 4.1; Consolidated Reprint)
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 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@ for example@ light@ 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. Electronic switches complying with this standard are suitable for use at ambient temperature not normally exceeding 25 ??but occasionally reaching 35 ??In locations where special conditions prevail@ such as in ships@ vehicles and the like and in hazardous locations@ for example@ where explosions are liable to occur@ special constructions may be required.NOTE 1 This standard is not intended to cover devices which are designed to be incorporated in appliances or are intended to be delivered together with a specific appliance and which are within the scope of IEC 60730 or IEC 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.
