19、ndently mounted switches FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-operation on all questions conc

20、erning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this

21、preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the tw

22、o organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced h

23、ave the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake

24、to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure t

25、o indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held respon

26、sible for identifying any or all such patent rights. This part of International Standard IEC 61058 has been prepared by subcommittee 23J: Switches for appliances, of IEC technical committee 23: Electrical accessories. This standard shall be used in conjunction with IEC 61058-1, Switches for applianc

27、es Part 1: General requirements (third edition, 2000). It lists the changes necessary to convert that standard into the IEC standard: Particular requirements for independently mounted switches. This part constitutes the first edition of IEC 61058-2-4. This consolidated version of IEC 61058-2-4 is ba

28、sed on the first edition (1995) documents 23J/132/FDIS and 23J/143/RVD and its amendment 1 (2003) documents 23J/253/FDIS and 23J/255/RVD. It bears the edition number 1.1. A vertical line in the margin shows where the base publication has been modified by amendment 1. The annex R forms an integral pa

29、rt of this standard. The annexes S and T are for information only. 61058-2-4 IEC:1995+A1:2003 9 The committee has decided that the contents of the base publication and its amendment 1 will remain unchanged until 2007. At this date, the publication will be reconfirmed; withdrawn; replaced by a revise

30、d edition, or amended. In this part: a) The following print types are used: requirements proper: in roman type; test specifications: in italic type; explanatory matter: in smaller roman type. b) Subclauses, figures or tables which are additional to those in part 1 are numbered starting from 101. 610

31、58-2-4 IEC:1995+A1:2003 11 SWITCHES FOR APPLIANCES Part 2-4: Particular requirements for independently mounted switches 1 Scope This clause of part 1 is applicable except as follows: 1.1 Replacement: This International Standard applies to independently mounted switches for appliances (mechanical or

32、electronic) actuated by hand, by foot or by other human activity, to operate or control electrical appliances and other equipment for household or similar purposes with a rated voltage not exceeding 480 V and a rated current not exceeding 63 A. These switches are intended to be operated by a person,

33、 via an actuating member or by actuating a sensing unit. The actuating member or sensing unit can be integral with or arranged separately, either physically or electrically, from the switch and may involve transmission of a signal, for example electrical, optical, acoustic or thermal, between the ac

34、tuating member or sensing unit and the switch. Switches which incorporate additional control functions governed by the switch function are within the scope of this standard. This standard also covers the indirect actuation of the switch when the operation of the actuating member or sensing unit is p

35、rovided by a remote control or a part of an appliance or equipment such as a door. NOTE 1 Electronic switches may be combined with mechanical switches giving full disconnection or micro-disconnection. NOTE 2 Electronic switches without a mechanical switch in the supply circuit provide only electroni

36、c disconnection. Therefore, the circuit on the load side is always considered to be live. NOTE 3 For switches used in tropical climates, additional requirements may be necessary. NOTE 4 Attention is drawn to the fact that the standards for appliances may contain additional or alternative requirement

37、s for switches. NOTE 5 Throughout this standard, the word “appliance” means “appliance or equipment”. 1.2 This subclause of Part 1 is not applicable 1.3 This subclause of Part 1 is applicable. 1.4 This subclause of Part 1 is not applicable. 61058-2-4 IEC:1995+A1:2003 13 2 Normative references This c

38、lause of part 1 is applicable except as follows: Addition: IEC 60227-3:1997, Polyvinyl chloride insulated cables of rated voltages up to and including 450/750 V Part 3: Non-sheathed cables for fixed wiring 3 Definitions This clause of part 1 is applicable, except as follows: Additional definitions:
