It was derived by CENELEC from IEC Publication 1058-2-1 (1992) first edition and Amendment 1:1995, published by the International Electrotechnical Commission (IEC). The CENELEC common modifications have been implemented at the appropriate places in the text. The start and finish of each common modification is indicated in the text by tags . Where a common modification has been introduced by amendment, the tags carry the number of the amendment. For example, the common modifications introduced by CENELEC amendment A11 are indicated by . The start and finish of text introduced or altered by amendment is indicated in the text by tags !“. Tags indicating changes to IEC text carry the number of the IEC amendment. For example, text altered by IEC amendment 1 is indicated by !“. The foreword of EN 61058-2-1 makes reference to the “date of withdrawal”, dow, of the relevant national standard. In this case the relevant national standard is BS 3955 which will cease to be applicable to cord switches within the scope of BS EN 61058-2-1 on 1 July 1995. Certification and marks will not be awarded after this date with respect to BS 3955. However, such certification and marks already awarded may continue to apply to production until 1 July 2000. BS 3955 will be progressively amended to delete specific switches at the date of withdrawal agreed. The foreword of the EN amendment 1 to EN 61058-2-1 makes reference to the “date of withdrawal (dow) of conflicting standards” as “1996-09-01”. In this case the relevant standard is BS EN 61058-2-1:1993 but the date of withdrawal relates only to those parts of the British Standard amended by Amendment 1. Certificates and marks will not be awarded after this date with respect to the British Standard not incorporating Amendment 1. They will be awarded with respect only to the amended British Standard. However, such certificates and marks, already awarded with respect to the unamended British Standard may continue to apply to production until 2001-09-01. This British Standard is to be read in conjunction with BS EN 61058-1:1992 General requirements, which it supplements or modifies. The many references to Part 1 should be read as references to BS EN 61058-1, which is the English language version of EN 61058-1 which was derived from the 1992 print of IEC publication 1058-1, first edition. Product approval Attention is drawn to the fact that products conforming to this British Standard may be approved by the British Electrotechnical Approvals Board for purposes of participation in the CENELEC Certification Agreement and in the CB Scheme of the IECEE. (Details of the BEAB Approval Scheme are given on the inside back cover.) This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

These switches are intended to be operated by a person, 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 acuating 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 provided by a remote control or a part of an appliance or equipment such as a door. NOTE 1Electronic switches may be combined with mechanical switches giving full disconnection or micro-disconnection. NOTE 2Electronic switches without a mechanical switch in the supply circuit provide only electronic disconnection. Therefore, the circuit on the load side is always considered to be live. NOTE 3For switches used in tropical climates, additional requirements may be necessary. NOTE 4Attention is drawn to the fact that the standards for appliances may contain additional or alternative requirements for switches. NOTE 5Throughout this standard, the word “appliance” means “appliance or equipment”. 1.2 Replacement: 1.2 !This standard applies to switches intended to be connected to a flexible cable.“ 1.3 Text deleted 1.4 This subclause does not apply. 2 Normative references This clause of Part 1 is applicable except as follows: 2.1 Addition: 227: Polyvinyl chloride insulated cables of related voltages up to and including 450/750 V. 245: Rubber insulated cables of rated voltages up to and including 450/750 V. 598-1:(1986), Luminaires Part 1: General requirements and tests. 3 Definitions This clause of Part 1 is applicable except as follows: 3.3 Definitions relating to the different types of switches Additional definition: 3.3.101 cord switch: separately enclosed switch intended to be connected to a supply and/or to an appliance or equipment by means of flexible cable(s) NOTEThe flexible cable(s) may enter the switch enclosure in any direction and may be in line with the enclosure.
