AS NZS 61058.1 pdf download.Switches for appliances
1 Scope
This part of IEC 61 058 applies to switches for appliances. The switches are intended to 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. Switches for appliances are intended to be operated by – a person via an actuating member, – indirect actuation, – an actuating sensing unit. Transmission of a signal between the actuating member or sensing unit and the switch may be connected by optical, acoustic, thermal, electrical or other relevant connection and may include remote controlled units. This part of IEC 61 058 applies to switches for appliances provided with additional control functions governed by the switch provided with electronic circuits and devices that are necessary for the intended and/or correct operation of the switch. This part of IEC 61 058 applies to circuitry when evaluated with a switch and necessary for the switching function. This part of IEC 61 058 applies in general to switches for appliances in conjunction with the following parts: – Part 1-1: Requirements for mechanical switches, and/or – Part 1-2: Requirements for electronic switches. This part of IEC 61 058 does not apply to devices covered by: – IEC 60669 (all parts), Switches for household and similar fixed-electrical installations, and – IEC 60730 (all parts), Automatic electrical controls. This part of IEC 61 058 does not contain requirements for safety isolating switches (IEC 60050-81 1 :1 991 , 81 1 -29-1 7). NOTE 1 For switches used in tropical climates, additional requirements may be necessary. NOTE 2 Attention is drawn to the fact that the end product standards for appliances may contain additional or alternative requirements for switches. NOTE 3 Throughout this part of IEC 61 058, the word “appliance” means “appliance or equipment”.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 General terms and definitions 3.1 .1 mechanical switching device switching device designed to close and open one or more electric circuits by means of separable contacts Note 1 to entry: In the IEC 61 058 series the terms “switching devices” and “switches” are used interchangeably. [SOURCE: IEC 60050-441 :1 984, 441 -1 4-02] 3.1 .2 conductive part part which is capable of conducting current although it may not necessarily be used for carrying service current [SOURCE: IEC 60050-441 : 1 984, 441 -1 1 -09] 3.1 .3 live part conductor or conductive part intended to be energized in normal operation, including a neutral conductor, but by convention not a PEN/PEM/PEL conductor Note 1 to entry: For appliance switches, “live part” implies a risk of electric shock. Note 2 to entry: Unless otherwise specified, parts connected to a SELV supply or equal to or less than 24 V are not considered to be live parts. 3.1 .4 pole of a switch portion of a switching device associated exclusively with one electrically separated conducting path of its main circuit and excluding those portions which provide a means for mounting and operating all poles together Note 1 to entry: A switch is called “single pole” if it has only one pole. If it has more than one pole, it may be called “multipole” (two-pole, three-pole, etc.) provided that the poles are coupled in such a manner as to operate together. [SOURCE: IEC 60050-441 :1 984, 441 -1 5-01 , modified — Pole of a switching device replaced by pole of a switch] 3.1 .5 detachable part part which is removable without the use of a tool when the switch is mounted as in normal use 3.1 .6 tool screwdriver, coin, or any other object which may be used to operate a nut, a screw or a similar part 3.1 .7 normal use use of the switch for the purpose for which it was made and declared 3.1 .8 unique type reference UT identification marking on a switch such that by quoting it in full to the switch manufacturer a unique switch model can be identified Note 1 to entry: This note applies to the French language only. 3.1 .9 common type reference CT identification marking on a switch which does not require any further specific information additional to that provided by the marking requirements of this part of IEC 61 058 for selection, installation and use in accordance with this part of IEC 61 058 Note 1 to entry: This note applies to the French language only. 3.1 .1 0 cover cover plate protective cover cover made of insulating material, used to cover live parts in order to avoid accidental electric contact and which is accessible when the switch is mounted as in normal use but which can be removed with the aid of a tool
