23、anical or 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

24、 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, betw

25、een the actuating 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

26、 unit is provided 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

27、 electronic 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 r

28、equirements 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.

34、d 3.3.103. NOTE 2 If a switch has a base which cannot be separated from the cover or cover plate, and requires an intermediate plate which can be removed for redecorating the wall, it is considered to be of design A, provided the intermediate plate meets the requirements specified for covers and cov

35、er plates. 7.1.102 According to outlet facilities: 7.1.102.1 switch with inlet/outlet facilities for rigid cables; 7.1.102.2 switch with inlet facilities for rigid cables and outlet facilities for flexible cables.

39、shock This clause of part 1 is applicable except as follows: 9.1 Add the following sentence to a): The switch shall be fitted with the conductor of the smallest or largest nominal cross-sectional area according to Table 4 whichever is more unfavourable, or with a rigid conduit, a pliable conduit or

40、a flexible conduit. EN 61058-2-4:2005 8 Addition to b): This test finger, with an electrical indicator, is not applied to membranes in inlet openings and is applied to thin-walled knock-outs with a force of only 10 N. Additional subclause: 9.101 Switches operated by means of a removable key or by me

41、ans of an intermediate part, such as a cord, a chain or a rod, shall be so designed that the key or intermediate part can only touch parts which are insulated from live parts. The key or intermediate part shall be insulated from metal parts of the mechanism, unless the clearances and creepage distan

42、ces between live parts and metal parts of the mechanism have at least the values specified in 20.1.4 and 20.2.4. Compliance is checked by inspection, by the test of 15.3 and, if necessary, by measurement. NOTE Lacquer or enamel is not considered to be insulating material for the purpose of this clau

44、itional note: NOTE Switches with a rated current of 10 A and less shall have terminals accepting conductors having a cross-sectional area of 1,5 mm2. 11.1.1.2.2 Addition to a): When testing with rigid conductors the tests are carried out first with rigid stranded conductors and the tests are then re

45、peated with rigid solid conductors if a solid conductor with the same cross-sectional area is specified in IEC 60227-3. Additional subclauses: 11.1.2.101 Terminals classified in 7.2.4 are in general not permitted. Such terminals may however in particular cases be permitted for the load side of the s

46、witch (see 11.1.3). EN 61058-2-4:2005 9 11.1.3.101 The power supply cable shall be connected only by a method of attachment such that the cable can be replaced without the aid of special purpose tools or by a cable not requiring special preparation. Connection from the switch to the appliance shall

47、normally be performed in a similar way, but may in particular cases (e.g. a particular manufactured connection between the switch and the appliance) be made by a method of attachment such that the cable can only be replaced with the aid of special purpose tools normally available to the manufacturer

48、 or his agent. A method of attachment such that the cable cannot be replaced without destroying the integrity of the switch shall not be used. 12 Construction This clause of part 1 is not applicable. Replacement: 12.101 Insulating linings, barriers and the like, shall have adequate mechanical streng

49、th and shall be secured in a reliable manner. Compliance is checked by inspection after the tests of clause 18. 12.102 Switches shall be so constructed as to permit: easy introduction and connection of the conductors in the terminals; adequate space between the underside of the base and the surface on which the base is mounted or between the sides of the base and the enclosure (cover or box) so that, after installation of the switch, the insulation of the conductors
