Switches for appliances - Part 1: General requirements (IEC 61058-1:2016)
This part of IEC 61058 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 61058 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 61058 applies to circuitry when evaluated with a switch and necessary for the
switching function.
This part of IEC 61058 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 61058 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 61058 does not contain requirements for safety isolating switches
(IEC 60050-811:1991, 811-29-17).
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 61058, the word "appliance" means "appliance or equipment".

Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) les exigences relatives aux constructions d'interrupteurs mécaniques sont maintenant incluses dans l'IEC 61058-1-1;
b) les exigences relatives aux constructions d'interrupteurs électroniques sont maintenant incluses dans l'IEC 61058-1-2.
Stikala za aparate - 1. del: Splošne zahteve (IEC 61058-1:2016)
Ta del standarda IEC 61058 se uporablja za stikala za aparate. Stikala so namenjena upravljanju električnih aparatov in druge opreme za gospodinjstvo ali podobne namene z nazivno napetostjo, ki ne presega 480 V, ter z nazivnim tokom, ki ne presega 63 A.
Stikala za aparate upravlja
– oseba prek sprožilnega elementa,
– posredno proženje,
– sprožilna enota za zaznavanje dotika.
Prenos signala med sprožilnim elementom ali enoto za zaznavanje in stikalom se lahko izvaja prek optične, akustične, toplotne, električne ali druge ustrezne povezave in lahko zajema enote za daljinsko upravljanje.
Ta del standarda IEC 61058 se uporablja za stikala za aparate z dodatnimi nadzornimi funkcijami, ki jih upravlja stikalo, povezano z elektronskimi vezji in napravami, ki so potrebne za namensko in/ali pravilno delovanje stikala.
Ta del standarda IEC 61058 se uporablja za vezje, kadar se to vrednoti s stikalom in je potrebno za funkcijo preklapljanja.
Ta del standarda IEC 61058 se uporablja za stikala za aparate v povezavi z naslednjimi deli:
1-1. del: Zahteve za mehanska stikala, in/ali
1-2. del: Zahteve za elektronska stikala.
Ta del standarda IEC 61058 se ne uporablja za naprave, ki jih zajemata standarda:
– IEC 60669 (vsi deli), Stikala za gospodinjske in podobne fiksne električne napeljave, in
– IEC 60730 (vsi deli), Avtomatske električne krmilne naprave.
Ta del standarda IEC 61058 ne vsebuje zahtev za varnostne ločilnike (IEC 60050-811:1991, 811-29-17).
OPOMBA 1: Za stikala, uporabljena v tropskih podnebjih, so lahko potrebne dodatne zahteve. OPOMBA 2: Upoštevajte, da lahko standardi za končni izdelek aparatov vsebujejo dodatne ali drugačne zahteve za stikala.
OPOMBA 3: V celotnem tem delu standarda IEC 61058 beseda »aparat« pomeni »aparat ali opremo«.
