前言:这是协调CSA集团和UL家电开关标准——第2-5部分:转换选择器的特殊要求。这是CSA C22的第一版。2编号61058-2-5，以及第一版UL 61058-2-5。本协调标准基于2018年11月发布的IEC出版物61058-2-5:第三版电器开关–第2-5部分:转换选择器的特殊要求。IEC 61058-2-5的版权归IEC所有。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。CSA集团已将其作为加拿大国家标准发布。 范围:IEC 61058的本部分适用于手、脚或其他人类活动驱动的电器的转换选择器（机械或电子），操作或控制家用或类似用途的电器和其他设备，其额定电压不超过480 V，额定电流不超过63 a。这些转换选择器可由人、通过驱动件或通过驱动传感装置进行操作。执行元件或传感单元可以与开关集成，或者从物理上或电气上与开关分开布置，并且可以涉及执行元件或传感单元与开关之间的信号传输，例如电、光、声或热。 包含开关功能控制的附加控制功能的切换选择器在本文件范围内。本文件还涵盖了当执行元件或传感单元的操作由遥控器或装置或设备（如门）的一部分提供时，开关的间接驱动。注1:电子转换选择器可与机械转换选择器组合，实现完全断开或微断开。注2:电源电路中没有机械开关的电子转换选择器仅提供电子断开。 因此，负载侧的电路始终被认为是带电的。注3:对于热带气候中使用的转换选择器，可适用其他要求。注4:值得注意的是，电器标准可能包含对转换选择器的附加或替代要求。注5:在本文件中，“设备”一词是指“设备或设备”。本文档适用于拟并入设备中、设备上或设备中的转换选择器。本文件也适用于包含电子设备的转换选择器。

Preface:This is the harmonized CSA Group and UL standard forSwitches for Appliances – Part 2-5: Particular Requirements for Change-Over Selectors. It is the first edition of CSA C22.2 No. 61058-2-5, and the first edition of UL 61058-2-5.This harmonized standard is based on IEC Publication 61058-2-5: third editionSwitches for Appliances – Part 2-5: Particular Requirements for Change-Over Selectors, issued November 2018. IEC 61058-2-5 is copyrighted by the IEC.This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope:This Part of IEC 61058 applies to change-over selectors (mechanical or electronic) for appliances 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 change-over selectors 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 can involve transmission of a signal, for example electrical, optical, acoustic or thermal, between the actuating member or sensing unit and the switch.Change-over selectors which incorporate additional control functions governed by the switch function are within the scope of this document.This document 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 1 Electronic change-over selectors can be combined with mechanical change-over selectors giving full disconnection or micro-disconnection.NOTE 2 Electronic change-over selectors 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 3 For change-over selectors used in tropical climates, additional requirements can apply.NOTE 4 Attention is drawn to the fact that the standards for appliances can contain additional or alternative requirements for changeover selectors.NOTE 5 Throughout this document, the word "appliance" means "appliance or equipment".This document applies to change-over selectors intended to be incorporated in, on, or with an appliance.This document also applies to change-over selectors incorporating electronic devices.
