Preface 

This is the harmonized CSA Group and UL standard for Switches for Appliances - Part 2-1: Particular Requirements for Cord Switches . It is the first edition of CSA C22.2 No. 61058-2-1, and the first edition of UL 61058-2-1. This harmonized standard is based on IEC Publication 61058-2-1: third edition, Switches for Appliances - Part 2-1: Particular Requirements for Cord Switches, issued June 2018. IEC 61058-2-1 is copyrighted by the IEC. This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the International Harmonization Committee on Switches for Appliances are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. This standard was reviewed by the CSA Integrated Committee on Wiring Devices, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. 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 

Clause 1 of IEC 61058-1:2016 is applicable except as follows: Addition: This document applies to cord switches (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 250 V and a rated current not exceeding 16 A. 

Throughout this document, the word "appliance" means "appliance or equipment". 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 or arranged separately from the switch. The transmission of a signal between the actuating member or sensing unit and the switch can be made either physically or electrically (for example, electrical, optical, acoustic or thermal). Switches 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 such as a door. 

NOTE 1 Electronic switches can 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 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 can apply. 

NOTE 4 Attention is drawn to the fact that the standards for appliances can contain additional or alternative requirements for switches. 1DV D2 Modification: Add the following to Clause 1 of the Part 2: This part of CSA C22.2 No. 61058/UL 61058 does not apply to cord dimmer switches.
