Switches for appliances – Part 2-1: Particular requirements for cord switches
|Publication Date:||1 November 2010|
|ICS Code (Switches):||29.120.40|
This clause of Part 1 is applicable except as follows:
This International Standard 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.
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 may 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 standard.
This standard 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 switches may be combined with mechanical switches giving full disconnection or microdisconnection.
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 may be necessary.
NOTE 4 Attention is drawn to the fact that the standards for appliances may contain additional or alternative requirements for switches.
NOTE 5 Throughout this standard, the word "appliance" means "appliance or equipment".
This standard applies to switches intended to be connected to a flexible cable."
NOTE In this document, the word "cable" means "cable or cord".
This subclause applies.
This subclause does not apply.
