This clause of Part 1 is applicable except as follows: 1.1 Replacement: 1.1 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”. 1.2 Replacement: 1.2 This standard applies to switches intended to be connected to a flexible cable." NOTE In this document, the word “cable” means “cable or cord”. 1.3 This subclause applies. 1.4 This subclause does not apply.

1.1 This International Standard 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 may 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 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 change-over selectors may 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 may be necessary. NOTE 4 Attention is drawn to the fact that the standards for appliances may contain additional or alternative requirements for change-over selectors. NOTE 5 Throughout this standard, the word "appliance" means "appliance or equipment". 1.2 This standard applies to change-over selectors intended to be incorporated in, on or with an appliance. 1.3 This standard also applies to change-over selectors incorporating electronic devices.

Applies to portable devices consisting of a plug, a residual current device (RCD) and one or more socket-outlets or a provision for connection. They do not incorporate overcurrent protection. They are intended for single-phase circuits for rated currents not exceeding 16 A for rated voltages not exceeding 250 V a.c., or for rated current not exceeding 32 A for rated voltages not exceeding 130 V a.c. to earth.

Dielectric withstand voltage testing is useful for design verification, quality control of materials, and workmanship. This test method is used to verify that the membrane switch can operate safely at its rated voltage, and withstand momentary overpotentials due to switching, surges and other similar electrical phenomena. Specific areas of testing are, but not limited to: Conductor/dielectric/conductor crossing point, Close proximity of conductors, and Any other conductive surface such as shielding or metal backing panel. Dielectric withstand voltage testing may be destructive and units that have been tested should be considered unreliable for future use. Testing using ac voltage may be useful for switches intended for control circuits powered by ac voltages.1.1 This test method covers the verification of a specified dielectric withstand voltage or dielectric breakdown voltage of a membrane switch.

This test procedure summarizes the various tests that are made on ac high-voltage indoor and outdoor circuit breakers, except for generator circuit breakers, which are covered in IEEE Std C37.013-1997. It describes accepted methods used in making the tests and specifies the tests that will verify assigned ratings under ANSI/IEEE standards. This procedure does not preclude the use of other equivalent or more effective methods of demonstrating ratings.
