The text of lEC Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards.
Attention is particularly drawn to the following: In this adopted standard, reference appears to certain International Standards for which Indian Standards also exist.
The corresponding Indian Standards which are to be substituted in their respective places are listed below along with their degree of equivalence for the editions Indicated: International Standard lEC 61058–1 and magnetic devices lEC Rotating machinery lEC Electrical installations of buildings tEC Tests — Test T: Tests — Test Eh: Cartridge, fuse- links tF.

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 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.
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 rull 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 may, be necessary. Attention Is drawn to the Fact that the standards for appliances may contain additional or alternative requirements for switches.

Consequently, the thermal current will normally be lower than the rated current This necessitates additional tests of the terminals, contacts, etc. Such a conductor may be a supply lead or interconnecting cord between separate parts of an appliance or it may form part of the fixed wiring 3.
