NATIONAL FOREWORD

This Indian Standard which is identical with IEC 1020-5/IEC QC 960400 (1991) ‘Electromechanical switches for use in electronic equipment-Part 5 : Sectional specification for push button switches’ issued by the International Electrotechnical Commission (IEC), was adopted by the Bureau of Indian Standards on the recommendation of Electromechanical Components and Mechanical Structures for Electronic Equipment Sectional Committee (LTD 7) and approval of the Electronics and Telecommunication Division Council.

The text of the IEC standard has been approved as suitable for publication as Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
