8、led Copy, (c) BSI BS QC 960100:1992 ii BSI 08-1999 National foreword This British Standard has been prepared under the direction of the Electronic Components Standards Policy Committee. It is identical with IEC 1020-2:1991 (QC 960100) Electromechanical switches for use in electronic equipment Part 2
9、: Sectional specification for rotary switches, published by the International Electrotechnical Commission (IEC), and is a harmonized specification in the IECQ system of quality assessment for electronic components. IEC 1020-2 was prepared by IEC Subcommittee 48C, Switches, of IEC Technical Committee
10、 No. 48, Electromechanical components for electronic equipment, and the United Kingdom participation in the drafting was provided by Subcommittee ECL/21/3, Switches for electronic equipment, of Technical Committee ECL/21, Electromechanical components for electronic equipment. The British Standard wh
11、ich implements the IECQ Rules of Procedure is BS 9000-3:1991 General requirements for a system for electronic components of assessed quality Part 3: Specification for the national implementation of the IECQ System. The Technical Committee has reviewed the provisions of IEC 390 and IEC 512-7, to whic
12、h normative reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Complian

Rotary switches covered b
18、y this part of IEC 1020 have a rated voltage not exceeding 300 V and a rated current not exceeding 5 A (d.c. or r.m.s. values). It does not apply to rotary-actuated in-line switches. The object of this part of IEC 1020 is to: a) prescribe preferred ratings and characteristics; b) select the appropri
19、ate quality assessment procedures and test methods from IEC 1020-1; c) prescribe the general performance requirements for rotary switches. 1.2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IEC 1020. At the
20、 time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of IEC 1020 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
