5、cy Committee (ECL/-). It is identical with IEC 1020-2-1:1991, (QC 960101), “Electromechanical switches for use in electronic equipment Part 2: Sectional specification for rotary switches Section 1: Blank detail specification” published by the International Electrotechnical Commission (IEC) and is a
6、harmonized specification in the IECQ System of quality assessment for electronic components. IEC 1020-2-1 was prepared by IEC Sub-Committee 48C: “Switches” of Technical Committee No. 48: “Electromechanical components for electronic equipment” and the United Kingdom participation in the drafting was
7、provided by Sub-Committee ECL/21/3 “Switches for electronic equipment” of Technical Committee ECL/21 “Electromechanical components for electronic equipment”. Scope. This standard lists the ratings, characteristics and inspection requirements which shall be included as mandatory requirements in accor
8、dance with BS QC 960100 in any detail specifications for these components. The British Standard which implements the IECQ Rules of Procedure is BS 9000 “General requirements for a system for electronic components of assessed quality” Part 3:1991 “Specification for the national implementation of the
9、IECQ system”. 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. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-references Internatio

The complete requirements for the switches described herein shall correspond to this detail specification and the current issues of IEC 1020-1 and IEC 1020-2. In the preparation of detail specifications, the conten
15、t of 1.5 of IEC 1020-2 shall be taken into account. Pages 2 through 6 provide the framework for a detail specification which is completed by inserting the necessary information. The numbers between brackets on the first page correspond to the following information which shall be inserted in the posi

Values shall be stated in 1.2 for the following characteristics when the following conditions exist (mandatory if applicable): low air pressure when an altitude rating is declared; logic level endurance when
17、 a logic level rating is declared; low level endurance when a low level rating is declared; end stops when end stops are declared; type of panel seal when a panel seal is declared; robustness of actuator; robustness of terminations; solderability when the terminals are declared to be solderable; res
18、istance to soldering heat when the terminals are declared to be solderable.
