20、take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark
21、, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This European Standard was prepared by CECC WG 24, “Switches and sensors”. The text of the draft based on document CECC 96500 Issue 1:1992 was submitted t
22、o the formal vote for conversion to a European Standard; together with the voting report, circulated as document CECC (Secretariat) 3329. It was approved by CECC as EN 196500 on 30 April 1993. The following dates were fixed: This specification has been formally approved by the CECC and has been prep
23、ared for those countries taking part in the System who wish to issue national harmonized specifications for MEMBRANE SWITCHES. It should be read in conjunction with the current regulations for the CECC System. At the date of printing of this specification, the member countries of the CECC are Austri
24、a, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

It contains detailed instructions for the preparation of detail specifications and describes the capabi
42、lity approval procedures for membrane switches and panels. This sectional specification includes the blank detail specification CECC 96501. 1.1.2 General instructions Detail specifications (DS) for membrane switches shall be prepared by completing the following pro-forma as indicated by the guide li
43、nes given below and in accordance with CECC 96000. The layout given shall be adhered to as closely as is practicable. Each DS shall relate to only one type of membrane switch as defined in 2.2.3a) of CECC 96000 and to one assessment level but may if found convenient, cover more than one style of tha
44、t type and/or number of variants within each style. For membrane switches, “style” and “variant” have meanings as defined below. The style of a membrane switch of a given type is determined by the following parameters: current and voltage ratings; type of substrate; climatic category. Switches for w
45、hich it is wished to claim structural similarity shall be of the same type and style, in accordance with 3.2 of CECC 96000. The variants within a style of membrane switch are determined, for example, by the following parameters: method of mounting; no. and position of individual switches; graphics c
46、olour, size, type face etc.; overall size; sealing; surface texture; operating force; terminations; illumination; no. of, and position and size of windows or holes for mounting other components; tactile or non-tactile response. The DS shall contain all the necessary information to identify the parti
47、cular type, style(s) and variant(s) of membrane switch which it covers. This information shall include at least the following: a) Ratings and characteristics: 1) Ratings and characteristics shall be taken from the preferred list given in 2.3 of CECC 96000 unless more severe values are to be prescrib
48、ed; 2) Proof voltage shall be determined as stated in 4.3.4.1 of CECC 96000. b) Detailed dimensions including mounting method; c) Mechanical operating characteristics; d) Terminations; e) Sealed or non-sealed; f) Indication and/or illumination; g) Assessment level. 1.1.3 Terminology The terminology
49、used in preparing the DS shall be in accordance with 2.2 of CECC 96000. Any further special terms which are found necessary shall be defined in the DS.
