3、and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or non-member of EIA from manufacturing or selling products not conforming to such Standards
4、 and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than EIA members, whether the standard is to be used either domestically or internationally. Recommended Standards and Publications are adopted by EIA without regard to whether o

By such action, EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Recommended Standard or Publication. This EIA Specification is considered to have i
6、nternational standardization implication, but the International Electrotechnical Commission activity has not progressed to the point where a valid comparison between the EIA standard and the IEC document can be made. This Specification does not purport to address all safety problems associated with
7、its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.

12、sal No. 2197, formulated under the cognizance of the EIA P-13.4 Subcommittee on In-Line and Miscellaneous Switches.) The complete requirements forthe switches describedherein shall consist of this Detail Specification, the latest issue of EIA-520E000, “Sectional Specification for In-Line Switches of
13、 Certified Quality,“ and the latest issue of EIA-5200000, “Generic Specification for Special-use Electromechanical switches of Certified Quality. It 1.0 SECTION ONE - SCOPE AND OBJECT 1.1 Scope The Dual In-line Machine Insertable Switches of certified quality covered by this Detail Specification: 1.
14、1.1 Have maximum enclosure dimensions of 32.5 mm (1.280 inch) long, 7.26 (0.286) wide and 4.57 (0.180) high. 1.1.2 Have a maximum rated voltage of 50 Vdc. 1.1.3 Have a maximum rated current of 100 mA. 1.1.4 Have slide actuators that are flush with, or recessed below, the top surface of the switch. 1
15、.1.5 Are sealed against the entrance of soldering flux and cleaning solutions during the process of assembly to circuit boards. 1.2 Object The object of this Detail Specification is to provide all information required for the identification, quality assessment, and certification of these switches. T
16、he information, contained herein or by reference, is complete and sufficient for inspection purposes, 2.1 The related documents, units, symbols, terminology and markings are prescribed in Section Two of Sectional Specification EIA 520E000, and General Speci- fication EIA 5200000, and the following a
17、dditional requirements: 2.5.1 Switches shall be marked so as to identify the state of the contacts with respect to the actuation position (e.g., “ON“ on appropriate side, a round dot on the closed contact side, etc.).

19、 information: 3.1.1 Qualification Inspection Tests: The qualification tests are prescribed in Table 1 herein for the qualification of the entire subfamily of switches covered by this Detail Specification. Qualification switches must have 8 poles. 3.4.5 Lot-By-Lot Inspection Tests: The lot-by-lot ins
20、pection tests ara prescribed in Table II herein. 3.4.6 Periodic Inspection Teats: The periodic inspection tests are prescribed in Table III herein. 4.0 SECTION FOUR - TEST METHODS AND REQUIREMENTS 4.1 General The test methods and requirements are prescribed in Section Four of Generic Specification E
21、IA 5200000, Section Four of Sectional specification EIA 520E000, and are supplemented by the following information: 4.1.6 Switches with tape top seals shall be supplied with contacts in the closed position and seals in place for Group A, the solderability test of Group B, and the machine soldering t
22、est of Group C of Qualification Test Table I. These seals may be removed for all other qualification tests. Insulation resistance and voltage proof measurement in Group A only will be made between adjacent poles (the closed circuit prevents taking these readings aeroas open contacta). EIA 520EAAB 89

24、n QualificationGroups B, D, E and Periodic Test Group B. Insulation Resistance Insulation resistance shall be measured at 100 +, 5 Vdc, and at stan- dard atmospheric conditions. Insulation resistance shall not be less than 1000 megohms. Voltage Proof Voltage proof measurements shall be made with an
25、applied voltage of 500 Vac (rms) . Maximum allowable leakage current is 500 microamperes. The switch shall withstand the test voltage without sustained arcing, breakdown, or damage to insulation. Vibration Vibration testing shall be in accordance with EIA 186-8 Type III. Strength of Terminations Str
26、ength of terminations shall be tested in accordance with EIA-186-6 with a 1.1 pound- load on a minimum of three randomly selected terminals on each specimen.

27、 and one-half of the specimens tested in accordance with Test 8-5 (low level load). The number of cycles shall be 2000, and no sticks or misses are allowed. Capacitance The maximum allowable capacitance shall be 5 picof arads. Machine Soldering The machine soldering test shall be run in accordance w
28、ith EIA-448-2 Method 16 and with Method A fluxing (touching body), a soldering time of no less than four seconds, and cleaning by immersion and spray.(all four solutions in each case). After the test, there shall be good solder connections, no externally visible indication of leakage, contact resist
29、ance shall be in accordance with 4.5.1, and insulation resistance shall be in accordance with 4.5.2, and all marking shall be readable. - EIA 520EAAB 89 3234b00 13073569 3 - EIA-52OEAAB Page 4 TABLE I: QUALIFICATION APPROVAL INSPECTION TESTS Test Method & Group Group A Visual Examination Dimensions
