The complete requirements for the switches described herein shall consist of th
3、is Detail Specification, the latest issue of EIA 520E000, “Sectional Specification for In-line Switches of Certified Quality,“ and the latest issue of EIA5200000, “Generic Specification for Special-use Electrochemical Switches of Certified Quality . 1.0 1.1 e 1.2 2.0 2.1 e SECTION ONE - SCOPE AND OB
4、JECT Scope The Dual In-line Machine Insertable Switches of certified quality covered by this Detail Specification: 1.1.1 Have maximum enclosure dimensions of 33.02 mm (1.300 inch) long, 10.16 (0.400) wide and 14.06 (0.554) high. 1.1.2 Have a maximum rated voltage of 50 Vdc. 1.1.3 Have a.maximum rate
5、d current of 100 mA. 1.1.4 Have slide actuators that are raised above, or recessed below, the top surface of the switch. 1.1.5 Are sealed against the entrance of soldering flux and cleaning solutions during the process of assembly to circuit boards. Object The object of this Detail Specification is
6、to provide all information required for the identification, quality assessment, and certification of these switches. The information, contained herein or by reference, is complete and sufficient for inspection purposes. SECTION TWO - GENERAL The related documents, units, symbols, terminology and mar
7、kings are prescribed in Section Two of Sectional Specification EIA 520E000, and General Speci- fication EIA 5200000, and the following additional 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
