Environmental Ratings Meets all requirements of MIL- S-83504.** Where Grayhill performance is superior, the MIL spec is listed in parentheses. Moisture Resistance: Per MIL-STD-202, Method 106. Soldering Information Series 90 MIDIP and Series 76 recessed rocker (76RSB style) sealed switches have been tested to EIA Standard RS-448-2. Similar performance can be expected from other sealed Series 76 and 78 DIP switches. Solderability: Per MIL-STD-202, Method 208 Resistance to Soldering Heat: 76RSB: Passes EIA Standard using two, four, and six second soldering time. 90: Per MIL-S-83504, six second test. Fluxing: Per EIA RS-448-2 with flux touching switch body. Cleaning: 76, 78 and 90 series tape sealed products: Passes immersion test using water/ detergent. Acceptable solutions include 1-1-1 trichlorethane, freon, (TF, TE, or TMS), isopropyl alcohol, detergent (140°F maximum). Terpene acceptable for Series 90 only. Solutions which are not recommended include acetone, methylene chloride, freon TMC. DIP Switches 76 Mechanical Life: Operations per switch position Materials and Finishes Shorting Member (Ball): Brass, gold-plated over nickel barrier. Base Contacts: Copper alloy, gold-plated over nickel barrier. Terminals: Copper alloy, matte tin plated over nickel barrier.
