*The "S"in the part number denotes top tape seal versions. To order without top tape seal, leave
the "S" off the part number when ordering.
**Style "GB" contains 30µ gold plated terminals.
* To order, add L as a final suffix to the part number. For example, 76RSB08 becomes 76RSB08L; and 90B08S becomes 90B08SL.

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.
*For the most current soldering & cleaning processing
guidelines, reference Grayhill Dip Switch Processing
Information, Bulletin 1234
Materials and Finishes
Vibration Resistance:
per Method 204, Test
Condition B, 1 mS opening (10 mS allowed)
Mechanical Shock:
per Method 213, Test
Condition A. 1 mS opening (10 mS allowed)
Thermal Shock Resistance:
per specification;
