*A top tape seal is required for switches that are machine
soldered or heavily cleaned after hand soldering. To order top
seal versions, add "S" to the Grayhill part number.

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.
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;
no failures; passes contact resistance.
Terminal Strength:
per specification
Thermal Aging:
1,000 hours at 85°C; no failures.
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.
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.
Non-Conductive Parts:
Thermoplastic
(UL94V-O)
Potting Material:
epoxy, 76,78 only.
Protective Cover:
76,78, only-polycarbonate.
Tape Seal:
76, 78: polyester film
90:
polyimide film
Tape Seal Integrity:
passes gross leak test
using 125°C flourinert for 20 seconds minimum.
Reference MIL-STD-202, Method 112.
