1. Introduction:
The purpose of this report is to provide information along with test data with respect to a
change to be made in the plastic materials used in the construction of the Grayhill 90 Series
DIP low profile switches. The change if from the PPA resin that is currently used to a PA 4/6
GF30 resin (UL94 V-0 rated). This change is being made due to obsolescence of the current
material. The report details the extensive product testing that was performed to ensure that
customers of the 90 series product can be assured of continued use of the switches with no
negative impact to their current production processes and as components in their products.
The material change affects the high temperature plastic material that is used for the main
body of the switch (base assembly) and the cover that is ultrasonically welded to the base
assembly during the switch assembly process. All other switch materials and finishes will not
be changing from the current materials used at the time of this report. For the purpose of this
product testing, two five hundred piece orders of the 90B08ST were built in the same
production cell using the current and the proposed material to ensure that no differences could
be attributed to variation in equipment, assembly methods, or personnel. The switches were
then tested side by side to ensure that a control group was subjected to identical testing
throughout the process.
The test switches were divided into nine subgroups and tested as described under the
individual headings. All test switches were measured for Contact Resistance, Insulation
Resistance, and Dielectric Withstanding prior to any testing. The switches described in the
following pages are all from the five hundred sample of switches built using the new material.
If there were any differences noted in performance between the new material switches and the
control group that information is included under the respective subgroup heading.
2.0 Subgroup 1:

2.1. Thermal Shock- Fifty switches were tested for thermal shock as specified in MIL-
STD-202, Method 107G (test condition B1) that specifies 25 thermal cycles between –
65°C and +125 C.
2.2. Mechanical Life: After Thermal Shock, the fifty switches were tested for
mechanical life per MIL-STD-83504/12. The test conditions were for a minimum of
2,000 cycles at a rate not greater than 10 cycles per minute. The test load used was
10mA resistive with an open circuit voltage of 5 VDC.
2.3. Dielectric Withstanding Voltage- Following mechanical life testing, the fifty
switches were tested per MIL-202, Method 301 at a test voltage of 500 VAC RMS in
the open position. The requirement is that there shall be no arcing, flashover, or
breakdown of insulation or damage, and that leakage current shall be no greater than
100 microamperes.
2.4. Contact Resistance. - The switches were then measured for contact resistance per
MIL-STD-202, Method 307 using a test current of 10mA maximum at 1 VDC. The
contact resistance is not to exceed 100 milliohms on any switch position after
mechanical life as described in 2.2.
2.5 Operating Force-The actuation force of each switch was measured to ensure that
each switch position meets a 1.0-ounce minimum force after mechanical life.
All fifty switches in subgroup 1 met the criteria as specified above.
