1.0 TEST REQUIREMENTS The Electro Switch Corporation electro switch is re-quired to pass the seismic' vibration test specified in paragraph 2.0 b.elow, without evidence of mechanical damage or deterioration.
2.0 TEST PROCEDURES The electro switch was secured to a test fixture by its normal mounting means and the test fixture was secure'ly bolted to the 45' biaxial moving table, with a biaxial seismic simulator, of the Acton Environmental Testing Corporation (AETC) seismic test facilities for seismic vibration testing in the first front-to-back biaxial direction.
Switch contacts were monitored for momentary openings and closures throughout the subsequent seismic vibration test with the AETC/ Matrix Cha tter Box calibrated for 10 micro-seconds.
The closed circuits of the switches have been wired in series and the open circuits have been wired in parallel for monitoring switch circuit change during test.
The 28 -VDC panel indicator lights of the switch. shall be energized with rated voltage and observed for failure during test.
Two monitoring accelerometers and one control accelero-
~
meter were placed on the test item / test fixture in the following locations:
ACCELEROMETER NO.

The following resonance survey was performed first in the first front-to-back biaxial direction:
0.5 to 35 liz, 0.28g's resultant, 1 octave / minute sweep Following completion of the resonance survey in the first front-to-back biaxial direction, the unit was rotated 180* to the second front-to-back biaxial direction, and the above specified resonance survey was performed.
Following completion of the resonance survey in the second f ront-to-back" biaxial direction, the unit was rotated 90* to the first side-to-side biaxial direction, and the above specified resonance survey was performed.
~
Following completion of the resonance survey in the first side-to-side biaxial direction, the unit was rotated 180' to the second side-to-side biaxial direction, and the above specified resonance survey was performed.
The AETC Seismic Simulator was then setup for biaxial seismic vibration with a random input.
The equivalent random vibration level of the Electro Switch Corporation Specification Required Response Spectrum was computed.
With the test item setup in the first front-to-back bi-axial direction, five 1/2 SSE, 30-second random vibration exposures were performed.
Test Response. Spectra at a Q of 20 were computed employ-ing a Spectral Dynamic SD331 Shock Spectrum Analyzer fast fourier transform program.
The spectra were compared to the Required Response Spectrum.
X-Y Plots of the TRS made with the SD331 are included with this report.
Af ter performing five 1/2 SSE random vibration inputs in the first front-to-back biaxial direction, the test item was rotated 180' and the test was repeated in the second front-to-back biaxial direction.
Again five 1/2 SSE 30-second random vibration exposures were performed.

F Following completion of the five 1/2 SSE in the second front-to-back biaxial direction, the test item was rotated 90* to the.first side-to-side biaxial direction and five 1/2 SSE 30 seconds random vibration exposures were performed.
Following completion of the five 1/2 SSE in the first side-to-side blaxial direction, the test item was ro-tated 180' to the second side-to-side biaxial direction and five 1/2 SSE 30-second random vibration exposures were perfo'rmed in the second side-to-side biaxial -
direction.
The test item / test fixture assembly was then rotated 90* to the first front-to-back biaxial direction and one full SSE 30-second random vibration exposure was perforced.
Following comple' tion of the one full SSE in the first front-to-back biaxial direction, the test item was rotated 180* to the second front-to-back axis and a full SSE 30 seconds random vibration exposure was performed.
The test item was then rotated 90* to the first side-to-side axis and a full SSE 30 seconds random vibration exposure was performed.
The test item was then rotated'180' to the second side-to-side axis and the full SSE 30 seconds random vibra-tion exposure was performed.
This completed the testing of the. electro switch.
During all the tests, outputs of all three accelero-meters were displayed on oscillographic recorders.

3.0 TEST RESULTS 4
No resonances of the electro switch were detected in the resonance survey in either the front-to-back biaxial direction or the side-to-side biaxial direction.
No damage or deterioration occurred to the Electro Switch equipment as a result of resonance survey.
There was no evidence of mechanical damage or deteriora-tion to the Electro Switch equipment as a result of the 1/2 SSE in any of the four biaxial directions.
No damage or deteri6' ration ' occurred to the Electro Switch equipment as a result' of the full SSE in any of the four biaxial directions.
No contact chatter occurred throughout the seismic vibra-tion testing.
