MIL-PRF-22885/9L
Qualification inspection: All applicants for qualification approval shall demonstrate that each of their
items conforms to all the requirements specified in the applicable documents, singularly and in
combination with all other previously qualified items, regardless of manufacturer.
When the basic sensitive switches are qualified to MIL-PRF-8805, switches shall be tested in
accordance with table III.
When the basic sensitive switches are not qualified to MIL-PRF-8805, the switch type for which
qualification is sought shall be submitted to the complete tests in accordance with table X of MIL-PRF-
22885.
Group A inspection: Tests may be performed on individual MIL-PRF-22885/11 units and indicator
modules prior to assembly as a MIL-PRF-22885/9 switch, when applicable. Contact resistance may be
performed on individual basic sensitive switches prior to assembly as a MIL-PRF-22885/11 unit.

1/ Solderability and resistance to soldering heat are not applicable.
2/ Sea level, dc resistive load only. Contact resistance after electrical endurance not applicable.
3/ When approval of seal M22885/13-02 is desired, the seal shall be properly assembled to the switch
during the tests. There shall be no more than 10 percent change in transmittance after completion of
the tests, nor shall there be any crazing or cracking.
4/ The plunger stop test shall be performed by removing the switch assembly and installing the stop.
5/ For approval of units with EMI screens, resistance between EMI screen and housing shall be tested
before and after electrical endurance.
6/ For approval of units without EMI screens, substitute M22885/9-04WWWW for M22885/9-
250WWWW.
