Scope

1.1 This test method establishes procedures for determining the effect of sinusoidal vibration, within the specified frequency range, on switch contacts, mounting hardware, adhered component parts, solder or heat stakes, tactile devices, and cable or ribbon interconnects associated with a membrane switch or membrane switch assembly.

Significance and Use

Vibration encountered in the field is not usually simple harmonic.

This test can be used to determine relative motion between parts, critical frequencies, adhesion strengths, loosening of parts or other physical effects that can cause fatigue or failure.

Experience has shown that this test will expose potential failures associated with the electronic components of a membrane switch, where tests of lower levels will not.

This practice can be used to qualify a membrane switch for aerospace, medical and other applications.

This test is potentially destructive, intended for device qualification.

Either Test Condition A or B can be chosen, based upon the intent of the test determined by the qualified engineer.
