Значение и использование

Vibration encountered in the field is usually random in nature and this test can be used to determine the effects of random excitation on the membrane switch.

Random vibration can cause mechanical fatigue and failure by switch components either loosening or otherwise changing over time.

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.

Область применения

1.1 This test method establishes procedures for determining the effect of random 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.
