SELF-DIAGNOSTIC SWITCH

摘要

A self-diagnostic acoustic wave touch actuated switch assembly includes a substrate having an acoustic wave cavity, a transducer operatively connected to the acoustic wave cavity, a processing unit, and at least one light emitting member operatively connected to the processing unit. The transducer is configured to generate a trapped acoustic wave within the acoustic wave cavity. The processing unit is operatively connected to one or both of the acoustic wave cavity and/or the transducer. The processing unit may be configured to activate the at least one light emitting member when the processing unit detects one or both of a switch malfunction and/or a potential switch malfunction.
