Self-diagnostic switch
First Claim
1. A self-diagnostic acoustic wave touch actuated switch assembly comprising:
- a substrate having an acoustic wave cavity;
a transducer operatively connected to said acoustic wave cavity, said transducer configured to generate a trapped acoustic wave within said acoustic wave cavity;
a processing unit operatively connected to one or both of said acoustic wave cavity and/or said transducer; and
at least one light emitting member operatively connected to said processing unit.

Abstract
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.
