The Specialists in "Sound" Management
Quality — that is what Sigtronics was founded on over 49 years ago. Sigtronics pioneered the voice activated intercom market in 1974 and continues this commitment to produce high quality communication products for aviation. All design, assembly, and quality control is done at our facility in San Dimas, California. This allows us to maintain our high standards and fast customer response.
