We have been serving a U.S.-based Bluetooth speaker manufacturer known for producing speakers that perform reliably in very harsh environments. As a result, their requirements for waterproof switches are exceptionally demanding—their testing standard involves submersion in water for 72 hours.

To meet this challenge, we implemented a copper-based FPC circuit combined with a waterproof gasket design and premium waterproof materials. This solution passed the rigorous waterproof testing with perfect score. We have been supplying this customer consistently for over five years.

If you have other specific requirements, please email us at sales@elecflex.com for details.
