How JN White™ Helped

We designed and developed an extremely durable membrane switch that met all of the customer’s requirements. The switch included etched copperflex technology for a tail that can bend and crease. Additionally, the switch included 7 embedded LED’s, as well as highly specific components, such as metal domes and force actuators, for enhanced tactile feedback. Finally, the switch also included a 3M VHB gasket that is fully submersible (tested at 4 feet) and tailored to fit the specified sealing requirements.
