JN White® was contacted by a Department of Defense (DoD) Tier 2 Supplier when they needed assistance engineering a DoD membrane switch with custom tricolor LEDs that would drive an 8” x 12” touchscreen. JN White® expertly produced a custom membrane switch with three custom LED colors, which is now utilized by the military.
The customer needed tricolor LEDs, in color combinations that are not available in market as a single component. The customer’s “pin out” request posed another challenge in that a single membrane switch was not useable. Multiple tails were needed to ensure that they corresponded to the placement of the connectors on the PCB of the end device.
In order to visualize the design of the membrane switch for the customer, JN White® utilized 3D modeling to present each engineering phase. This type of modeling provided life-like accounts of the membrane switch. To fulfill the customer’s unique color request, JN White® placed two LEDs on an upper circuit and a third LED on the lower circuit. Since the correct tail placement was imperative in order for the circuitry to work properly, JN White® considered the number of required tails and tail placement thoroughly while constructing the overall design. After expertly engineering for both of the company’s requests, JN White® added diffusing film to avoid LED hot spots. This extra step ensured that color would not show through in undesired areas.
In order to produce the perfect product for the customer, JN White® created custom tooling specifically for this particular membrane switch. In addition to producing an expertly crafted membrane switch, JN White® exceeded the company’s timeline expectations.
Through utilization of JN White®’s engineering and production expertise, as well as close cooperation between the two companies, the customer received a custom membrane switch tailored to their exact specifications.
Its carefully crafted engineering and skillful production enables the membrane switch to be used in the military.

Lisa L., Medical Device
"JN White has been exceptional in working with our company in order to develop the look and feel of our new MRI patient worn transmitter. We had originally worked with a prior manufacturer for an earlier version of this product with much less desirable results. JN White delivered a clean professional product at a very reasonable price on time!"
