The product is a vandal resistant, membrane switch user interface control panel with full ESD protection, flexible etched circuit design, pocket assembly and insertable legendability. The product has a steel black plate and standoffs
for use in a high current application.
The client required that the panel have an all-lights-on condition while in operation. This requirement exceeded the current load capacity of normal screen printing technology. The existing supply base only serviced the screen
printed silver circuit technology.
MNR Technology reviewed the design and created a “pocket” assembly. In this assembly, an etched flex circuit was utilized to support the switch and LED functions. This reduced the flex circuit footprint to the required area only, which resulted in lower cost. We utilized a steel back plate with stand-offs to provide frontal attack resistance, and assembly to support the LCD touch panel. Everything was integrated through the copper etched circuit tails to the mother board.
The client received a completed panel assembly that met all electrical, functional and vandal resistant requirements as specified.
