Foxboro P0400QB


The external appearance of the Foxboro P0400QB Is industrial in nature. This includes an "ACK" button located on the left of the keyboard for I/A actions.  Additionally, there are 2 full-sized RJ45 Jacks on the back of the keyboard for interfacing with the respective computer. 


This keyboard was OEMed for Foxboro:



The keycaps are made out of PBT with dye-sublimated legends. The keycaps for the fifth generation include clips on the sides of the keycaps to secure them properly to the switch.

The keycaps on generation five boards contain wire stabs similar.

Upper Case

The upper case is made out of a single piece of beige ABS plastic. The plastic is textured due to the molding process that is used to create the upper case.

Lower Case

The lower case is molded from the same ABS plastic as the upper case. A set of slots are located in the lower case that join the two halves together. 

Switch Plate

The switch plate is made out of stamped steel. The plate has deeper stamping around the switches so that the entire switch plate could be produced with less material. The plate is only coated with a clear coat.


The PCB is a double-sided PCB with all traces on the backside of the PCB. The keyboard has a separate motherboard to which the keyboard connects. The keyboard module still keeps its own controller and therefore could be used separately.
