This page show how the various
components are assembled to produce an Executive
keyboard

How it all
goes together.
This sequence of photographs show the
assembly steps in manufacturing an Executive keyboard.
Punched key-plate.
The stainless steel key-plate (shown
here without it's protective film) is the first
component in the assembly sequence.
112 Cherry MX key-modules.
112 Cherry MX key-modules are then
fitted (by hand) into the key-plate.
Key-plate with key-modules.
The protective film is left on until final
assembly to keep everything nice and shiny.

key-module wiring.
The key-modules are then wired up in
an XY matrix. Discrete wiring rather than a dedicated
PCB is used as this allows complete customisation of the
keyboard's switch arrangement.
Although labour intensive this wiring
method has been used by PCD Maltron since it's first
keyboards over twenty five years ago and has proven to
be very reliable.
Base with Perspex sides and feet, USB
controller and hardware.
The stainless
steel base has it's protective film removed and the
controller, cable and feet are fitted.
Perspex top.
The Perspex top has protective films
on both sides. The underside
white protective film is removed prior to final assembly.

testing.
The Perspex top retains it's
transparent protective film which will be removed by the
user.
