Editing Topre Realforce (section)

===General construction===
The Realforce keyboard design has remained largely unchanged since it was first introduced, and in fact some elements of the Realforce keyboard remain almost the same as Topre keyboards made as far back as 1987. The case is made of [[ABS]] plastic and, in the tenkeyless and full size models, is held shut without the assistance of screws. The Realforce numpads do have screws along the top edge holding the enclosure shut. 

There are two height-adjustable feet on top edge of the keyboard, and rubber feet on the front edge. On some models, there are four rubber feet arranged in such a way so that if the height-adjustable feet are deployed, two feet will still be in contact with the desk surface. The main internal components consist of the PCB, metal mounting plate (sometimes painted), [[Topre switches]], and connector cable (with [https://en.wikipedia.org/wiki/Ferrite_bead ferrite bead] inside the case). The cable is fixed internally via a removal 4-pin connector, generally in the top-right corner with the ground wire attached to the mounting plate. 

Internal routing channels run the cable to the centre of the keyboard where it can then be routed externally to the left or right of the keyboard as desired. On some models (mostly tenkeyless variants) there are [[DIP switch|DIP switches]] for controlling various functions which can include switching the left Ctrl and Caps Lock keys, enabling/disabling an embedded numeric keypad, enabling/disabling the Windows key and enabling/disabling the Firmware update mode. Some full sized models also have DIP switches which can only be accessed by opening the case. LED indicators for Num Lock, Caps Lock and Scroll Lock are present in the top-right corner of full sized keyboards, and on the keycaps themselves on many of the tenkeyless models.
