Editing Metal contact switch (section)

==Overview==
Metal contact switches are simple [[Keystroke sensing#conductive|conductive]] arrangements where electrical current is momentarily switched on during keystrokes, or held on when a latching switch is toggled.

Simple in principle, there are in fact many designs of contact arrangement, from simple to elaborate.

Metal contact switches are chiefly found in discrete modules, although arrangements exist such as the [[Hi-Tek High Profile]] and [[MEI Sabrecoil]] switch grids that place all the switches into a unified frame that is manufactured and shipped to the customer as a single unit.
