<p>To allow a keyboard to be assembled from key switches, the housings (1) of these switches are made of elastic plastic material and are provided on their side faces with rounded pegs (5) and recesses (7). Since the recesses (7) are slightly narrower than the diameter of the pegs (5), the housings (1) are detachably clamped when fitted together, so that a keyboard assembled in this manner can be once again dismantled into individual switches.</p> |
