Description
The keycaps are low-profile, and the keys are reduced travel. The force curve is sharp and smooth with positive action — the feel is a significant improvement over the previous models with the protruding space bars.
The membrane sheets are joined together using a heat stamp. The membranes are backed by a thin, flexible sheet of metal.
The PCB is labelled "DELL Totoro" with "P/N: 654000011590"; the upper case has Totoro spelt as "TOTOR/U" but typically the spelling "Totoro" is found, on both the mouldings and the membranes. The PCB manufacturer is Xinhua Electronics (Huizhou) Co., Ltd. (per the UL File Number of E241103). The membranes are marked "Lumirror" and "E107536", the latter giving Shinkong Synthetic Fibers Corp as the manufacturer.
Anecdotal evidence suggests that the keycap printing has lower durability than average, being the only modern Dell keyboard that seems to be prone to legend abrasion.
