Series 6184<ref name="marquardt-c" /> is a low-profile keyboard switch series from Marquardt; series 6184 followed the fairly similar Series 6180. All known switches are linear.
Description[edit | edit source]
Standard (non-LED) switches are all equipped with a diode, which is only visible if the switch top is removed<ref name="gh-thread-internals"/>. Pictures of a disassembled switch can be seen here<ref name="gh-thread-internals"/> as well.
The keyfeel of the Marquardt white (Linear) switch is similar to that of a Cherry MX Black, though it feels a bit stiffer.
US patent 4653179A covers the manufacture of the contact module used in several Marquardt types including Series 6184.
