Editing ITW magnetic valve (section)

==History==
ITW filed a patent for their magnetic valve switch in 1974. The tooling was later sold to [[Devlin]]; these Devlin-made switches are reported to have been very popular in the newspaper editing industry, with most European and North American newspapers specifying them across their operations.<ref name="priv-1" /> Devlin ended production of them in 2005, choosing to use only [[Cherry MX]] switches.

Devlin referred to these switches as "Cortron" switches. No further details are known, as all documentation was disposed of (along with the tooling) at the termination of production.
