ITT ETL18 switch teardown

u/Chyrosran22 introduces the vintage ITT ETL18 switch with horizontal flappy coil spring.
Published April 16, 2022

Thomas, describing himself as a "sucker for interesting and unusual switch designs", covers ITT ETL18, another obscure switch model from the early '80s.

Today we look at another, rather weird switch design - ETL18 switches from ITT. Superficially similar to Mitsumi Miniature mechanical in that it uses a horizontally-slung coil spring to provide tactility, it approaches this tactic in the opposite manner – Chyrosran22
