- rmason 4y agoCourtesy of a ham radio newsletter here in Michigan. By 1896, eight years after Strowger patented his switch the Automatic Telephone Exchange Company introduced the rotary dial. Interestingly it took quite a bit of time for the rotary dial to become dominant even though it was much easier to use. The rotary dial, something that I never had to learn totally baffles today's teenagers. https://www.youtube.com/watch?v=oHNEzndgiFI https://www.youtube.com/watch?v=oHNEzndgiFI
