We switched over to push button phones in the early 1970’s, they were already around in certain places by the mid to late 1960’s.
A lot of those early push button phones had rotary dial mechanisms and did not use the current DTMF signaling
I live in the same ranch house my dad built when I was 8 in 1968. He installed 2 touch tone phones circa 1984, one in the family room & one in my bedroom.
There are still 3 working rotary phones, one in the kitchen on the wall, one in the master bedroom & one in the basement.
My primary phone is a new touch tone one in the family room.
*****Since I only go out to grocery shop or for medical appts, I have managed to get by WITHOUT any cell or other mobile phone so far. Occasionally, a family member provides required text capability to receive activation codes, etc.
