Otis Cathode Touch Button – More Than You Ever Wanted To Know

Otis Cathode Touch Button – More Than You Ever Wanted To Know

January 30th, 2012

One of the coolest buttons, perhaps developed before it’s time was the Otis “Touch” button which was motionless. This button was very common back in the 1960’s and up into the 1970’s and 80’s. Contrary to how most assume the button worked it was not heat sensitive. It actually worked on the principle of sensing a voltage change that occurred inside a glass tube. A finger touching the face of the button created this drop which then activated the the tube directly behind the button. Again, pretty darn cool and a product ahead of it’s time.
