Telefon z guziczkami [TOWARY MODNE 47]

How did a non-tone telephone with a keypad work? What were the star and pound buttons used for? What is a reed switch? A continuation of the history of analog telephones based on the "Tulipan" device. The device shown at the end of the video, which allows you to connect a pulse-operated telephone to modern switchboards, was sent by my colleague Piotr. It's called the RETROFON, and if you search for it in your browser, you'll surely find its description. This item comes from a fan of the channel, to whom I sincerely thank you :) I invite you to support my channel: https://patronite.pl/smialekadam and to subscribe: https://www.youtube.com/AdamSmialek/?...
