A rotary dial telephone works by using a rotary dial to send electrical signals corresponding to the numbers dialed. When a number is selected on the dial, it creates a series of interruptions in the electrical current that are translated into the corresponding number by the telephone exchange. This information is then used to connect the call to the desired number. The rotary dial mechanism is connected to a series of contacts that open and close as the dial is rotated, allowing the electrical signals to be sent. **
