At one time, rotary dials were used in phones to be able to select the number you wanted to call.
Using the rotary dial, the number needing to be called could be entered by successively putting one's finger into the dial and rotating of clockwise as far as it would go and then letting the dial return under its own power.
These rotary dial phones are seldom seen these days and today's modern landline telephone exchanges are being updated to more modern technologies and the rotary dial phones are often not compatible with the new systems.
However these rotary dial phones are a part of our heritage - they were used for many years and provided a reliable way of selecting or "dialling" the required number.
Today a push-button approach is used on land line and mobile phones, but rotary dial phones still have an attraction as they are part of vintage technology. Even mobile phones use a screen keypad or touchscreen where the numbers are touched.
