The rotary dial phone used a wheel to dial a sequence of numbers. It went into use as early as the 1890s to overcome the need for an operator to connect all calls.

The rotary dial remained in use until the 1980s and beyond.. Even today, many telephone exchanges still support the rotary dial signalling.
