Hand Ringing Generator

A Hand Ringing Generator is a device that is used in telephone and telegraph equipment. It is part of the supply class Telephone And Telegraph Equipment, which falls under the supply group Communication, Detection, And Coherent Radiation Equipment.

The Hand Ringing Generator is responsible for generating the ringing signal in telephones. When a call is received, the Hand Ringing Generator produces an alternating current that creates the ringing sound in the telephone. This allows the user to be alerted to an incoming call.

Hand Ringing Generators are typically hand-cranked devices, meaning that the user manually turns a crank to generate the ringing signal. This eliminates the need for external power sources and makes the device portable and easy to use.

In summary, Hand Ringing Generators are important components of telephone and telegraph equipment, as they generate the ringing signal that alerts users to incoming calls.
