What is the Phone keypad

The touch-tone telephone was officially opened by the American Telephone and Telegraph Corporation in November 1963. The phone keypad is an improved version of the carousel phone.
The push-button telephone service was officially opened by the American Telephone and Telegraph Corporation in November 1963. Almost everyone who first touches a touch-tone phone thinks it is far better than a rotary phone. Researchers at Bell Labs have racked their brains to make this new product acceptable to people. They experimented with 16 key arrangements, crossover, disc, and so on. They also made a large number of articles on the size, shape, spacing of keys, elasticity, and even the shape of the parts that touch the tip of the finger.
Saving dialing time is just one of the original intentions of the button-type telephone. In fact, from the beginning, the technical expert has designed a new telephone to be designed as a remote data input device. It is from this design idea that the researchers added the "*" and "#" keys to the keyboard in 1968. Although some of the researchers' design ideas - such as the switch to control household appliances through telephones - have not been realized so far, but the push-button telephones have created a new era of voice data communication.
Modern telephones generally use a push-button structure. When making a call, press the corresponding number key, the phone automatically generates a corresponding set of DTMF codes that are perceived by the switch. When the dialing is completed, the switch can automatically transfer the call to the corresponding place according to the perceived number.
