This Telephone Switch . Normally known as Telephone Switch.Assembling your own custom keyboard is quickly becoming a fun hobby among computer enthusiasts, but what if you could build a 6-foot-long one? This tactile Big Switch from NovelKeys looks like a normal mechanical Cherry MX switch, but the major difference is that it is four times the size! Each of these switches is 100 percent fully functional and can be used to build your very own giant keyboard or numeric 10-key pad, an emergency eject button for your favorite space flight simulator, or a giant “nope-outta-there” button for times when you see a scary picture on the internet and need to backpedal as quickly as possible. Really, whatever you can do with a regular-sized keyboard switch can be done with a NovelKey!..Originally, all telephone calls required the participation of an operator. This began to change when a crude automatic switch, invented by Almon Strowger, was improved into the first practical automatic switch around 1900. The application of Strowger switches, as well as panel, rotary, and crossbar switches, automated the telephone system. Automatic telephone switching was critical in making the telephone the influential mass market technology it became. It was also influential as an early and widespread example of automation of an electromechanical service.
