Origin of rotary DlP switch style

A rotary DlP switch, as its name implies, is a function that encodes rotations by converting mechanical displacements into electrical signals during rotation, which are then examined and processed by sensors to output pulses or code signals.

One type of switch that can be used for encoding is called a rotary DlP switch, which utilizes the basic principles of optics, magnetic attraction, induction and capacitance in its operation. Through the use of this series of principles to complete and cooperate with the work, the formation of a kind of rotary digital signals transmitted while working in a coherent manner.

In the early 50's, Europe and the United States appeared one after another is simple is the code switch, through the induction as well as the electrical signal propagation method. Because of the simple structure, the calculation degree is the most advanced level in the past, and because of the simple design, the use of the mission is relatively long. The most representative machine was the early computer. Because the calculation accuracy was the highest priority, it was emphasized in foreign countries, and after later improvement, not only the accuracy was more accurate, but also the speed was greatly improved, especially the size was incomparable with the previous one. Due to the change of size, it was widely used, and gradually formed the present and small rotary DlP switch.
