Time relays are divided into two types: on-time delay type and off-time delay type, and their symbols are shown in the following figure. For the power-on delay type time relay, when the coil is powered on, the power-on delay type contact acts after the delay time (the normally closed contact is opened and the normally open contact is closed), and the contact immediately returns to normal after the coil is powered off; For the power-off delay type time relay, when the coil is powered on, the power-off delay type contact acts immediately (the normally closed contact is opened and the normally open contact is closed). After the coil is powered off, the contact will not return to normal until the delay time is passed.

Soon I saw Li Jianzhong's C # Object-Oriented Design Pattern Lecture on MSDN's Webcast. A very good series of lectures gave me a new understanding of design patterns. I realized that learning design patterns, specifically learning object-oriented design patterns, should start with learning object-oriented. "The principle of object-oriented is like understanding the rules of chess, and the design pattern is equivalent to a mess. I don't know what the rules look at." Since I have been doing ASP.NET development for the previous year, although I have been writing classes, learning Duwamish to make hierarchical architecture, typed DataSet and custom entity classes, it seems that I haven't used interfaces much in the past year, and I seldom use any polymorphism. In fact, the understanding of object-oriented programming is still very vague.
