Circuit has a high degree of confidentiality remote stable and reliable performance from employees and static low power consumption, to achieve multi-channel switches and other controls remote cheap price, stable and reliable,and the space is small, beautiful appearance, there are four buttons. Through this design enables students to fully consolidate the basic theoretical knowledge and application of digital and analog circuits, and power electronic control devices designed to be simple to use and solve real-life problems.Students can think independently to solve problems and analyze problems.According to the issues raised, to explore different design. Find information by electronic technology to enable students to understand the trends in the development of enlightened thinking, broaden their horizons.
