Through the control of the time control switch on and off
Their assembly of 3-way control switch difficult, if you just want to use rather than engage in research, you can directly buy multi-channel controller, Taobao sale, there are two-way six-way optional, each way alone Set one or more start and stop times. You can Taobao search 'multi-channel time controller' to understand the selection.
? If you do not understand the electronic technology, just want time to control a switch, and now there are finished microcomputer timer switch can choose a lot of features and practical, Taobao search to find out about.
IGBT is the abbreviation of the insulated gate bipolar transistor, its control is not a simple problem. If you are an electronic enthusiast, you can learn about the principle and drive method, and then learn the time base circuit or microcomputer timing drive circuit, then you can consider the assembly of the timing of the IGBT switch circuit.
