The JF-TGK01 series microcomputer time control switch is a highly integrated electronic switch device used for power switch program control. It can set one output to control 8 different time switches (or two outputs can simultaneously turn on or off the power, or alternately turn on or off the power, with a total of 16 different on/off control programs), and can set on/off control programs within one week. This machine has a memory function, which can maintain the time display and the original set product of various control programs for more than 6 months even when disconnected from the mains power supply. It can control various electrical devices that require time control, such as street lamps, billboards, light boxes, radio and television equipment, garden irrigation equipment, lighting in breeding farms and yards, lighting in tourist attractions, household appliances, etc. It is a safe and reliable electronic switch that is controlled by weak electricity, and is new and intelligent. For example, when used in conjunction with AC contactors, it can control three-phase high-power electrical equipment.
