Plate is arranged on the both ends of the radiator bottom.
Skilled person will appreciate that the control drive part of the fling-cut switch can use independent current source, effectively reduce outer
The driving power of portion's signal, and improve signal interference function.The fling-cut switch can coordinate the pcb board that ARM7 chips are embedded in, can be with
Antijamming capability is improved, detects silicon controlled module running temperature in real time, the run time of intelligent control switch and driving fan
Start, the shut-in time, improve operational efficiency and energy-conservation.
Beneficial effect：The utility model discloses a kind of low-voltage intelligent dynamic fast-switching switch structure, the structure includes
Plastic casing, primary connection terminal, secondary wiring terminals, radiator, electric fan, can be with thorough using the fling-cut switch of the structure setting
Bottom solves the problems, such as installation and maintenance inconvenience, further improves efficiency of assembling, saves substantial amounts of human resources.The fling-cut switch can
Extension external interface is RS485 interfaces, improves the intelligent level of switch.
