One of the multiple sets of colorful light chain circuits that flashes in cycles

It consists of thyristor and reed switch. The rotation of the disk with two permanent magnets controls the closing of the reed switch
, thereby controlling the conduction and closing of the thyristors Vl-V4. Changing the number and position of the magnets on the disk can cause
the lighting conditions of the lantern chain to change accordingly. The reed switches KRi-KR4 use JAG5-22; the lanterns H1~H4 can use 220V, and
the total power of each group is 40W bulbs (parallel connection).
