Double-key touching lamp switch circuit (3)
As shown in the figure, it is a double-key touching lamp switch with Darlington transistor, the feature of circuit is that touching tablet and 220V AC mains are isolated by power transformer T, it is relatively safer. The T can be 220V/9V, 5VA small power transformer; K should use ultra - small JZC-22F/2Z-09 power relay.
