These Simple Circuit modules can be used to construct simple circuits of the type normally implemented on, for example a Worcester Circuit Board. Very useful for younger pupils to learn more applications of circuits anddevices. The modules are having 4mm plug connections. A current through the coil produces magnetism to cause the reed toswitch another circuit. The reed contacts are protected from shortcircuit damaged by low value series resistor.
