Abstract: An LED driver circuit that includes first and second switching mechanisms. The first mechanism is in a first switching condition when a source voltage is at or below a first threshold and moves to a second switching condition when the source exceeds the first threshold. The second mechanism is in a third switching condition when the source voltage is applied thereto and is at or below a second threshold less than the first threshold and moves to a fourth switching condition when the source voltage is applied thereto and is between the first and second thresholds. The third and fourth switching conditions each cause a safe current to flow through the LED. The second switching condition causes a safe current, preferably none, to flow through the LED, and the first switching condition causes the source voltage to be applied to the second mechanism. Also, a switching assembly including the circuit.
