Abstract
An electrical charging system is provided, and includes a voltage supply and a conductive coupling element. The conductive coupling element includes a pilot circuit, a resistance element, a light-emitting diode (“LED”), and a switching element. The pilot circuit has a primary control contact and a ground contact. The pilot circuit is configured to be in communication with and receive voltage from the voltage supply. The pilot circuit is configured for supplying a control pilot voltage. The resistance element is electrically connected to the ground contact. The resistance element includes a resistance value. The LED is electrically connected to the resistance element and the ground contact, and has a forward voltage drop. The switching element is actuated to selectively connect the resistance element and the LED element to the primary control contact.
