Abstract:
A circuit comprising:a power source having a first terminal and a second terminal; a first modular load element having a first node and a second node; a final modular load element having a first node and a second node; a first connector including, a first terminal in communication with the first terminal of the power source and with the first node of the first modular load element, and a second terminal in communication with the second node of the first modular load element; a second connector including, a first terminal in communication with the first node of the first modular load element and with the first node of the final modular load element, and a second terminal in communication with the second node of the first modular load element and with the second node of the final modular load element; and a third connector including, a first terminal in communication with the first node of the final modular load element, and a second terminal in communication with the second node of the final modular load element and with the second node of the power source, wherein failure to establish electrical connection between the power source and at least one of the first and final modular load elements prevents operation of either of the first and final modular load elements.
