Abstract: A connector for controlling the operation of a vehicle engine is disclosed, the connector including a male connector element having first and second contacts fixedly retained therein and a female connector element having first and second resilient terminals fixedly retained therein. The first and second terminals of the female element are each provided with an arcuate end portion disposed so that the arcuate end portions of the terminals normally contact one another. When the male element is inserted into the female element, the arcuate end portions of the terminals in the female element are separated from one another and make contact with the first and second contacts of the male element. This contact permits the vehicle engine to be controlled by the switch. On the other hand, if the connector elements are uncoupled, the arcuate end portions of the female connector element are in contact with one another so as to complete and close a circuit defined by wires coupled to the terminals of the female element.
