Internal key-in-ignition-warning/ignition switch

A key-in-ignition warning switch integrally attached to a rotatable in a housing ignition switch, said warning switch positioned concentric with the rotational axis of the ignition switch, wherein said warning switch rotates with the ignition switch, comprises:

• an outer plunger having a cap end, a shaft midsection, and a first shaft flange attached to the end opposite said outer plunger cap end, wherein said first shaft flange includes a first electrical contact surface, and wherein said outer plunger includes a bore extending through said outer plunger shaft midsection;
• an inner plunger which comprises a cap end, a shaft midsection, and a second shaft flange attached to the end opposite said inner plunger cap end, wherein said second shaft flange includes a second electrical contact surface, and wherein said inner plunger extends through said bore;
• a plunger spring positioned between the shaft side of said inner plunger cap end and the outside surface of said outer plunger cap end, and wherein said plunger spring is concentric with said inner plunger;
• a housing spring positioned between the shaft side of said outer plunger cap end and the housing, and wherein said housing spring is concentric with said plungers;
• and
• a mechanical linkage between the key cylinder and said warning switch comprising a center shaft linearly slidable for engaging said warning switch in response to the insertion of the ignition key into the key cylinder, and an outer shaft rotatable with the key cylinder and coupled to said ignition switch.
