A key-in-ignition warning switch (10) is integrally mounted within an ignition switch (11). The warning switch (10), positioned along the rotational axis (17) of the ignition switch (10), comprises an inner plunger (15), an outer plunger (16), a plunger spring (28), and a housing spring (31). As the ignition key (26) is inserted into the key cylinder (12), a linkage (14) between the key cylinder (12) and the warning switch (10) pushes against the inner plunger (15), which in turn pushes against the outer plunger (16). As the key (26) is inserted completely into the key cylinder (12), contacts (24,25) attached to the plungers (15,16) make contact with terminals (34,36) located within a terminal block (35) attached to the ignition switch (11). When both plunger contacts (24,25) and mating terminals (34,36) are in contact, the key-in-ignition warning circuit is completed, thereby enabling the associated warning devices.
