WELCOME
There are two thing I want to give you
#1 Recall, Ignition Switch, Short Circuit Defect info for 88-92 Fords On April 25, 1996 Ford Motor Company announced the recall of approximately nine million cars, trucks and minivans that may be equipped with a faulty ignition switch that may be responsible for causing hundreds of fires. In no case has any death or serious injury resulted from these fires. The recall covers 1988-93 models sold in both the U.S. and Canada that Ford says, "In a very small number of vehilces, the ignition switch could cause an internal short circuit, creating the potential for overheating, smoke and possibly fire in the steering column of the vehicle." The faulty ignitions switches can cause a short circuit that may lead to a fire whether the vehicle is turned on or off.

#2 the switch is not located at the key cylinder
it is near base of steering column as show is this diagram
The part that you insert the key in is called da Lock Cylinder
Lock Cylinder Replacement in a 94 (same for your 92...from Bronco, F-Super Duty Chassis Manual); "...To install ignition cylinder use steps 1-6 on the left column...)

Switch Adjustment in a 96 (same for your 92) from 1996 F-150, F-250, F-350 F-Super Duty and Bronco Workshop Manual; "...NOTE: A new replacement ignition switch (11572) assembly will be set in the RUN position as received. Adjust the ignition switch by sliding the carrier to the RUN position. Make sure the ignition switch lock cylinder (11582) is in the RUN position. The RUN position is achieved by rotating the ignition switch lock cylinder approximately 90 degrees from the LOCK position. Install the ignition switch into the column actuator hole. It may be necessary to move the ignition switch back and forth slightly to align the ignition switch mounting holes with the lock cylinder housing threaded holes. Install retaining screws. Tighten to 6-8 Nm (53-71 lb-in). Connect the electrical connector to the ignition switch. Tighten lock ***** to 0.8-1.3 Nm (7-11.5 lb-in). Connect battery ground cable (14301). Check ignition switch for proper function, including START and ACC positions. Also, make sure the column is in the LOCK position..."

Next is your Brake Light issue
Switch, Brake Light On/Off Light (Stoplight Switch) Description & Operation in 92-96; "...The electromechanical stoplight switch, installed on the pin of the brake pedal arm, straddles the push rod of the power brake booster (2005) but is not attached directly to the push rod.
The stoplight switch moves with the pedal arm when the brake pedal (2455) is depressed. The stoplight switch actuating pin is held by spring pressure against the rear end of the power brake booster. Because of the slight clearance between the eye of the push rod of the power brake booster and the brake pedal arm pin, the pin and the stoplight switch move forward slightly before the push rod moves when the brake pedal is depressed. This relative movement between the stoplight switch and the end of the push rod moves the actuating pin rearward in the stoplight switch, closing contacts on the stoplight switch completing the circuit to the rear lamps (13405).
When the brake pedal is released, the stoplight switch moves rearward in relation to the push rod. The spring in the stoplight switch returns the actuating pin to its normal position, opening contacts on stoplight switch and interrupting the circuit to the rear lamps..."

Check for power on both sides of the switch w/brake pedal in normal position
should have power just on fus3ed wire lt green/red and no voltage on lt green wire
wiring diagram by seijirou
or disconnect switch connector and test switch for continuity - should have none w/brake @ norm pos and continuity w/brake pedal depressed
If the switch is bad, try to adjust or replace
If sw is good;
