Most cars have a solenoid that blocks the lever from moving from park unless the brake lights are on.
If the brake switch is faulty it will not come out of park.
i think that the light switch is shorting out are the auto light switch shorting for the thumb switch
If your question is what I think it is than the answer is yes. There is a switch that turns your brake lights on, it is also the same switch that releases the gearshift that will allow you to remove the vehicle from park. You should be able to hear a little click when you depress the brake pedel. If you don't hear that click and your brake lights are not coming on and you cant get it out of park than I would definitely take a look at that switch, It is usually located right on the pedel mechanism itself.
Check fuse for brake switch, check switch, or light control module,
The brake light switch is mounted right at the brake pedal - a pin coming out of the switch actually touches the pedal.Can a bad switch keep a car from going into reverse: no. It CAN keep a vehicle from shifting out of park thoughSee "Related Questions" below for more

Who says it has a kill switch? I have workshop manual and did not see one! Have had trouble with auto shifter stick in park..had to short out "kill " switch, to prevent starting when not in park.
You either got a bad new Switch or more likely you have a power supply problem to the park side of the switch.
Possibly the brake light switch is bad. I had a recall on a Ford Taurus that spoke of this problem. The brake light switch releases a solenoid that holds the shifter in park.
It only allows starting the engine in park or neutral. It also is the reverse light switch.
APPLY BRAKES AND SEE IF BRAKE LIGHTS COME ON. IF NO BRAKE LIGHTS, REPLACE THE BRAKE LIGHT SWITCH LOCATED ON THE BRAKE PEDAL ARM AND THIS SHOULD ALLOW YOU TO SHIFT OUT OF PARK. IF THAT BRAKE LIGHT SWITCH IS BROKE, YOU WON'T BE ABLE TO GET IT OUT OF PARK
You might have a bad brake light switch. If you don't have brake lights the switch is bad. When your brake light switch isn't working it wont send a signal to the shift solenoid.
