What is the brake light switch and how does it work?

The brake light switch is a mechanical switch activated when you press the brake pedal. The switch has a plunger in it that contacts a lever in the brake pedal assembly. As that plunger is depressed when you push on the brake pedal, the contacts in the brake light switch closed and voltage flows to the brake lights — turning them on. The brake light switch is also in the circuit that controls the cruise control disengagement and the shift interlock safety feature installed on all newer cars. Failure of the brake light switch occurs due to wear on the internal electrical contacts in the switch, poor switch terminal connections, maladjustment of the switch, or damage to the brake pedal assembly.

When to consider replacing the brake light switch?

No brake lights. If depressing the brake pedal does not cause any of the brake lights to illuminate, the continuity of the switch will be tested. If only one brake light is out, then the issue is not the switch but rather the bulb, bulb socket or brake light circuit integrity.
Unable to shift out of park. The brake light switch is also wired into the shift interlock mechanism. If you are unable to shift out of park, with your foot on the brake, check to see if the brake lights will illuminate as you push the pedal. If they do not illuminate, failure of the brake light switch may be the cause of the no shift.
Intermittent operation of the brake lights or late operation. The brake light switch has to be in the proper position, and work consistently if the brake lights are to come on the instant you press the brake pedal. The switch can sometimes require adjustment, or the contacts may degrade, causing inconsistent operation of the switch.

How do mechanics replace the brake light switch?

The switch is first tested using a multimeter, including the terminal contacts to the switch, to determine if it is faulty. If the switch is functioning, the entire circuit must be tested to determine the cause of no brake lights.
Should the switch be judged defective, the switch is unthreaded from the mounting boss near the brake pedal assembly.
The new switch is threaded in and locked with an appropriate locknut once the new switch is properly adjusted.
The operation of the switch is tested to ensure instant illumination of the brake lights upon pressing the brake pedal.

Is it safe to drive with a brake light switch problem?

No. Should the brake light switch have failed, it is unsafe to drive the vehicle because drivers behind you will have no indication that you are slowing, intend to slow, or are stopped. Always address a failure of this type promptly to ensure your safety while driving.

When replacing the brake light switch keep in mind:

The mechanic will test the brake light switch directly to ensure that the issue is not elsewhere in the brake light circuit.
Occasionally, the issue is a maladjusted switch or a loose contact, and the mechanic can resolve the problem without switch replacement.

Ok, this is a little long but I'd love to hear your guys thoughts. I bought a 2014 Impreza AWD 135k miles with the automatic CVT transmission two days ago to flip ($1000) worth (~$7500). The guy got the car from a dealer auction, said it needed a transmission, and didn't want to put the time into it. I'm a car flipper hobbyist so I was looking for something to occupy my time. The car starts and the engine is great, no lights on the dash. The underlying problem is when I shift the car into a gear, THE CAR DOES NOT MOVE. It shifts fine, but the second I rev the engine to try to move the wheels, the dashboard lights up like everyone else here. Turn it off and on again, it goes back to being fine. OBD Scanner says p0700, p2750, and p2746. 1st code is a general transmission problem code, the other two are the primary and secondary speed sensors on the transmission. My initial plan was to get a trans from a junkyard ($450 used) ((car-parts.com) and throw it in, thinking that might cover all of my bases. So I started to drain the fluid to find out it looks dark brown or nearly black. (Youtube shows this might be common) I understand ALOT of people fix this with a valve body ($350-$450 used) or brake light switch (my lights all work and it shifts into gear fine) but after reading this, I might get lucky switching the speed sensors (2x $88). I refilled the transmission with CVT Fluid from the dealership ($75) so I can do an official diagnostic with a multimeter to check harnesses and the TCM (everything checks out). Unfortunately I need to at least lower the transmission a bit so I can take off the primary speed sensor, but if this doesn't work I'll get a transmission from a junkyard and swap it. Either way idk If I can lose on this flip. I'm hoping someone might respond by tomorrow to let me know if both speed sensors being bad would stop my car from moving.The next step in the diagnosis is to replace the speed sensors, but the codes were p0700, p2750, and p2746. I feel like it's weird for both sensors to go bad at the same time. But if they did, would this prevent my car from moving while in gear?
