Works like it should!
Easy to install. Looks like OEM. Fit was perfect. Seems like good quality after 30 days.

Direct fit
Direct fit esay installation well made working great... however ford needs to get their head out of their "ya know" and make the ground wire longer on the wiring harness .. what's the point of having a harness whip if the ground wire is 6 inches long? Anyway if I need one I'll buy again

Quality part
Was able to fix a 2016 Ford Fusion which had its brake lights on at all time even when the car was off, swapped this and the issue was gone. Very easy fix, and hasn't gone bad yet.

Internet and Amazon saved us hundreds of dollars!
Getting this part from Amazon was a great idea! Mechanic wanted $800+ dollars to fix our 2016 Ford Fusion. We decided to research online and watched videos to determine that the problem was this part. Found it here for $10 and it was delivered the next day. Installed the new one and the car is running great, saving us a lot of money!!!

Replaced OEM and works great so far with no issues.
Found our Fusion brake lights were stuck on and wouldn't go off. Turns out the switch went bad. This replaced the original and has worked great so far with no issues.

Brake switch
This fit and was identical to the factory part. But when I installed it, I turned it, and it fell apart. I ended up purchasing the one from Ford, and there is a clear difference in quality. I'm sure this would have worked, but the plastic is definitely not as tough as the factory switch. Been in the automotive repair field for 26 years. Took a chance to save some money but I knew better.
