Technical What part is this (2 pictures)?

[borislavdj]

I have found this part in my car and I don't know what is it. I bought my car recently and when I cleaned under drivers seat it was there, disconnected. It is some kind of a taster (not switch), it has 4 pins at the black end.
Everything seems to work, maybe it is a spare part or one that is replaced. I don't have a clue... Here are 2 pictures attached.

Anyone?

That's a brake light switch. I'd check out your brake lights are functioning properly as that switch looks new and must have been bought for a reason. Intermittent operation of the lights is a common Stilo failure Have a look in the STILO GUIDES up above

Wow, this was fast!

Thank you. My brake lights are working fine. It seems like this one is dead or spare. Gonna check.

Check them by reflections so you can see what's happening as a common failing is only working maybe 9 out of 10 times. The one time you really wanted them is when a truck lands in your boot

Scary! You :devil: ....

I am thinking of running out of my office and check it right now on the parking space!
