Are unknown parts and speed fixing done?

Hello, there is a piece coming from above as shown in the picture. I started the vehicle and pressed nothing. I think this part could be and I am thinking of attaching a cruise control to my vehicle. 2005 model 206 HDI brake switch should have 4 sockets.

I know that there should be 4 cables, not sockets. If that switch is out of the brake pedal, start the vehicle, press the switch button, see if the brake light is on, it may be your clutch or brake.

So, do you have any information about the part released from above?

it's dislodged with the clutch. The socket on the right of the brake appears to be 4.
