I have a 1983 Porsche S928. At the end of the throttle cable there is an open closed
, can someone tell me its function. In my car the throttle does not touch it under any circumstances so it is not used
It's the idle microswitch and adjusts the fuel mixture when idling. You can adjust the throttle cable so that it activates the switch when your gas pedal is released.

New switches are NLA. They also don't do much so you can probably just ignore it.
From LJet Manual:
Throttle Valve Switches - A: Idle Contact
This contact is used to shut off the fuel supply when coasting. The idle switch will open when the accelerator linkage play is eliminated, before the throttle valve is opened.
