1. A reusable vibration and shock resistant electrical contact for connecting integrated-circuit leads to balance of circuit components, comprising:

  • a bimetallic contact with a barbed end, fabricated with a contact shape such that the barb end protracts with increasing temperature and retracts with decreasing temperature, said barb end pointing toward the direction of insertion of an integrated circuit lead so as to prevent by mechanical force of the barb end against said circuit lead the pulling out of the lead from the contact when the barb end is protracted and said retracting with decreasing temperature being sufficient to disengage the barbed end from the integrated circuit lead below a designed removal temperature;

    a conducting base with one end connected rigidly to said bimetallic contact;

    a tab connected rigidly to a second end of said base in such a manner that the barb end of the bimetallic contact and the tab form an integrated circuit lead-insertion-region with the barb just touching the tab at minimum design temperature; and

    a contact extension protruding from the under side of said base for making electrical contact with balance-of-circuit components;

    said bimetallic contact, said base, said tab, and said contact extension being configured so as to seat rigidly in a mounting recess in a non-conducting socket body.
