<p>Provided is an electrical contact that enables reliable contact between a plunger and a contact spring and ensures smooth operation (up and down action)of a plunger. By means of this electrical contact, electrical tests of electrical parts can be carried out with accuracy. This electrical contact puts the eccentric portion of the rough winding portion of a contact spring, having easy spring deformation in the radial direction, into spring contact with the electrically conductive portion of the plunger. By doing this, the electrically conductive portion of the plunger is elastically interposed between the eccentric portion of the rough winding portion and the fine winding portion. The rough winding portion eccentric-portion and the fine winding portion are always in contact with the electrically conductive portion of the plunger.</p> |
