Abstract
In a distributor cap for internal combustion engines, a multi-positionable contact which can be manually rotated to successively present each of a plurality of contact surfaces to the distributor arm after an adjacent contact surface has become pitted, corroded or otherwise worn; thus increasing the useful life of the distributor cap. The contact surfaces are symmetrically arranged about the axis of rotation of the contact. Rotation can be achieved by means of a screwdriver blade introduced through the sparkplug wire terminal to act on a slotted head of the rotating contact exposed at the bottom of the sparkplug wire terminal, or by grasping the contact from underneath.
