Abstract
Integral solenoid and starter motor having four or more poles for internal combustion engines has an electrically conductive disc carried by the armature or core of the solenoid for movement in response to energization and de-energization of the solenoid coil. Three stationary contacts of electrically conductive material are disposed in circumferentially spaced relation about the longitudinal axis of the core for sequential engagement by the movable disc. One of the stationary contacts, connected to an electrical energy source, is disposed at a position closer to the movable disc than the other stationary contacts. The other stationary contacts are connected in parallel circuits to two poles of the starter motor whereby each contact carries one-half the current supplied by the energy source. The disc is tiltably mounted on the core for making initial contact with the first stationary contact and later, with the two other contacts in response to the solenoid being energized. When the solenoid is de-energized, the movable disc breaks contact with the other stationary contacts before the first contact whereby the arcing between fixed and movable contacts is minimized.
