Solenoid with an improved contact design and a system utilizing the solenoid |
摘要 |
In one embodiment of the present invention, a starter motor solenoid includes two fixed contacts and a movable contact. The movable contact and one fixed contact are made of copper. The other fixed contact is made of steel. Over a relatively few cycles of the starter motor solenoid, a coating of copper is deposited from the movable contact to the steel fixed contact. Thus, despite the use of relatively inexpensive steel as fixed contact material, a highly-conductive and reliable junction is provided between the movable contact and the steel fixed contact.
