| 20110227676 | Forced Return Solenoid - A forced return solenoid that includes an electrical winding configured to create an electromagnetic field when electrical current flows through the winding, an electrical terminal configured to be connected to a source of electrical energy, and a moveable contact plate configured to be moved into contact with the electrical terminal. Embodiment of the forced return solenoid include a plunger configured to move axially in response to the electromagnetic field generated by the electrical winding. Movement of the plunger in one direction causes the moveable contact plate to connect with the electrical terminal. Movement of the plunger in the opposite direction causes an impact intended to break the connection between the moveable contact plate and the electrical terminal. Embodiments of the forced return solenoid further include a return spring configured to move the plunger in the second direction, wherein the impact means comprises a removable snap ring affixed to the plunger. | 09-22-2011 |
