Abstract:
1. A solenoid comprising: a first plunger including a first contact bar and an axial aperture; a second plunger including a second contact bar and located at least partially in the axial aperture of the first plunger; a first pair of terminals configured to be connected by the first contact bar when the first plunger has been actuated; a second pair of terminals configured to be connected by the second contact bar when the second plunger has been actuated; a first coil encompassing a portion of the first plunger and the second plunger, wherein the first coil is configured to actuate the first plunger but not the second plunger when a first current flows through the first coil; and a second coil encompassing a portion of the first plunger and the second plunger, wherein the second coil is configured to actuate the second plunger when the first current flows through the first coil and a second current flows through the second coil, wherein the first coil and the second coil are independently energizable.
