Abstract

A solenoid includes a solenoid housing defining a solenoid centerline; and an ignition magnetic switch including an ignition magnetic switch coil disposed at least partially within the housing, the ignition magnetic switch coil having a magnetic field that encompasses the solenoid centerline.

Claims

1. A solenoid comprising:

a solenoid housing defining a solenoid centerline; and

an ignition magnetic switch including an ignition magnetic switch coil disposed at least partially within the housing, the ignition magnetic switch coil having a magnetic field that encompasses the solenoid centerline.

2. The solenoid of claim 1 wherein the ignition magnetic switch coil physically encompasses the solenoid centerline.

3. The solenoid of claim 1 wherein the ignition magnetic switch coil physically surrounds the solenoid centerline.

4. The solenoid of claim 1 wherein the ignition magnetic switch coil intersects the solenoid centerline.

5. The solenoid of claim 1 wherein the ignition magnetic switch coil is contained within a tubular shape defined by the solenoid housing and the solenoid centerline and with the solenoid centerline outside of the ignition magnetic switch coil.

6. The solenoid of claim 1 wherein the ignition magnetic switch coil is substantially U-shaped.

7. The solenoid of claim 1 wherein the ignition magnetic switch coil is of an angular geometric shape.

8. The solenoid of claim 7 wherein the angular geometric shape is pentagonal.

9. The solenoid of claim 1 wherein the solenoid includes a plunger, the plunger being disposed within the magnetic field of the ignition magnetic switch coil.

10. The solenoid of claim 1 wherein the solenoid includes a plunger, the plunger being disposed within the ignition magnetic switch coil.
