Abstract
An apparatus that determines that a vehicle has moved comprises a shaft member, a pin configured to attach the shaft member to a backing plate via an opening in the shaft member that enables the shaft member to move in a direction along the length of the shaft member, to rotate about the pin, and to contact a surface external to the vehicle when the shaft member is in a first position. The apparatus also comprises a first alignment magnet that attracts the shaft member to the surface external to the vehicle and a first sensor that determines that the shaft member is in the first position. The apparatus further comprises a first holding magnet, a second holding magnet, and at least one sensor that indicates that the shaft member is in contact with the first holding magnet or the second holding magnet, each indicating a direction of movement.
