Abstract:
A bore rider switch mounted within a vehicle, the vehicle being capable of being launched from a tube, the switch providing a signal when the vehicle exits the tube, the switch comprising:a mounting for attaching the switch within the vehicle;a plunger movable in relation to the mounting, the plunger having a first end interacting with an interior surface of the tube when the vehicle is within the tube;at least one first contact attached to and moving with the plunger;at least one contact switch means attached to the mounting, the contact switch means being in an open position when the plunger end is interacting with the interior surface of the tube; andbiasing means for biasing the at least one first contact in a direction towards the at least one contact switch means, the direction corresponding with movement of the plunger end away from the vehicle and towards the interior surface, the interaction of the plunger end and the interior surface of the tube maintaining a separation between the at least one first contact and the at least one contact switch means, the exiting of the vehicle from the tube allowing the biasing means to move the plunger in relation to the mounting, the movement forcing the at least one first contact against the at least one contact switch means to place the at least one contact switch means in a closed position, the closed position completing a circuit for providing the signal.
