Abstract
A safety switch is provided to detect when a tube launched which exits the tube. The switch is located within the vehicle having a switch plunger extending to the periphery of the vehicle. The plunger is biased to provide outward pressure against a lever on the exterior of the vehicle. The lever rides within the bore of the launch tube such that, when the vehicle is within the launch tube, the lever contacts the interior bore of the tube. The lever contacting the tube bore prevents the plunger from extending to activate the switch. When the vehicle exits the tube, the lever is free to rotate away from the vehicle allowing the plunger to extend and activate the switch which may be a single or multi-pole switch.
