摘要：Electric disabling circuits and components are provided for preventing theft orunauthorized use of motor vehicles. An auxiliary electrical switch is mounted on thehousing of the ignition or starter key cylinder, and is connected to a fuse in the mainelectrical circuit. When the key cylinder is removed and the ignition or starter switch isshorted, this auxiliary switch causes the fuse to blow out and disable the electrical systemin the vehicle. The ignition or starter switch actuates a relay, which in turn is connected toa valve mechanism in the fuel line and the ignition coil or starter through independentcircuits. Actuation of the relay causes electrical power to be delivered to the fuel valveand ignition coil or starter. When the relay is de-actuated, the ignition coil is grounded,and the vehicle cannot be started with a jumper wire. A further switch is provided fordisabling the relay.
