ABSTRACT:
A fuel cut-off switch is disclosed which comprises a collapsible fuel line for conveying fuel when the switch is in a first position and a device for collapsing the collapsible fuel line along at least a portion thereof to cut off fuel flow therethrough when the switch is tilted a predetermined amount from the first position. The collapsible fuel line may be in the form of a cut-off finger of rubber or plastic which is suspended for movement relative to the device for collapsing the flexible rubber finger, the latter may take the form of a ring surrounding the collapsible fuel line. A weight is attached to the collapsible fuel line for pulling it under force of gravity against the ring to collapse the finger and cut-off fuel flow therethrough.
