Patent ID: 8667941

Claim:
A fuel cock-integrated engine switch comprising: a fuel shutoff valve ( 2 ) that is provided in a fuel passage supplying fuel to an engine and that includes a valve member ( 3 ) which closes the fuel passage in a first position and which opens the fuel passage in a second position; an operation member ( 11 ) that is operated between an off position for stopping the engine and an on position for operating the engine; a proximity switch ( 12 ) that is provided in the on position; and a permanent magnet ( 14 ) that is attached to at least one of the operation member ( 11 ) and the valve member ( 3 ), wherein the other one of the operation member ( 11 ) and the valve member ( 3 ) to which the permanent magnet ( 14 ) is not attached is formed with a magnetic member, the operation member ( 11 ) and the valve member ( 3 ) are arranged so that, in the off position, a magnetic force exerted by the permanent magnet ( 14 ) acts between the valve member ( 3 ) and the operation member ( 11 ) to make the valve member ( 3 ) shift to the first position whereas, in the on position, the magnetic force exerted by the permanent magnet ( 14 ) does not act between the valve member ( 3 ) and the operation member ( 11 ) to make the valve member ( 3 ) shift to the second position, and an ignition device ( 17 ) is connected to the proximity switch ( 12 ) so that, when the operation member ( 11 ) approaches an operational range of the proximity switch ( 12 ), the ignition device ( 17 ) of the engine is operated whereas, when the operation member ( 11 ) is out of the operational range of the proximity switch ( 12 ), the ignition device ( 17 ) is not operated.
