Patent ID: 7107963

Claim:
An ignition assembly for a portable power tool having a carburetor and an ignition circuit comprising: a choke lever connected to an air valve for controlling the flow of air to the carburetor, the choke lever being reciprocally movable between a first position in which air flow to the carburetor of the portable power tool is not substantially restricted and a second position in which air flow to the carburetor is substantially restricted, the choke lever including a depending abutment; an ignition switch positioned on a mounting element in the portable power tool so as to be movable between a run position in which the power tool may be operated and a stop position in which the power tool may not be operated, the ignition switch including a depending abutment located in the line of reciprocal movement of the depending abutment of the choke lever when the ignition switch is in the stop position so that reciprocal movement of the choke lever from the first position to the second position causes the depending abutment on the choke lever to engage the depending abutment on the ignition switch and move the ignition switch from the stop position to the run position; and a leaf spring engaging the ignition switch at a first site of engagement on the ignition switch when the ignition switch is in the stop position and engaging the ignition switch at a second site of engagement on the ignition switch when the ignition switch is in the run position, the leaf spring being biased for alternatively applying a force to the ignition switch at the first and second sites of engagement in a direction toward the mounting element and away from the choke lever.
