  • Publication number: 20100224466
    Abstract: A portable handheld work apparatus has an internal combustion engine (7) which includes an ignition system. An operating-mode position selector (55) is provided which closes a first switch (76) in a first position and closes a second switch (77) in a second position. The first switch (76) includes a first contact (39) and the second switch (77) includes a second contact (40). A simple and robust configuration is provided when the first contact (39) and the second contact (40) are formed on the operating-mode position selector (55).
