Claim Text:
1. An arrangement for identifying a switch position of a switch on an internal combustion engine in a handheld work apparatus, the arrangement comprising: a control; an inductive electrical load; an energy source configured to supply said inductive electrical load with energy; said inductive electrical load being connected to said energy source via said control so as to be switched on and off; a first voltage branch disposed parallel to said inductive electrical load; said switch being a first switch having a first and a second switch position and being arranged in said first voltage branch; a first zener diode arranged in said first voltage branch; said first zener diode being configured to be switched to an active state and an inactive state in dependence upon the switch position of said first switch; said inductive electrical load being configured to cause an induced switch-off voltage having an amplitude when said inductive electrical load is switched off; said first zener diode being configured to limit said amplitude of said induced switch-off voltage; and, an evaluation unit configured to evaluate said amplitude of said switch-off voltage which adjusts in dependence upon the position of said first switch.
