Beschreibung
Zusammenfassung:	A power tool (10) includes a housing (12); an electric motor (14); an electronic clutch (40); and a clutch setting assembly (200) that includes a variable resistive element (202), a clutch selector (27), and a contact assembly (204). The contact assembly (204) includes a spring (208) coupled to the clutch selector (27) and a contact member (206) with a leg (224) configured to be insertable into an opening (210) in the clutch selector (27) so that the spring (208) and the contact member (206) are non-removable from the clutch selector (27) and the spring (208) biases the contact member (206) against the variable resistive element (202). The contact member (206) has a head (226) configured to engage the variable resistive element (202) to generate a resistance signal that corresponds to a position of the clutch selector (27). The controller (42) is configured to receive the resistance signal and, based on the resistance signal, look-up, receive, or generate the torque threshold value for the power tool operation parameter that corresponds to the selected clutch setting (27).
