Abstract:
1. A battery-powered portable tool, comprising: a housing, a driven element supported by the housing, an electric motor coupled to the driven element to selectively drive the driven element, a battery providing a power source for the electric motor when selectively coupled to the electric motor, and a control circuit configured to enable selective coupling of the battery to the electric motor, wherein the control circuit comprises at least a main switch and a first auxiliary switch, the main switch being operable to provide the selective coupling of the battery to the electric motor based at least in part on a position of the first auxiliary switch, and wherein the first auxiliary switch is operable based on a position of a protruding member having a folded-in position and a protruding position relative to the housing, the first auxiliary switch enabling the main switch to selectively couple the battery to the electric motor responsive to the protruding member being in the folded-in position and preventing the main switch from selectively coupling of the battery to the electric motor responsive to the protruding member being in the protruding position.
