Abstract:
A battery-powered tool (200) may include a first tool-side electrical contact (251), a battery detection switch (220), a tool load (300), and a load connection switching device (210). The load connection switching device (210) may be configured to make an electrical connection between the first tool-side electrical contact (251) and the tool load (300) in response to a state change of the battery detection switch (220). The tool (200) may define engagement positions with the battery (110). In the first engagement position, a first battery-side electrical contact (111) is electrically coupled to a first tool-side electrical contact (251), and the battery detection switch (220) is not physically engaged. In the second engagement position, the first battery-side electrical contact (111) is electrically coupled to the tool-side electrical contact (251), and the battery detection switch (220) is physically engaged to cause a state change of the battery detection switch (220).
