Automatic low power consumption mode for combustion tools

A combustion tool having a circuit for conserving battery power, the combustion tool comprising:

• a battery assembly;
• a control circuit;
• at least one of a first switch and a second switch, the first switch configured to be activated when the combustion tool is in a predetermined position and the second switched configured to be activated by actuation of an operator;
• and
• a motion sensing circuit, wherein the control circuit is configured to receive input from the motion sensing circuit and enter into the active state and remain in the active state until a period of time elapses without further input from the motion sensing circuit,
• wherein the control circuit is configured to enter the low power consumption state to conserve battery power, and
• wherein when the control circuit is in the active state, the control circuit is enabled to respond to the one of the first switch and the second switch, and wherein when the control circuit is in a low power consumption state, the control circuit is not enabled to respond to the one of the first switch and the second switch, and
• wherein the control circuit immediately provides power to the tool when movement of the combustion tool is detected.
