Abstract
A power tool includes a leveling mechanism that determines horizontal or vertical planes of the power tool. The leveling mechanism has a housing with a cavity in the housing. A rotating member is in the housing. The rotating member moves in the cavity such that the rotating members seeks an equilibrium position. The equilibrium position corresponds to a horizontal or vertical plane. Electrical contacts are coupled with the rotating member such that the electrical contacts only complete an electrical circuit when the rotating member is in the equilibrium position. An indicator is electrically coupled with the electrical contacts to indicate to the user when the mechanism is in an equilibrium position. A power source is coupled with the electrical contacts and the indicator to energize the indicator when the circuit is complete.
