Abstract:
A power tool leveling device, comprising:a housing, a cavity in said housing; a rotating member in said housing, said rotating member moving in said cavity such that said rotating member seeks an equilibrium position which corresponds to a level position; at least one member associated with said rotating member for enabling passage of a beam through said rotating member; an electrical circuit including an emitting device, a receiving device, and an indicator device electrically coupled such that upon activation, said emitting device emits a beam which passes through said at least one member, said beam received by said receiving device which, in turn, activates said indicator device indicating to a user that said leveling device is in or near an equilibrium position and said electrical circuit further including a device for varying current to said indicator device such that as the beam intensity at the receiver device increases, the indicator device increases in intensity; and a power source coupled with said electrical circuit for energizing said electrical circuit.
