Abstract
A brake is provided that employs an electromagnetic or magnetic circuit to disengage the brake and in which a reed switch is used to indicate an operating condition of the brake. The reed switch is positioned across an air gap between two members of the electromagnetic or magnetic circuit. The reed switch is oriented such that a longitudinal axis of the reed switch extends in a direction other than parallel to one or both of (i) the axis of rotation for rotating components of the brake and (ii) a direction of a magnetic force at a point in the air gap where the magnetic force is greatest.
