Abstract
A switch includes a switch housing, a button, a circuit board having at least one magnet sensor, and a magnet holder, including at least one magnet, movably mounted to the housing to move responsive to an actuation of the button. A vane interrupter in the switch includes a passage structure positioned proximate to each magnet sensor such that a respective magnet is movable at least partially within a passage defined by the passage structure, and a flange structure having a first flange and a second flange positioned on opposing ends of the passage structure, with the first flange positioned adjacent a portion of the magnet holder holding the magnet and with the second flange positioned adjacent a surface of the circuit board opposite a surface on which the at least one magnet sensor is positioned, such that the circuit board is positioned between the magnet holder and the second flange.
