Abstract
A switch includes a switch housing, and a button moveably mounted to the housing. A profile is disposed on the underside of the button and has a profile contour that provides the tactile feel of the button as it is engaged by the user. A spring biased plunger has one end that engages the profile contour. A printed circuit board is mounted to the housing and includes a magnet sensor. A magnet holder includes at least one magnet. A vane interrupter has at least one passage having an opening proximate to a magnetic sensor. The magnet holder is moveably mounted to the housing such that the magnet is selectively moveable at least partially within the passage to a position where the magnet can be detected by the sensor.
