ABSTRACT:
A magnetically coupled switch that utilizes a flex armature has a user manipulated holder that carries at least one magnetic coupler made of magnetic material. The flex armature is a substantially flat piece of flexible magnetic material that is magnetically attracted to the at least one magnetic coupler. A carrier layer having electrical conductors formed thereon is intermediate the flex armature and magnetic coupler such that the electrical conductors are electrically connected by the flex armature where the flex armature is magnetically attracted to the magnetic coupler. In the absence of a magnetic coupler, the flex armature is normally spaced from the electrical conductors on the carrier layer. Preferably, there is a bottom cover that encloses a cavity that contains the flex armature, and the bottom cover includes at least one shock dimple that secures at least part of the flex armature to the carrier layer. The electrical conductors on the carrier layer are arranged within the switch so that the flex armature is movable into and out of shorting relationship with the electrical conductors to change the circuit logic for a circuit incorporating the switch.
