Abstract
A magnetically coupled pushbutton switch having hard electrical conductors is discrete and may be used in place of a dome tact switch. The hard electrical conductors of the magnetically coupled pushbutton switch are uniquely arranged and may be soldered to a circuit board or surface mounted. Additionally, modifications and improvements made to the switch allow it to maintain good tactile response even though the switch may be as compact as a smaller tactile dome switch. A further benefit of the switch is its ability to be normally open, normally closed, or both. This capability stems from the unique arrangement of the hard electrical conductors that, in one preferred embodiment, extend over the top of a magnetically coupled switch armature. All of the hard electrical conductors are arranged within the switch so that the pushbutton armature of the switch is movable into and out of shorting relationship with the electrical conductors to change the circuit logic for a circuit incorporating the switch.
