<p>A switch (10) has a carrier sheet (16) with electrodes formed on an internal side thereof to form switch contacts. An armature (18) is held in slidable contact with the internal side of the carrier (16). The magnet (30) is carried in a knob (22) mounted on the external surface of the carrier (16) for rotary, linear or complex motion. When a user manipulates the knob (22) the magnet (30) drags the armature (18) either into or out of shorting relation with the electrodes. A magnetic detent gear can be incorporated to provide tactile feedback. A pushbutton version of the switch can be made with a pivotable armature normally held spaced from electrodes on the substrate (12) by a magnet (30). A membrane (16) and spacer (14) may be added to protect and seal the electrodes and armature (18).</p> |
