Abstract: An electrical switch has spaced, facing coupler and carrier layers with a set of electrodes formed on the facing surfaces thereof. There is an aperture in the coupler layer. A conductive armature is disposed in the space between the coupler and carrier, aligned with the aperture. The coupler is a magnet and the armature is made of magnetic material so the armature is normally held in engagement with the coupler. A user can press on any part of the armature through the aperture to cause a first portion of the armature to break away from the armature and contact the electrodes on the carrier while a second portion of the armature remains in contact with the coupler. The electrodes are arranged to provide an output which is dependent upon the location of contact with the armature.

Abstract: An electrical switch has a set of electrodes mounted on one side of a carrier. The opposite side of the carrier mounts an actuator having a plunger mounted for reciprocating motion. The plunger carries a coupler in the form of magnets. A conductive armature of magnetic material is disposed on the electrode side of the carrier. When the plunger withdraws the coupler magnets from the carrier, the armature is free to fall out of contact with the electrodes. A retention cover maintains the armature in the vicinity of the carrier such that subsequent movement of the coupler proximate the carrier will draw the armature back into contact with the electrodes.

Abstract: A magnetically actuated switch has a carrier sheet with electrodes on one side thereof and an actuator knob on the other side. Magnets carried by the knob drag an armature around on the electrodes. A retainer for the knob permits physical or logical relocation of the knob with respect to the carrier sheet.

Abstract: An electrical switch has a substrate with at least one pair of spaced switch contacts arranged to be shorted by an electrically conductive armature. The armature defines a central axis with first and second portions on either side of the axis which portions terminate at first and second edges. The armature is normally held spaced from the contacts by magnetic attraction to a coupler layer disposed in spaced relation to the substrate. The armature is movable by an actuating force to engagement with the substrate. The armature separates from the coupler layer by a double pivoting motion. An actuating force applied to the armature remote from its central axis causes one edge of the armature nearest the actuating force to break away from the coupler layer. The armature then pivots about the opposite edge of the armature until the one edge bottoms on the substrate.

Abstract: A switch has a carrier sheet with electrodes formed on an internal side thereof to form switch contacts. An armature is held in slidable contact with the internal side of the carrier and the electrodes by a magnet disposed on the external surface of the carrier. The magnet is carried in a knob mounted on the external side of the membrane carrier for rotary, linear or complex motion. When a user manipulates the knob the magnet drags the armature 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 by a magnet. A membrane and spacer may be added to protect and seal the electrodes and armature.
