  • Externally-programable switch
    Patent number: 4185260
    Abstract: A magnetically-actuated switch has a stationary mounting base to which a plurality of magnetically-actuated reed-type switches are secured in a layer parallel to the base. A moveable portion of the switch is pivotably mounted to the mounting base, and contains a plurality of magnets positioned to actuate the reed-type switches in any desired sequence. A second layer of magnetically-actuated, reed-type switches is positioned, parallel to the mounting base, below the above-mentioned layer, and additional magnets are added to the moveable portion, to supplement the existing magnets, and increases the magnetic field in certain portions of the moveable portion to effect the lower layer of reed-type switches.
