Magnetic tether switch

An apparatus, comprising:

• a base comprising:
• a first housing having a top side;
• and
• a first magnetic assembly slidably contained within a cavity of the first housing, wherein the first magnetic assembly comprises a first magnet and a first magnetic flux return component;
• and
• a cap comprising:
• a second housing having a bottom side, wherein the second housing comprises a housing extension that extends below the bottom side of the second housing by a first distance;
• and
• a second magnetic assembly at least partially within the second housing, wherein a magnetic field strength of the second magnetic assembly at the first distance is less than a weight of the cap,
• wherein the base further comprises:
• a circuit comprising a plurality of contacts, wherein the first magnetic assembly connects the plurality of contacts together in one of a first state or a second state and disconnects the plurality of contacts from each other in the other of the first state or the second state, the first state corresponding to the first magnetic assembly being in a first position within the cavity when the cap is magnetically attached to the base and the second state corresponding to the first magnetic assembly being in a second position within the cavity when the cap is detached from the base;
• and
• a state retention component that holds the first magnetic assembly in the second state when the cap is not magnetically attached to the base.

An apparatus, comprising:

• a base comprising:
• a first housing having a top side;
• a first magnetic assembly slidably contained within a cavity of the first housing, wherein the first magnetic assembly comprises a first magnet having a first polarity orientation and a second magnet having a second polarity orientation;
• and
• a cap comprising:
• a second housing having a bottom side, wherein the second housing comprises a housing extension that extends below the bottom side of the second housing by a first distance;
• and
• a second magnetic assembly at least partially within the second housing, wherein a magnetic field strength of the second magnetic assembly at the first distance is less than a weight of the cap,
• wherein the base further comprises:
• a circuit comprising a plurality of contacts (42, 44), wherein the first magnetic assembly connects the plurality of contacts (42, 44) together in one of a first state or a second state and disconnects the plurality of contacts (42, 44) from each other in the other of the first state or the second state, the first state corresponding to the first magnetic assembly being in a first position within the cavity when the cap is magnetically attached to the base and the second state corresponding to the first magnetic assembly being in a second position within the cavity when the cap is detached from the base;
• and
• a state retention component that holds the first magnetic assembly in the second state when the cap is not magnetically attached to the base.
