A bi-stable relay assembly, comprising:
- a housing;
- and
- a core assembly within the housing, the core assembly comprising:
- a coil support structure comprising a first end section and a second end section each connected to a central section;
- a first coil and a second coil along the central section of the coil support structure;
- a first magnet positioned within the first end section of the coil support structure;
- a second magnet positioned within the second end section of the coil support structure;
- and
- a first electromagnetic shell component and a second electromagnetic shell component each extending between the first and second magnets, wherein the first electromagnetic shell component is positioned within a first end first recess of the first end section and a within second end first recess of the second end section, and wherein the second electromagnetic shell component is positioned within a first end second recess of the first end section and within a second end second recess of the second end section.
A core assembly for a relay, the core assembly comprising:
- a coil support structure comprising a first end section and a second end section each connected to a central section;
- a first coil and a second coil extending around the central section of the coil support structure;
- a first magnet positioned within the first end section of the coil support structure;
- a second magnet positioned within the second end section of the coil support structure;
- and
- a first electromagnetic shell component and a second electromagnetic shell component each extending between the first and second magnets, wherein the first electromagnetic shell component is positioned within a first end first recess of the first end section and a within second end first recess of the second end section, and wherein the second electromagnetic shell component is positioned within a first end second recess of the first end section and within a second end second recess of the second end section.
A core assembly, comprising:
- a coil support structure;
- a first coil and a second coil wound about a central section of the coil support structure;
- a first magnet and a first ferromagnetic plate within a first end section of the coil support structure;
- a second magnet and a second ferromagnetic plate within a second end section of the coil support structure;
- a first electromagnetic shell component and a second electromagnetic shell component each in contact with the first and second magnets;
- a plunger extending through the first and second coils and between the first and second magnets;
- and
- a first core shaft surrounding the plunger, wherein a spring is positioned within the first core shaft, wherein a first end of the spring is in contact with a flange of the plunger, and wherein a second end of the spring is in contact with the second ferromagnetic plate.
