Miniature electromagnetic assembly and relay with the miniature electromagnet assembly

In a miniaturized electromagnet comprising:

• an L-shaped flat magnetic plate of magnetic material with a horizontally extending core and a first yoke leg integrally depending from one end of said core, said L-shaped magnetic plate and first yoke leg lying in a first plane;
• a coil assembly with an excitation coil dispersed around said core to define a coil thickness extending horizontally perpendicular to the length of said core;
• a second yoke leg made of magnetic material and depending from the other end of said core in an opposed relation to said first yoke leg;
• and
• an armature bridging between said first and second yoke legs in parallel with the length of said core, said armature having a pivot end and a pole end at opposite ends thereof and pivotally supported at said pivot end adjacent to the first yoke leg with said pivot end in constant magnetic coupling to said first yoke leg such that said armature is pivotable about said pivot end in a horizontal plane parallel to a plane of said core within said coil thickness between a set position and a reset position of having said pole end attracted to and spaced away from said second yoke leg upon energization and deenergization of said excitation coil, respectively;
• said second yoke leg being of a flat plate configuration having a general plane extending perpendicular to said first plane and to have its lower end portion bent to define thereat a pole plate which is disposed in a plane parallel to said pole plate being positioned in an overlapping relation to said pole end of said armature for attaching said pole end to said pole plate upon energization of said excitation coil.
