Abstract: An electromagnetic relay enables current to pass through switch termini and comprises a coil assembly, a rotor or bridge assembly, and a switch assembly. The coil assembly comprises a coil and a C-shaped core. The coil is wound round a coil axis extending through the core. The core comprises core termini parallel to the coil axis. The bridge assembly comprises a bridge and an actuator. The bridge comprises medial, lateral, and transverse field pathways. The actuator extends laterally from the lateral field pathway. The core termini are coplanar with the axis of rotation and received intermediate the medial and lateral field pathways. The actuator is cooperable with the switch assembly. The coil creates a magnetic field directable through the bridge assembly via the core termini for imparting bridge rotation about the axis of rotation. The bridge rotation displaces the actuator for opening and closing the switch assembly.

Abstract: An electromagnetic relay assembly enables multi-phase switching as achieved by a certain novel assemblies, including a motor assembly and a union transformer assembly, as cooperatively assembled within a housing assembly. The motor assembly comprises a union coil assembly cooperatively assembled with an actuator assembly. The union coil assembly comprises two tandemly-oriented unit coil assemblies as separated by certain stator-guiding structure. The actuator assembly comprises an actuator carriage, two sets of stator assemblies and a plurality of drive bridge assemblies. The stator-guiding structure guides the stator assemblies during actuation and the drive bridge assemblies cooperate with the union transformer assembly to selectively set and/or reset the relay assembly. The union transformer assembly comprises a plurality of unit transformer assemblies, each of which comprises a contact bridge assembly.

Abstract: The electromagnetic relay has a motor assembly with a bobbin secured to a frame. A core is disposed within the bobbin except for a core end which extends from the bobbin. An armature end magnetically engages the core end when the coil is energized. An actuator engages the armature and a plurality of center contact spring assemblies. The center contact spring assembly is comprised of a center contact spring ultrasonically welded onto a center contact terminal. A normally open contact spring is positioned relatively parallel to a center contact spring. The normally open contact spring is ultrasonically welded onto a normally open terminal to form a normally open contact spring assembly. A normally closed contact assembly comprised of a third contact rivet and a normally closed terminal.

A relay motor assembly has an elongated coil bobbin with an axially extending cavity therein. An excitation coil is wound around the bobbin. A generally U shaped ferromagnetic frame has a core section disposed in and extending through the axially extending cavity in the elongated coil bobbin. Two contact sections extend generally perpendicularly to the core section and rises above the motor assembly. An actuator assembly is magnetically coupled to the relay motor assembly. The actuator assembly is comprised of an actuator frame operatively coupled to a first and a second generally U-shaped ferromagnetic pole pieces, and a permanent magnet. A contact bridge made of a sheet of conductive material copper is operatively coupled to the actuator assembly.
