The electromagnetic relay includes a contact unit, an electromagnet, an armature unit, and a base. The contact unit includes a fixed contact and a movable spring including a movable contact. The armature unit is movable in accordance with excitation of the electromagnet to allow the movable contact to move between a closed position in contact with the fixed contact and an open position away from the fixed contact. The base holds the contact unit and the electromagnet on a certain surface side. The movable contact is placed between the base and the fixed contact in an arrangement direction in which the base and the electromagnet are arranged. The armature unit includes a press part which causes movement of the movable contact by applying a pressing force to a certain surface facing the fixed contact, of the movable spring.

An actuator, which is a part of a combination that includes a pair of circuit interrupters, advantageously employs a plurality of Thomson coils that are electrically connected in parallel and that interact with a corresponding set of Thomson plates of a rotatable armature in order to perform useful work in a rapid fashion. In one embodiment, the useful work is to commutate current from one circuit interrupter to the other.

A modular family of electrical switching relays that utilize interchangeable mechanical override knobs or blank fillers, combined with enclosures capable of containing two or more independently operable relays; where each independent operating relay can selectively be constructed to either have a mechanical override knob or to have a blank filler thus resulting in a broad number of product permutations from a minimum number of unique components that are required to build those permutations. An electromechanical relay with rotary manual on and off override control where the manual on and off control consists of three distinct positions for (1) forcing/maintaining the relay on, (2) forcing/maintaining the relay off, and (3) allowing the relay to automatically turn on and off or to be remotely turned on and off with an electrical signal. An electromechanical push/pull relay with manual on and off override control where the axis of rotation of the manual override control is perpendicular to the axis of relay push/pull direction.

An armature for an electromagnetic actuator, the armature including an armature body, at least one electrically conductive member configured for cooperation with a magnetic field generator of an electromagnetic actuator, and a connection end configured for connection of the armature to an apparatus operable by an electromagnetic actuator. The armature body also having a cellular structure. The armature may form part of an electromagnetic actuator, which in turn may be a component in a switch device. The armature may be manufactured by an additive manufacturing process.
