Provided is a connection unit including an electromagnetic relay and a bus bar connected to the electromagnetic relay. In such a connection unit, a first bus bar connected to a first fixed contact terminal is disposed facing one surface of a movable touch piece located on an opposite side of the movable touch piece from the other surface of the movable touch piece in a contact-making and breaking direction, with a gap provided between the first bus bar and the movable touch piece in the contact-making and breaking direction, the first bus bar extends in a direction that intersects the contact-making and breaking direction and in which a first movable contact and a second movable contact of the movable touch piece are arranged, and at least part of the first bus bar lies over the movable touch piece in plan view in the contact-making and breaking direction.

A reed switch is positioned within a housing and an actuation or drive coil is wrapped around a central portion of the housing. A permanent magnet for biasing or holding the reed switch contact in a closed positioned is mounted in the housing outside of and spaced apart from the coil and in direct mechanical contact with a bare uninsulated portion of one of the reed switch leads.

An electromagnetic relay including: a relay body that includes a first terminal; a base that includes a second terminal which contacts the first terminal and supports the relay body; an outer cover that covers the relay body; and an elastic member that is attached between the relay body and the outer cover.

A power relay for a vehicle has a housing and two connecting bolts that are introduced into the housing so as to contact a load current circuit. The power relay further having a coil assembly that is arranged in the housing, the coil assembly contains a magnetic coil and a magnetic armature that is coupled by way of a force-transferring member to a contact bridge that can be moved in a reversible manner between a closed position and an opened position and can be displaced in the housing under the effect of a magnetic field that is generated by the magnetic coil. The contact bridge supports two contact elements that together with the mating contacts of the connecting pin form a first contact pair and a second contact pair. The contact pairs form a three point bearing arrangement in the closed position.

An electromagnetic relay includes an electromagnet unit, a contact unit including a movable contact spring with a movable contact provided thereon and a fixed contact spring with a fixed contact provided thereon, and a base block configured to support the electromagnet unit and the contact unit, wherein the electromagnet unit is supported at a first face of the base block, and the contact unit is supported at a second face of the base block facing in an opposite direction from the first face, and wherein the base block includes a first insulating wall extending from the first face alongside the electromagnet unit and a second insulating wall extending from the second face alongside the contact unit, the second insulating wall being situated on an opposite side from the first insulating wall across the second face.

An electrical power contactor including a local electrical ground plane configured to be electrically connected to a reference potential 0Vdc of an electrical power supply of the power contactor. Current returns from at least one coil and from at least one auxiliary contact of the electrical power contactor are formed by a common conductor that is connected to the local electrical ground plane. A current return from a controller of the electrical power contactor is also connected to the local electrical ground plane.

There is provided a rail attachment apparatus for an electrical device in which a biasing elastic function is imparted to a slider itself, whereby the slider can be adjusted to be thin and the number of components can be decreased. The rail attachment apparatus includes a nipping portion that nips one side edge of an attaching rail fixed to an attaching surface of the electrical device, and a slider that is opposed to the nipping portion and slidably held at the other side edge of the attaching rail in a direction intersecting with this attaching rail. The slider is provided with integrally formed bending elastic portions which bias the slider in a direction to enable nipping the attaching rail.
