An electromagnetic relay includes a base, a casing, a coil, a movable contact piece and two fixed contact pieces. Each of the fixed contact pieces includes a plate-shaped base. A portion of one side of the plate-shaped base extends outward and is bent to form a fixed contact fixing part. The fixed contacts are arranged on the fixed contact fixing part, and an abdicating through hole is defined in the base. The plate-shaped bases of the fixed contact pieces are respectively connected to an outer side surface of the base and spaced from each other. Each of the fixed contact fixing parts protrudes through the abdicating through hole and located between the base and the casing. Each of the fixed contacts faces to the movable contact on the movable contact piece, and a portion of the plate-shaped base on the fixed contact piece protrudes out of the casing to form a connecting part.

The present disclosure provides a circuit assembly that has a novel structure, with which it is possible to prevent the occurrence of a problem caused by an excessive repulsive force of a heat conductive member by controlling the repulsive force of the heat conductive member. A circuit assembly includes: a heat generation component; bus bars that are connected to connecting portions of the heat generation component; an insulating base member that holds the heat generation component and the bus bars; and an elastic heat conductive member that is in thermal contact with the bus bars. The bus bars press the heat conductive member in a mounting direction in which the bus bars are mounted on the base member. As a result of the bus bars abutting against bus bar positioning portions provided on the base member, the positions of the bus bars in the mounting direction are defined.

A high-voltage relay system for a vehicle is provided. The system includes a relay, a first contact part positioned between a battery and a power converter, a voltage application unit, and a second contact part positioned between the voltage application unit and the ground. A first resistor is connected, at a first end thereof, in series to a second end of the second contact part and connected, at a second end thereof, to the ground. A controller operates the relay in response to an ON/OFF control signal to short-circuit or open the contacts at both ends of the first contact part or the contacts at both ends of the second and determines whether the relay fails based on the type of the ON/OFF control signal and the voltage value between both ends of the first resistor.
