Abstract: A contact device includes a moving contactor, a pair of moving contacts arranged in one direction, a pair of fixed terminals, and a pair of fixed contacts. At least one fixed terminal, selected from the pair of fixed terminals, includes a contact holder. The contact holder includes a first fixed extension and a second fixed extension. As for either a current component flowing in the one direction into the fixed contact or a current component flowing in the one direction out of the fixed contact, the current component flowing through the first fixed extension has a larger amount of current than a current component flowing through the second fixed extension.

Abstract: The electromagnetic relay comprises an auxiliary fixed terminal that has a configuration different from that of a fixed terminal and includes an auxiliary external input/output terminal and an auxiliary external output/input terminal that can be electrically connected to the auxiliary external input/output terminal. The electromagnetic relay comprises an auxiliary movable terminal that has a configuration different from that of a movable terminal and can electrically connect the auxiliary external input/output terminal and the auxiliary external output/input terminal.

Abstract: An electromagnetic relay includes plural pairs of fixed terminals each including an external input/output terminal and an external output/input terminal that can be electrically connected to the external input/output terminal the external input/output terminal and the external output/input terminal being paired with and separated from each other. A tip portion of the external input/output terminal and a tip portion of the external output/input terminal paired with each other are aligned along a straight line extending in a direction substantially parallel to a virtual straight line in a plan view, and the straight lines on which the respective pairs of the tip portions are aligned are offset from each other in a direction vertical to the virtual straight lines.
