摘要： A contact opening and closing device includes a driven contact, a driving contact, and a solenoid actuator. The driving contact is configured to move with respect to the driven contact. The solenoid actuator includes a movable component configured to move to an off position and an on position. When the movable component is in the off position, the driving contact and the driven contact are in a state of non-contact. When the movable component is in the on position, the driving contact and the driven contact are in a state of contact. When the driving contact and the driven contact are switched from a state of non-contact to a state of contact, the movable component moves from the off position to the on position through an overshoot position located beyond the on position.

摘要： An electromagnetic relay (100) has high wear resistance, high corrosion resistance, and good magnetic properties. The electromagnetic relay (100) includes a magnetic component including an alloy layer on its surface formed by diffusion-coating of at least one element selected from the group consisting of Cr, V, Ti, and Al. The alloy layer has a thickness of 5 to 60 µm, inclusive.
