Abstract: A movable spring plate structure for defining an open or closed state with respect to a fixed contact includes a rigid spring plate contact portion, a soft spring plate warp portion, a soft spring plate force-applying portion and a movable contact. The soft spring plate warp portion is coupled to the rigid spring plate contact portion, and a first deformation gap is formed between the rigid and soft spring plate contact portions. The rigid spring plate contact portion is harder than the soft spring plate warp portion. The soft spring plate force-applying portion is disposed at the soft spring plate warp portion, and the movable contact is disposed at the rigid spring plate contact portion. A force applied to the soft spring plate force-applying portion drives the movable and fixed contacts into a closed state.

Abstract: An electromagnetic relay includes a fixed contact part, a movable contact part, an armature, an electromagnet, and a base. The fixed contact part includes a fixed contact. The movable contact part includes a movable contact that faces the fixed contact. The armature is formed of a magnetic material and configured to bring the movable contact into or out of contact with the fixed contact. The electromagnet is configured to generate a magnetic field to move the armature. The base holds the fixed contact part, the movable contact part, and the electromagnet. The electromagnetic relay further includes multiple electrodes configured to generate an electric field between the electrodes.

Abstract: An electromagnetic relay includes a contactor including a fixed contact and a movable contact, and an electromagnet device for moving the movable contact. The electromagnet device includes a coil generating a first magnetic flux by energization, a tubular body including a permanent magnet generating a second magnetic flux in a direction identical to a direction of the first magnetic flux and having a hollow extending in a center axis direction, a movable element disposed in the hollow of the tubular body and reciprocating in the center axis direction, and a yoke forming a magnetic circuit passing together with the movable element and the tubular body. The magnetic circuit allows at least one of the first and second magnetic fluxes to pass through the magnetic circuit. The electromagnet device is configured to, when the coil is energized, move the movable contact to a first position by attracting the movable element with the first magnetic flux and the second magnetic flux. The electromagnet device is configured to, when energization of the coil is suspended, move the movable contact to a second position different from the first position. This electromagnetic relay is easily designed and reduces power consumption at a low cost.
