Abstract: This contact device includes: a first fixed terminal; a movable contactor configured to contact the first fixed terminal and separate from the first fixed terminal; a spring disposed below the movable contactor and formed of a metal; a holder including a bottom and disposed to position the bottom below the spring; and a resin member configured to cover a portion of the bottom of the holder. The holder has a higher thermal conductivity than a thermal conductivity of the resin member. The upper surface of the bottom of the holder includes an exposed portion that is exposed from the resin member. The spring is in contact with the exposed portion of the bottom.

Abstract: An electromagnetic relay includes an electromagnet device, a contact device, and a trip device. The electromagnet device includes a first stator, a movable element, and a first exciting coil. The contact device includes a movable contact and a fixed contact. A trip device includes a second exciting coil. The electromagnet device moves the movable element from a first position to a second position. The trip device moves the movable element to a third position. An open state is reached when the movable element is in the first position and the third position. A closed state is reached when the movable element is in the movable element is in the second position.
