摘要： A contact device includes a housing, a fixed contact, and a moving contact attached to a support frame, the support frame and moving contact movable within the housing perpendicular to the fixed contact. A stopping arm projects from the support frame to restrict movement of the support frame within the housing.

摘要： A terminal device for connecting an end portion of an exciting coil to an external conductor, said exciting coil being formed on a bobbin and operating, for example, a contact of an electromagnetic contactor. The terminal device includes a terminal base mounted on the bobbin, an electrically conductive terminal plate, and means for mounting the terminal plate to the terminal base such that a force exerted on the terminal plate at its end connected to the external conductor is not transmitted to the end portion of the exciting coil.

摘要： An electromagnetic contactor includes an arc-extinction cover that prevents an electric arc generated during the disconnection of a fixed contact and a movable contact for bridging adjacent fixed contacts. A removable terminal cover serves to cover terminal screws attached to the fixed contacts. The arc-extinction cover and the terminal cover are separate from the contactor body and are attachable and detachable.

摘要： A dust preventing device for an electromagnetic contactor prevents foreign matters accumulated on a foreign matter preventing wall from slipping off the wall due to vibrations of electromagnetic contactor. In a case where an arc extinguishing chamber cover is disposed to cover a fixed contact and a movable contact, and includes a foreign matter preventing wall provided under a gas discharging opening formed on the cover, the foreign matter preventing wall is formed with ribs provided therearound in a shape of an embankment. Therefore, foreign matters having entered through the gas discharging opening can be positively trapped in a hollow portion surrounded by ribs, so that the foreign matters do not fall into the electromagnetic contactor from the foreign matter preventing wall due to vibrations of the contactor.
