Abstract

An object of the present invention is to provide a contact switching device in which a short circuit contingent to flow-out of scattered objects caused by arc is eliminated, so that life durability is increased. For this, there is provided a contact switching device in which a movable iron core provided at one end portion of a movable shaft is attracted to a fixed iron core, based on excitation and degauss of an electromagnet portion, by which the movable shaft reciprocates in a shaft center direction, and movable contacts of a movable contact piece arranged at another end portion of the movable shaft contact and depart from fixed contacts. Particularly, contact surfaces between the fixed contacts and the movable contacts are arranged inside a box-shaped insulating member, and an opening portion of the insulating member is closed by a lid body having at least one extending portion in a direction of an arc generated between the fixed contacts and the movable contacts.
