摘要： Each movable contact 15 is given a first force by a drive mechanism along a direction for bringing the movable contact into contact with a fixed contact 5 and given a second force through a leg 14b by deformation of a supporting member 14c resulted from an overtravel of the movable plate 14. The fixed contact and the movable contact are arranged such that a resultant force of the first and the second forces acts in a direction normal to a contact surface defined between the fixed contacts and the movable contacts. So, a component force of the resultant force parallel to the contact surface is not generated, therefore, a side slip of the movable contact can be prevented when the contacts are opened or closed.

摘要： A single-pole relay switch capable of effective arc extinction irrespective of the current flowing directions in which the device is connected in a circuit. The switch has a housing and two sets of contacts located in the housing, each set being composed of a fixed contact and a movable contact. A contact carrier is provided to have first and second movable arms which extend commonly from a bridge and are provided respectively with the two movable contacts. An actuator applies a driving force to move the contact carrier between an ON-position of holding the movable contacts simultaneously in contact respectively with the fixed contacts, and an OFF-position of keeping the movable contacts at respective opening gaps from the fixed contacts. The housing includes a casing which is divided into first and second chambers respectively for receiving the contact sets, each of the first and second chambers being surrounded by a dielectric wall. Permanent magnet are disposed around the casing to stretch the individual arcs in opposing directions to each other and towards the dielectric walls of the first and second chambers, respectively. Thus, the individual arcs can be stretched individually within the separate chambers, i.e., in an isolated condition. Therefore, the individual arcs can be free from merging even when the current flows in such a direction as to drive the arcs in the approaching direction.

摘要： A sealed switch has a vessel defining therein a hermetically sealed space which receives a pair of fixed contacts and a movable contact bridging the fixed contact. The movable contact is movable between an ON-position of closing with the fixed contact and an OFF-position of separating from the fixed contacts. Hydrogen gas or hydrogen rich gas is filled in the sealed space in order to suppress arc development between the movable and fixed contacts. The plunger carries at its axial one end the movable contact and carrying at the other axial end an actuator which moves the plunger axially for movement of the movable contact from the OFF-position to the ON-position. An over-travel spring is provided to give a bias for moving the movable contact relative to the plunger in order to develop a contacting pressure between the movable and fixed contacts. The over-travel spring is supported to a spring holder secured to the plunger. The plunger is formed with a threaded portion which extends through the actuator to allow the plunger to move axially relative to the actuator for adjustment of a contact gap between the movable and fixed contact, and the spring holder is formed with stopper protrusions which project in abuttable and slidable relation to the interior surface of the vessel such that the movable contact is prevented from rotating together with the plunger. Accordingly, the spring holder is best utilized to restrict the movable contact from rotating together with the actuator to enable an easy adjustment of the contact gap simply by rotating the actuator.
