| PROBLEM TO BE SOLVED: To reduce a burden on a switching mechanism of a double-break contactor apparatus and to achieve a size reduction thereof. SOLUTION: A first movable contactor 2, a fixed contactor 5 and a second movable contactor 7 are arranged in an S-shape. The first movable contactor 2 has an end provided with a movable contact 2a and the other end rotatably supported by a pivot shaft 3, and is driven to be opened/closed by the switching mechanism. The fixed contactor 5 has an end provided with a fixed contact 5a and the other end provided with a terminal 6. The second movable contactor 7 has an end provided with a first movable contact 7a and the other end provided with a second movable contact 7b, and is rotatably supported therebetween by a pivot shaft 8. The first movable contactor 2 is energized by a contact spring 11 to the second movable contactor 7, and the second movable contactor 7 is energized by a contact spring 12 to the first movable contactor 2 and the fixed contactor 5. When a large current such as a short circuit current flows, the first and second movable contactors 2, 7 rotate against the contact springs 11, 12 due to an electromagnetic repulsive force among currents flowing through the contactors 2, 5 and 7, so that the contacts become apart from each other without awaiting the opening operation of the switching mechanism.

| PROBLEM TO BE SOLVED: To solve the problem that a switching device with a movable contact generates arc discharge when voltage for switching the contact goes beyond arc voltage specific to a material constituting the contact, and the arc discharge causes degradation of a contact part. SOLUTION: The switching device comprises a movable contact (7), fixed contacts (8), (9), and a variable resistor element (20) fitted between the both movable and fixed contacts. The variable resistor element (20) forms a conductive path in the switching device before the contacts (7), (8), (9) come to a contact state by decreasing resistance as it receives pressing force by the moving movable contact (7).

| PROBLEM TO BE SOLVED: To provide an electromagnetic relay of a simple structure which surely applies/cuts off a high-load voltage. SOLUTION: First and second fixed contact terminals 51 and 52 are fitted to a resin base block 10. Forked first and second movable pieces 45 and 46 are fitted on the lower side of a hanging part 43 of a spring member 40. When a coil is not excited, the first and second movable pieces are abutted on a back stop plate 11, being away from first and second fixed contact elements, and are not energized. When the coil is excited, contact elements 45a and 46a attached to the first and second movable pieces make contact with elements 51a and 52a attached to the first and second fixed contact elements, resulting in continuity between the first fixed contact terminal and the second fixed contact terminal.

| PURPOSE: To open a circuit without causing any generation of arc by shunting a main contact by means of auxiliary contact networks, inserting a dielectric member into a clearance between contacts, and performing the last shutdown after the last network for the auxiliary contact is opened. CONSTITUTION: After a main contact 1, which is connected to networks 2, 3 for auxiliary contacts 4 and an electric current control resistor 5 in parallel so as to be shunted, is opened, the open circuit current is let flow through the circuit networks 2, 3 and the resistor 5. Therefore, the main contact 1 is opened without any generation of an arc, and sparks generated during opening circuit is sheared by means of a dielectric member 9. Subsequently, the auxiliary contact 4 in the network 2 is opened, so that shunt is carried out by means of the network 3 and the resistor 5. After the auxiliary contact 4 in the circuit network 3 is opened, the open current is restricted so as to pass through the resistor 5. The last shutdown is carried out by means of a contact 10 and the like in a switch after the auxiliary contact 4 in the last network 3 is opened. COPYRIGHT: (C)1990,JPO | ||||||

| A relay with two current paths thermally connected in parallel is particularly fail-safe. In case of a failure of one main contact, the additional load current is led via the remaining functioning main contact. The failed main contact as well as the thermal connection between the two main contacts then serve as heat sinks, whereby the relay can continue to operate. | ||||||

| A switch apparatus usable in a DC circuit employs a rotatable shaft having conductors that are removably connected with two or more pairs of contacts that are situated on line conductors and load conductors and that are connected in parallel by the conductors on the shaft. In rotating the shaft to open the switch, one pair of the contacts is electrically disconnected prior to electrical disconnection of the other pair of contacts. Further rotation of the shaft causes the other pair of contact to eventually become disconnected. Electrical arcs thus form only at the air gaps between the other pair of contacts and the conductor. Magnetic field elements in the form of permanent magnets are situated in the vicinity of the air gaps of only the other pair of contacts and apply Lorentz forces to the arcs to extinguish them. | ||||||
