を受けて、貯留室（タ）内のガス圧カを上昇させる。Next, we will explain the operation of this conventional device. When this switch is in the closed state, current flows from the first terminal plate (C) to the fixed contact (C), and from the movable contact (3) to the current collector (DA). When the flow is to the second terminal plate (jl) through the movable contact (3), when the movable contact (.71) is driven in the direction of the arrow by a drive mechanism (not shown), the movable contact (3) 2
) and an arc (/O) is generated between both contacts. On the other hand, the annular magnet (ff+ is magnetized in the axial direction,
At the storage chamber entrance (?a”), magnetic flux (φ) including a radial component
occurs. The arc (l0) receives a force in the circumferential direction due to this magnetic flux (φ). By becoming a rotating arc and elongated in the radial direction, the gas heating effect by the arc (/0) increases the gas pressure in the storage chamber (ta).

における消弧を補助するものである。In addition, as the piston (/) moves in the cylinder (//) along with the movable contact (3) in the direction of arrow A,
The pressure inside the negative pressure chamber (/J) is detected as a negative pressure, which prevents the gas pressure from rising when a small current is interrupted (9).
This supplements the outflow of insulating arc-extinguishing gas from the insulating arc-extinguishing gas and assists in arc-extinguishing when a small current is interrupted.

な消弧効来が得られないという問題点を有している。However, in conventional switches such as those mentioned above, the gas heating effect due to the arc is small in case of small current interruption.
Therefore, the increase in gas pressure in the storage chamber (fl) is small.Also, since the first contact made of finger contacts has a plurality of grooves in the axial direction from the tip, the magnet Due to the magnetic field (φ) created by the arc (/0) on the first contact C), the foot of the arc (/0) moves <<, so the arc (
Since the gas flow is weak relative to the foot of /0), there is a problem that a sufficient arc extinguishing effect cannot be obtained.

る。Since the arc contact in this invention has no grooves in the circumferential direction, the legs of the arc move due to the driving force in the circumferential direction caused by the generated arc and the cross magnetic field near the arc contact created by the magnet. Therefore, there is a flow of insulating arc extinguishing gas relative to the arc foot on the arc contact, and as a result, the arc foot is cooled and the arc extinguishing ability is reduced. [Embodiment] The present invention will be explained below based on the drawings showing the embodiment. In Fig. 1 showing the first embodiment, reference numbers (71 to
) is the same as the conventional device, and the symbol (2l) is electrically connected at the fixed side end of the fixed contact (2). This is a cylindrical arc contact provided on the outer periphery.The operation of this first actual switch will be explained below.When the movable welder (3) is opened from the fixed contact (.21), An arc (/0) is generated between the two welding fuses f21131.

とができ．充分な消弧能力が得られる。On the other hand, magnet f. rl is magnetized in the axial direction ((). At the tip of the arc contact (2/), a magnetic flux (φ) with a radial component is generated. This magnetic flux (φ) causes the magnetic flux (φ) on the arc contact (Y/) to The legs of the arc (/O) rotate under force in the circumferential direction. As a result, the legs of the arc (/O) on the arc contact (ko/) rotate.
), a relative insulating arc-extinguishing gas airflow is generated, and the legs of the arc (/0) are cooled. Arc extinguishing ability can be increased. Sufficient arc extinguishing ability can be obtained.

There are boron-based magnets, but magnets with strong magnetic force have a greater arc-extinguishing effect.

It is better to use an arc-resistant material such as tungsten or carbon.
