Embodiment Construction

[0021] The action process of the vacuum contact switch of the permanent magnet control among the present invention is: when simultaneously making one of the permanent magnets (3) on the left movable magnet base (11) and the left side on the movable contact support (7) When the permanent magnets (4) are magnetic poles of the same sex, a repulsive force is produced, and the magnet (13) of the movable magnet seat (12) on the right side and the magnet (14) on the right side of the movable contact bracket (7) are magnetic poles of the opposite sex to generate attraction force. Two forces move the movable contact support (7), so that the static and movable contacts (1) (2) are disconnected, and the circuit is disconnected; when the left and right movable magnet seats (11) (12) are made to move permanently When the magnet is switched to the position corresponding to the permanent magnet (4)(14) on the movable contact bracket (7), the magnet poles on the left side between them are of ...

Abstract

A vacuum contact switch controlled by a permanent magnet is a vacuum switch in the switch field of an electric appliance. The vacuum contact switch comprises a casing body (8), a static contact (1), a moving contact (2), a moving contact bracket (7), a moving contact bracket slipper block (6), a slideway (5) of the moving contact bracket slipper block, a vacuum-pumping pipe (9), a sealing cover (10), a magnet (4) at the left side of the moving contact bracket, a magnet (3) on a movable magnet seat on the left side, the movable magnet seat on the left side (11), a magnet (14) at the right sideof the moving contact bracket, a magnet (14) on a movable magnet seat on the right side and the movable magnet seat on the right side (12). The vacuum contact switch combines a vacuum body, the movable magnet seats (11)(12) and operating mechanisms of various electric appliance switches to form a high / low voltage AC / DC electric appliance switch and an explosion prevention switch, through magneticforce which enables the moving and the static contact (2) (1) to be absorbed together or separated apart. The invention has the advantages of multiple contacts, low price, flexible and reliable movement, manual or automatic convenience, small volume and other advantages of vacuum switch.

Description

technical field [0001] The invention relates to an electrical switch, in particular to a vacuum contact switch. Background technique [0002] The contacts of various electrical switches commonly used in the market are all in the air, and arc light will be generated when the contacts make and break the circuit, which is easy to burn out the contacts. The moving contacts of the existing vacuum contact switches are made of The telescopic rubber sleeve is used to help the moving contact and the static contact contact or disconnect, and play a role of sealing. The expansion and contraction of the telescopic rubber sleeve for many times will easily cause the rubber to age and rupture, causing the switch to be scrapped, and the volume is relatively large. Generally, there is only one set of contacts in each vacuum body, and the cost is high. There is also a vacuum switch bulb and a permanent magnet operating mechanism. The vacuum switch bulb is fixed on the switch base. The movabl...
