Embodiment Construction

[0010] Such as figure 1 As shown, the present invention includes: a control rocker 10, a sealed switch core assembly 5, a controlled rocker 16 inside the sealed switch assembly 5, three connection terminals 6 connected to external circuits, a connection terminal 7, and a connection terminal 15. Its main features are: the control rocker 10 is at the outer end of the sealed switch core assembly, and can rock around the shaft 9, and the control permanent magnet 1 and the control permanent magnet 11 are installed on its two sides. The controlled rocker 16 is inside the sealed switch core assembly 5, and can rock around the axis 8 under the control of the control rocker 10. It has a controlled permanent magnet 2 and a contact 3 at one end, and a controlled permanent magnet at the other end 12 and contact 13. The position of the controlled permanent magnet 2 is corresponding to the control permanent magnet 1, and the magnetic polarity is attracted to the corresponding working surf...

Abstract

The invention provides an anti-explosive rocker switch, consisting of a control rocker, a controlled rocker in a switch core assembly and three terminals. Two ends of the control rocker are provided with control permanent magnets; two ends of the controlled rockers are also provided with controlled permanents and movable contacts respectively; the rocker range of the control rocker is more than the rocker range of the controlled rocker; the magnetic polarity of two permanent magnets at the same side of the control rocker and the controlled rocker are sucking the isomerism correspondingly to the working surface; two rockers are sucked at one pressed end of the control rocker and are separated at the other end thereof; furthermore, one group out of two groups of contacts are turned on and the other group is turned off; the three terminals are respectively connected with corresponding contacts in the switch core assembly and are connected with the external circuits outside the switch core assembly. The switch core assembly is pumped to a vacuum state and where arc distinguish gases or other protection gases are injected and the switch core assembly is sealed, thus protecting the contacts and having the advantages of anti-explosion.

Description

technical field [0001] The invention relates to a switch device, in particular to an explosion-proof rocker switch. It belongs to the field of electrical switches. Background technique [0002] Although the existing rocker switch for breaking the circuit is simple in structure and easy to use, its contacts are not sealed, and the arc generated when switching the circuit communicates with the outside world, so it is not suitable for use in flammable and explosive workplaces. Contents of the invention [0003] The invention aims to solve the shortcomings of the existing switch design, and provides an explosion-proof rocker switch, which puts the switch contacts in the sealed switch core assembly, solves the explosion-proof problem, and is simpler and more reliable in structure. It is suitable for indoor power switch and power switch for other purposes. [0004] The present invention is realized through the following technical proposals. The present invention includes: a co...
