Abstract
The invention provides a dual-position converting switch. The dual-position converting switch is characterized by comprising an operation mechanism, wherein the operation mechanism respectively controls two groups of symmetrical contact systems; each contact system comprises a connecting rod; one end of the connecting rod is connected with the operation mechanism, and the other end of the connecting rod is connected with a movable contact through a rotating shaft; and the movable contact rotates around the rotating shaft under the control of the operation mechanism. The dual-position converting switch provided by the invention utilizes a plastic-shell breaker design principle and a modularized design and thus has the advantages of simple and compact structure, small volume, reliable insulation, good arc extinguishing effect, high rated switching-on or switching-off capacity, and shock resistance and vibration resistance properties.
Description
Technical field
The present invention relates to a kind of low pressure two positions change over switch, belong to the low-voltage circuit breaker design field.
Background technology
The function of change over switch with manual or electronic mode connect, disjunction and change-over circuit (power supply or load), and cooperate control and the protective device of forming various uses with suitable control and protective circuit.The shortcoming of change over switch is at present: complex structure, volume is bigger.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure and change over switch that volume is less.
In order to achieve the above object; Technical scheme of the present invention has provided a kind of two positions change over switch, it is characterized in that: comprise operating mechanism, operating mechanism is controlled the contact system of two groups of symmetries respectively; Contact system comprises connecting rod; One end attended operation mechanism of connecting rod, the other end connects moving contact through rotating shaft, and moving contact is rotation around the shaft under the control of operating mechanism.
Preferably, said operating mechanism or manual actuation, or by electromagnet and motor-driven.
The present invention adopts the breaker of plastic casing design principle, adopts modularized design, and it is simple in structure, compact, volume is less, and insulation is reliable, and better, the specified connection breaking capacity of arc quenching effect is higher, has the performance of shock resistance, vibration.
Description of drawings
Fig. 1 is the sketch map of a kind of two positions change over switch provided by the invention.
Embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1, for a kind of two positions change over switch provided by the invention, comprise operating mechanism 4, operating mechanism 4 is controlled the contact system of two groups of symmetries respectively.The contact system that is positioned at the left side comprises first connecting rod 3, an end attended operation mechanism 4 of first connecting rod 3, and the other end connects the rotation around the shaft under the control of operating mechanism 4 of first moving contact, 2, the first moving contacts 2 through rotating shaft.The contact system that is positioned at the right side comprises second connecting rod 5, an end attended operation mechanism 4 of second connecting rod 5, and the other end connects the rotation around the shaft under the control of operating mechanism 4 of second moving contact, 6, the second moving contacts 6 through rotating shaft.
The two positions of change over switch is respectively " I " position and " II " position, and operating mechanism 4 is controlled two groups of contact systems respectively.When operating mechanism is in " I " position, I power connection, the disjunction of II power supply; When change over switch is in " II " position, the disjunction of I power supply, II power connection.Shown position is that change over switch is in " I " position, when operating mechanism 4 by " I " position to " II " position, drive second connecting rod 5 and make second moving contact 6 do clockwise motion around the shaft with O2, make second moving contact 6 and second fixed contact, 7 closures like this; The first connecting rod 3 of operating mechanism driving simultaneously makes first moving contact 2 do motion clockwise around the shaft, and first moving contact 2 and first fixed contact 1 are broken off, and so just accomplishes the transfer process of change over switch.Otherwise step is opposite.
Claims (2)
1. two positions change over switch; It is characterized in that: comprise operating mechanism (4); Operating mechanism (4) is controlled the contact system of two groups of symmetries respectively, and contact system comprises connecting rod, an end attended operation mechanism (4) of connecting rod; The other end connects moving contact through rotating shaft, and moving contact is rotation around the shaft under the control of operating mechanism (4).
2. a kind of two positions change over switch as claimed in claim 1 is characterized in that: said operating mechanism (4) or manual actuation, or by electromagnet and motor-driven.
