Be provided with auxiliary switch in the both sides, front and back of operating mechanism, the main shaft of contact system one and contact system two is provided with the cam driving auxiliary switch.
Preferably, described operating mechanism is realized electric operating by the electromagnet one and electromagnet two driving being positioned at both sides before and after it and/or is realized manual operation by the handle drives be located thereon.
Preferably, above described contact system one and described contact system two, lid is equipped with.
The utility model adopts breaker of plastic casing design principle, and adopt modularized design, its structure is simple, compact, small volume, and insulation is reliable, and better, the specified connection breaking capacity of arc quenching effect is higher, has the performance of shock resistance, vibration.
Accompanying drawing explanation
A kind of two positions change over switch general structure schematic diagram that Fig. 1 provides for the utility model;
A kind of two positions change over switch internal structure schematic diagram that Fig. 2 provides for the utility model;
Fig. 3 is auxiliary switch installation site of the present utility model schematic diagram.
Embodiment
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Composition graphs 1 to Fig. 3, a kind of two positions change over switch that the utility model provides comprises contact system 1 and contact system 27 liang group contact system, and two groups of contact systems are all with arc quenching system 1, and two groups of contact system both sides are placed in pedestal 8 symmetrically.Between two groups of contact systems, bamboo product operating mechanism 6, drives two groups of contact systems respectively by operating mechanism 6.When operating mechanism 6 is in mode of operation for the moment, under the effect of operating mechanism 6, make one group of contact system in two groups of contact systems be in closure state, another group contact system is in open position; When operating mechanism 6 is changed to mode of operation two by mode of operation one, under the effect of operating mechanism 6, the one group of contact system being in closure state disconnects, and the one group of contact system being in off-state closes, thus forms the translation function of change over switch.
Operating mechanism 6 realizes manual operation by handle 4, or realizes electric operating by electromagnet 1, electromagnet 25.Auxiliary switch 9 designs in operating mechanism 6 both sides, the main shaft of contact system designs cam 10 and drives auxiliary switch 9, its action and main contact synchronized movement.Design cover 11 on pedestal 8.The contact of the change over switch that the utility model provides, arc quenching system, the parts such as pedestal adopt the frame mode of breaker of plastic casing, its structure is simple, compact, small volume, alternate mutually insulated, reliable, better, the specified connection breaking capacity of arc quenching effect is higher, has the performance of shock resistance, vibration.
Although the utility model describes with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is only used to the utility model is described; should understand and wherein can make various changes and revise and not depart from the utility model in a broad sense; so be not that conduct is to restriction of the present utility model; as long as in spirit of the present utility model, all the protection range of the utility model claim will be fallen into the change of above-described embodiment, distortion.
