Technical problem to be solved in the utility model is: a kind of toggle switch that can reduce or prevent to produce electric arc in the switch use is provided.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of toggle switch, comprise pedestal, be arranged at least one pair of terminal of base bottom, be arranged on each to the movable contact spring on the terminal, be arranged on the moving contact of movable contact spring one end, be arranged on a terminal top and with the corresponding fixed contact of moving contact, be arranged on the toggle of pedestal upper oral part, and be arranged on spring in the toggle lower springs chamber, the other end of described movable contact spring is provided with spring base, the bottom of spring is arranged in the spring base, the both sides of spring base bottom surface are provided with a pair of guide ledges, its side is provided with a pair of positioning boss, guide ledges of the same side and positioning boss are formed gathering sill respectively, are respectively arranged with guide pad with the corresponding pedestal of two gathering sills both sides, and movable contact spring is by being equipped with on the another terminal of base bottom between gathering sill and the guide pad.

Spring base on the described movable contact spring is " U " structure, should " U " structure comprise the madial wall that joins with movable contact spring, bottom surface and by bottom surface and the madial wall lateral wall that fuses, also be respectively arranged with the protective plate of a pair of inside bending in the both sides of lateral wall, described guide ledges is arranged on the both sides of bottom surface, and positioning boss is arranged on the both sides of madial wall.

The beneficial effects of the utility model are: this construction of switch is simple, safe and reliable, can shorten the folding time between the dynamic and static contact during use, therefore, can effectively avoid the generation of electric arc between the switch contact, prolong the useful life of switch, compare with conventional switch, can bear bigger surge current, the scope of application is more extensive.

Embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.

Extremely shown in Figure 6 as Fig. 3, toggle switch described in the utility model, a kind of toggle switch, comprise pedestal 1, be arranged at least one pair of terminal 2 and the terminal 3 of pedestal 1 bottom, be arranged on each to the movable contact spring 5 on terminal 2 and the terminal 3, be arranged on the moving contact 6 of movable contact spring 5 one ends, be arranged on a terminal 3 tops and with moving contact 6 corresponding fixed contacts 4, be arranged on the toggle 9 of pedestal 1 upper oral part, toggle 9 is installed in the place suitable for reading of pedestal 1 by pin 10, and be arranged on spring 8 in the toggle 9 lower springs chambeies, the other end of movable contact spring 5 is provided with spring base 51, and the bottom of spring 8 is arranged in the spring base 51, and the both sides of spring base 51 bottom surfaces are provided with a pair of guide ledges 52, its side is provided with a pair of positioning boss 53, the guide ledges 52 and the positioning boss 53 of the same side are formed gathering sill 54 respectively, are respectively arranged with guide pad 7 with two gathering sills, 54 corresponding pedestals, 1 both sides, and movable contact spring 5 is by being equipped with on the another terminal 2 of pedestal 1 bottom between gathering sill 54 and the guide pad 7.

Spring base 51 on the described movable contact spring 5 is " U " structure, should " U " structure comprise the madial wall that joins with movable contact spring 5, bottom surface, and by bottom surface and the madial wall lateral wall that fuses, also be respectively arranged with the protective plate 511 of a pair of inside bending in the both sides of lateral wall, described guide ledges 52 is arranged on the both sides of bottom surface, and positioning boss 53 is arranged on the both sides of madial wall.

The course of work of the present utility model is: when pressing toggle 9 left, toggle 9 rotates counterclockwise around pin 10, in toggle 9 rotation processes, be arranged on the constantly distortion and deformation takes place of spring 8 in the spring cavity of toggle 9 bottoms, when 9 groups of toggles to the left the time, spring 8 also overturns because of being deflected into the limit, make movable contact spring 5 rotate counterclockwise with cooperatively interacting of guide pad 7 by location notch 52 on its spring base 51 and the location notch between the guide ledges 53 54, that is: positioning boss 52 inclines slide fast along the upright side of guide pad 7, meanwhile, guide ledges 53 is also slided fast along the guiding surface of guide pad, moving contact 6 on the movable contact spring 5 and fixed contact 4 quick-makes on the terminal 3 are connected switch fast; Press toggle 9 to the right switch is turn-offed rapidly, its process is identical with the connection process, repeats no more here.

The utility model improves by the set-up mode to movable contact spring 5 and spring 8, shortened the time of contact between the dynamic and

static contact

6 and 4 in the switching process greatly, thereby eliminated the shake of movable contact spring 5 in switching process, avoided between dynamic and

static contact

6 and 4, producing electric arc, thereby also just avoided the dynamic and static contact 6 of arc erosion and 4.Like this, not only prolonged the useful life of toggle switch, and compared with traditional toggle switch of same size, toggle switch described in the utility model can bear bigger surge current, thereby has widened its application scenario.
