Description
Technical field
The present invention relates to a kind of switching device that is used for on-off circuit, relate in particular to a kind of mains switch of dial type.
Background technology
Traditional tumble power switch as shown in Figure 1, comprise: pedestal 1, be arranged on the center terminal 4 and the fixed terminal 3 of pedestal 1 base plate, be horizontally set on the movable contact spring 6 above the center terminal 4, be arranged on the moving contact 7 of movable contact spring 6 ends, and be arranged on fixed terminal 3 surface and with moving contact 7 corresponding fixed contacts 5, pedestal 1 upper oral part is provided with toggle 2, offer the spring eye 21 that Open Side Down in the toggle 2, be provided with spring 9 and sliding pin 20 in the spring eye 21, the surface of the external part of sliding pin 20 and movable contact spring 6 offsets.When stirring the toggle 2 of this mains switch, toggle 2 drives movable contact springs 6 by spring 9 and sliding pin 20 and rotates around center terminal 4, make produce between moving contact 7 and the fixed contact 5 in conjunction with or the action that separates, thereby circuit is switched on or switched off.When this tumble power switch used, 4 of movable contact spring 6 and center terminals can produce tiny displacement, make to have the tiny displacement and the sassafras that rubs between dynamic and static contact, even shake, their combinations are slow in one's movements when separating, and cause between contact and strike sparks, more serious electric arc occurs, shortened switch life; Also have when sliding pin 20 moves near center terminal 4 position of the fulcrum, according to mechanical analysis, it is very little that dynamic and static contact presses power indirectly, makes switch produce the unreliable phenomenon of " seemingly contacting noncontact; seemingly disconnect non-disconnection ", thereby also can influence switch safe handling and life-span.
Summary of the invention
The object of the present invention is to provide a kind of dependability height, and the tumble power switch that is difficult for breaking down.
Further purpose of the present invention is to provide the more convenient reliable tumble power switch that is rotationally connected between a kind of movable contact spring and the toggle.
For realizing purpose of the present invention, a kind of tumble power switch, comprise pedestal and toggle, be arranged on fixed terminal and center terminal on the pedestal bottom plate, the fixed terminal surface that is positioned at pedestal is provided with fixed contact, center terminal is provided with movable contact spring, movable contact spring is provided with and the corresponding moving contact of fixed contact, the bending that described center terminal is L-shaped, the center terminal upper surface that is positioned at pedestal offers location notch, the bottom of movable contact spring is arranged in the location notch of center terminal, and pedestal is provided with cover plate, and the oral area of cover plate is provided with toggle, offer the spring eye that Open Side Down in the toggle, spring is arranged in the spring eye, and the lower end of spring and the upper end of movable contact spring are rotationally connected mutually, the fixed contact on the fixed terminal be arranged on movable contact spring one side and with the corresponding position of moving contact on.
For realizing further purpose of the present invention, a kind of tumble power switch, also comprise: described toggle spring eye exit is provided with a pair of limited bayonet, the upper end of movable contact spring is provided with a pair of and the convex shoulder limited bayonet corresponding matching, and movable contact spring cooperates rotation to be arranged on the bottom of button and closely offsets with the upper end of spring by convex shoulder and limited bayonet;
Described base bottom also is provided with a pair of block that is respectively in center terminal location notch both sides.
The invention has the beneficial effects as follows: with movable contact spring one end is fulcrum, in motion process, only exist between movable contact spring and center terminal and relatively rotate, with respect to conventional switch, the speed of movable contact spring action is very quick, and before button drives the movable contact spring action, acts between the dynamic and static contact from the pressure of spring always, make the switch contact very stable, reduce the generation of electric arc so effectively, improved the ability that the anti-high seas of switch are gushed electric current, the life-span of having improved switch.
