Description

Rocker switch

Technical field

The utility model relates to a kind of electric switch, particularly a kind of rocker switch that is used for the architectural engineering vibrator.

Background technology

Rocker switch is to use power supply control element very widely, mainly be used in civilian power supply with small capacity switch control, a kind of panel that comprises is disclosed as Chinese patent " rocker switch " (patent No. 94203945.9), pedestal, establish binding post A assembly and binding post B assembly in the pedestal, the panel place establishes a button again, under the button spring and top flat and movable contact spring, it is characterized in that in the groove at binding post A assembly top, establishing a fixing little axle of triangle, put a movable contact spring that is shaped on the U-shaped lug on the top rib of little axle, tooth shape And system one breach is made in the bottom of top flat, rides in the U-shaped lug of movable contact spring, and also is provided with the tapping screw hole on the pedestal.This structure has solved the shortcoming of switch motion sensitivity in the past and switch breaking capacity deficiency, can also effectively prevent the phenomenon that pedestal comes off from panel.But this kind structure exists the problem of a contact and heat accumulation, and is particularly particularly outstanding when load capacity is big, is not suitable for industrial power supply control.

Summary of the invention

The utility model mainly is to solve existing in prior technology: the break-make reliability owes high, forms heat accumulation and the less deficiency of control load capacity easily.

The purpose of this utility model mainly is achieved by following technical proposals: be provided with lever in button, one end links to each other with travel(l)ing rest, the other end links to each other ， And as fulcrum with fixed block, two flat spring sheets are installed in travel(l)ing rest and movable contact spring both sides symmetrically.

As preferably, one end of described lever is an arc surface, have the fixed block socket of chase with a side, the arc surface of the size of chase and lever one end adapts, be recess in the middle of the other end, the mutual socket of ， And that adapts of the recess size of the rod member both sides on its size and the travel(l)ing rest, the center of lever has ellipse hole, and through hole matches with pivot pin on being installed in button; Described movable contact spring is the not convex of back cover, perhaps be suitable for across travel(l)ing rest, can establish other shape of moving contact again at two crossette positions, the two ends of movable contact spring are provided with spring base, the effect one of spring base is to fasten spring leaf, the 2nd, keep the stability of movable contact spring, as long as therefore can reach this function, shape is not limit, and material can adopt plastics or rubber; Described travel(l)ing rest is positioned at below the panel, rod member is arranged at the top of travel(l)ing rest, rod member penetrates panel, its head and an end socket or a snapping that is located at the lever in the button, there is spring groove the both sides of travel(l)ing rest, there is spacer the lower end, and spacer can also can be cross for in-line, and it matches with location notch on the pedestal; Described binding post is positioned at the pedestal bottom plate outside, has three groups, and the fixed contact that is attached thereto penetrates base plate and places base bottom surface ， And to make pedestal be separated to form three independently districts.

The utlity model has following characteristics: simple in structure, contact is reliable, and interrupting performance is good, is specially adapted to the control of industrial electric switch.

Accompanying drawing 1 is the utility model structure chart;

Accompanying drawing 2 is travel(l)ing rest front views of the present utility model;

Accompanying drawing 3 is travel(l)ing rest end views of the present utility model.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail: as shown in the figure, in button 9, be provided with lever 11, one end of lever 11 is an arc surface, have the fixed block 14 socket And of chase as fulcrum with a side, have recess in the middle of the other end, have the head socket of recess with the rod member both sides on the travel(l)ing rest 5, two flat spring sheets 13 are installed between the spring base 6 at the spring groove 4 of travel(l)ing rest 5 both sides and movable contact spring two ends symmetrically, cushion block are arranged below the spring base 6; Described travel(l)ing rest 5 is positioned at below the panel 9, and the rod member 18 on top penetrates panel 7 and socket-connects with lever 11, and it can install three groups of movable contact springs and spring leaf simultaneously, and there is spacer 16 lower end, and its spacer matches with location notch on the pedestal 17; Described movable contact spring 15 is the not convex of back cover; Binding post 1 has three groups, be positioned at pedestal 17 plate outer sides, also have three groups with the fixed contact 2 that binding post 1 links to each other respectively, the base plate that penetrates pedestal 17 respectively enters its interior And pedestal 17 is divided into three separate districts, and the moving contact that adapts with it also is divided into three groups.

As shown in the figure be off state, this moment, moving contact 3 and fixed contact 2 were separated from each other; When external force acts on button 9 and indicates " | " side, because the effect of lever 11, travel(l)ing rest 5 upwards promotes, and rises thereby drive coupled spring one end, when it rises to position above the other end, spring 13 pressure discharge suddenly, up push up thereby promote movable contact spring 15,, rely on the effect of spring force until closed fully with fixed contact, kept moving contact 3 closely to contact circuit turn-on with fixed contact 2; When external force acted on button 9 and indicates " 0 " side, leverage made travel(l)ing rest 5 to lower slider, and under the spring force effect, movable contact spring 15 is return, and moving contact 3 is separated with fixed contact 2, and circuit disconnects, and so forth circulation.

Another embodiment: indicate between the boss of " | " side and the panel 7 at button 9 and to establish a stage clip, at this moment, rely on the effect of spring force, make switch be in off state automatically, have only outside that masterpiece is used for just making circuit turn-on when button 9 indicates " 0 " side, this rocker switch has the auto-cutout function.
