Abstract
The utility model relates to a microswitch, and particularly to a microswitch which is suitable for an automobile and household electrical appliance, particularly a mouse. The microswitch comprises an upper cover and a base. The base is provided with a metal pin I, a metal pin II and a metal pin III. The microswitch further comprises a switching mechanism which comprises a press button, a permanent magnet and a movable sheet. One end of the movable sheet is arranged at the upper end of the metal pin III, and the other end can freely move vertically. The permanent magnet is arranged at the upper end of the metal pin I. The press button is arranged next to and above the movable sheet at the upper end of the metal pin III. The head of the press button is projected from the surface of the upper cover. The microswitch has advantages of small cost, simple structure and long service life. Particularly after high-frequency impact use, normal strength, stroke and hand feel of the press button can be kept unchanged.
Description
Technical field
The utility model relates to appliance switch field, refers in particular to a kind of new construction sensitive switch, is particularly a kind ofly applicable to the sensitive switch that mouse is used.
Background technology
Sensitive switch is to have small contact separation and fast actuation mechanism, the contact mechanism that carries out switch motion by the stroke of regulation and the power of regulation.Because the contact spacing of its switch is smaller, therefore named sensitive switch.
The elastic force of the sensitive switch of prior art has following several mode: spring, metal clips, plastic elastic plate etc.Spring sensitive switch utilizes the bounce of spring to realize switching function.Metal clips sensitive switch utilizes the bounce of sheet metal to realize switching function.Plastic elastic plate sensitive switch is plastic rubber material hot pressing is circular or square salient point, and the bounce by this salient point realizes switching function.The elastic force of above-mentioned three class sensitive switches can reduce gradually along with compression number, and the useful life of button, stroke and feel all can be along with access times change.
Utility model content
Technical problem to be solved in the utility model is to overcome the defect of prior art, provides a kind of and can meet high frequency use needs, simple in structure, the switch of long service life.
The purpose of this utility model can be achieved through the following technical solutions: the sensitive switch of telling comprises metal pin I, metal pin II, metal pin III are installed on upper cover, pedestal, pedestal.Also comprise switching mechanism, described switching mechanism comprises button, permanent magnet, moving plate, and described moving plate one end is arranged on metal pin III upper end, and its other end is provided with contact, and can easy on and off activity.Described permanent magnet is arranged on metal pin I upper end.Described button is arranged near above the moving plate of metal pin III upper end, and head is raised in cap surface.
Described moving plate is conductive ferromagnetics sheet metal.
As the improvement of such scheme, moving plate is connected with metal pin III upper end with brace, because brace has pliability, only plays connection function, therefore very little on the up and down impact of one end of moving plate contact-carrying.Make the electric conductivity of switching mechanism more stable.
Because adopting permanent magnet, sensitive switch of the present utility model can attract ferromagnetics metal principle and lever principle, metal pin I upper end is provided with the permanent magnet that can attract moving plate, moving plate is near being provided with button above metal pin III upper end, when button is subject to pressing force, moving plate has one end meeting moment and the metal pin I upper end of contact to disconnect, and connect with metal pin II upper end, therefore described sensitive switch has the ability of the quick break-make of existing sensitive switch.This function is the attraction of moving plate and lever principle to be realized by permanent magnet, so can not the changing with access times by bond strength, stroke and feel of the utility model sensitive switch.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
Mark in figure: 1 upper cover, 2 pedestals, 3 permanent magnets, 4 moving plates, 5 buttons, 6 braces, 7 metal pin I, 8 metal pin II, 9 metal pin III.
Embodiment
For the ease of the art personnel's understanding, below in conjunction with specific embodiment and accompanying drawing, the utility model structural principle is described in further detail.
As shown in Figure 1, described sensitive switch, comprises upper cover 1, pedestal 2, and metal pin I7, metal pin II8, metal pin III9 are installed on pedestal 2.Also comprise switching mechanism, described switching mechanism comprises button 5, permanent magnet 3, moving plate 4, and described moving plate 4 one end are arranged on metal pin III8 upper end, and its other end energy easy on and off is movable.Described permanent magnet 3 is arranged on metal pin I6 upper end.Described button is arranged near above the moving plate of metal pin III8 upper end, and head is raised in upper cover 1 surface.Moving plate 4 use braces 6 are connected with metal pin III9 upper end, because brace 6 has pliability, only play connection function, thus very little on the up and down impact of moving plate 4 contact-carrying one end, make the electric conductivity of switching mechanism more stable.
When button 5 is subject to pressing force, moving plate 4 has one end meeting moment and the metal pin I7 upper end of contact to disconnect, and connects with metal pin II8 upper end, and therefore described sensitive switch has the ability of the quick break-make of existing sensitive switch.This function is by permanent magnet, the attraction of moving plate and lever principle to be realized.
Claims (3)
1. a sensitive switch, comprise upper cover, pedestal, metal pin I, metal pin II, metal pin III are installed on pedestal, it is characterized in that, also comprise switching mechanism, described switching mechanism comprises button, permanent magnet, moving plate, and described moving plate one end is arranged on metal pin III upper end, and the other end is provided with contact, and energy easy on and off is movable, described permanent magnet is arranged on metal pin I upper end, and described button is arranged near above the moving plate of metal pin III upper end, and head is raised in cap surface.
