Description
Technical field
This utility model relates to rotary switch field, particularly to a kind of rotary switch.
Background technology
Rotary switch is to control a kind of switch of main contacts break-make with rotary handle.The knot of rotary switch
Configuration formula has two kinds, is one pole unit structure and the many bit architectures of multipole respectively.One pole unit rotary switch
Often it is used in conjunction with rotary shaft potentiometer in the application, and multipole Multi-position rotation switch is used for work shape
The switching of state circuit.
Rotary switch can be used to replace the rotary pulsed generation of traditional resistive potentiometer analog functuion
Device, these rotary switches are typically used in instrument front console and the man machine interface of audio-visual panel, rotation
Turning on pass uses orthogonal optical encoder alternatively to simulate potentiometric pure digi-tal device.
Rotary switch structure in the market is complicated, easy to wear, and stability is not enough, and contact is bad,
Be inconvenient to use.
Utility model content
In order to overcome deficiency described above, the purpose of this utility model be to provide a kind of simple in construction,
Good stability, the rotary switch that contact is good, safe and reliable.
The technical scheme in the invention for solving the technical problem is:
A kind of rotary switch, wherein, including pedestal, axle sleeve, rotating shaft, handle and cover plate, described axle
Set is fixedly connected on described pedestal, and one end of described rotating shaft is socketed in described axle sleeve, described rotating shaft
The other end be connected with described handle, described handle is provided with Handle axis, described cover plate is provided with
Through hole, described Handle axis is socketed in described through hole, and described handle is provided with contact rod, described lid
Being provided with breach on plate, the edge of described cover plate is provided with public terminal and gear terminal.
As a kind of improvement of the present utility model, between described rotating shaft and described handle, it is provided with torsion spring.
As further improvement of the utility model, between described handle and described cover plate, it is provided with bullet
Spring.
Further improve as of the present utility model, described cover plate is additionally provided with crawl terminal.
In this utility model, turning handle, Handle axis rotates on cover plate inner via hole, on handle
Contact rod can be with public terminal or gear termination contact, and Handle axis can be carried out by the breach on cover plate
Spacing, thereby may be ensured that contact rod is stable with public terminal or gear termination contact；This utility model
Simple in construction, good stability, contact is good, safe and reliable.
Accompanying drawing explanation
For ease of explanation, this utility model is made by following preferred embodiment and accompanying drawing to retouch in detail
State.
Fig. 1 is structural representation of the present utility model；
Reference: 1-pedestal, 2-axle sleeve, 3-rotating shaft, 31-torsion spring, 4-handle, 41-Handle axis,
42-contact rod, 43-spring, 5-cover plate, 51-through hole, 52-breach, 53-public terminal, 54-keeps off
Position terminal, 55-crawl terminal.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with
Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched
The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, a kind of rotary switch of the present utility model include pedestal 1, axle sleeve 2, rotating shaft 3,
Handle 4 and cover plate 5.
Axle sleeve 2 is fixedly connected on pedestal 1, and one end of rotating shaft 3 is socketed in axle sleeve 2, rotating shaft 3
The other end be connected with handle 4.
Being provided with Handle axis 41 on handle 4, cover plate 5 is provided with through hole 51, Handle axis 41 is socketed
In through hole 51.
It is provided with contact rod 42 on handle 4, cover plate 5 is provided with breach 52, the edge of cover plate 5
It is provided with public terminal 53 and gear terminal 54.
In this utility model, turning handle 4, Handle axis 41 rotates on cover plate 5 inner via hole 51,
Contact rod 42 on handle 4 can contact with public terminal 53 and gear terminal 54, on cover plate 5
Breach 52 can Handle axis 41 be carried out spacing, thereby may be ensured that contact rod 42 and common port
Son 53 or gear terminal 54 contact are stable.
Further, between rotating shaft 3 and handle 4, it is provided with torsion spring 31, can preferably make handle 4
Rotary motion, when also making handle 4 rotate in rotating shaft 3, can carry out spacing and multiple with torsion spring 31
Position.
Further, between handle 4 and cover plate 5, it is provided with spring 43, can preferably make Handle axis
4 turn over public terminal 53 or gear terminal 54, will not block.
In this utility model, in order to make handle 4 when quitting work, safer, on cover plate 5
Being additionally provided with crawl terminal 55, when handle 4 does not works, contact rod 42 contacts with crawl terminal 55.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality
Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle
Deng, within should be included in protection domain of the present utility model.
