Specific implementation mode
In order to make those skilled in the art be better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings to this
The technical solution of utility model is further elaborated.
Embodiment one：It is a kind of novel switched as shown in Fig. 1 ~ 3, including switch case, the pedestal that is connect with switch case with
And the button in switch case, the sealing ring passed through for button is installed, pedestal is equipped with normally open end in switch case
Sub, normally closed terminal and common terminal, wherein between normally opened terminal and normally closed terminal, normally closed terminal is all provided between of go side together
There are resistance, the junction of the resistance and each terminal plastic in pedestal.
Resistance both ends riveting in the present embodiment has copper sheathing, and copper sheathing is L-shaped and conductive, one end riveting of copper sheathing
On resistance, the other end is welded on each terminal, and the setting of copper sheathing can effectively avoid resistance from directly being welded with terminal stress,
It plays a protective role to resistance, while but also connection between resistance and terminal is more firm, certainly, resistance, resistance both ends
Copper sheathing and copper sheathing and each terminal junction it is plastic in pedestal.
Normally opened terminal, normally closed terminal and common terminal are respectively equipped with contact area, and pedestal is equipped with movable contact spring, movable contact spring packet
Fixing end and free end are included, fixing end is fixed on common terminal, and free end is located at below button, and go side connects movable contact spring together
Tactile region contacts always, and when specifically used, button is pressed, and free end moves downward, and makes movable contact spring and normally opened terminal contact zone
Domain contacts, and realizes switching function conversion.
As a preferred embodiment, set on movable contact spring there are two contact surface, a contact surface in a free state with it is normally closed
Terminal contact region contacts, and another contact surface is located above normally opened terminal contact region in a free state, i.e., when button is pressed,
Free end moves downward, and the contact surface contacted with normally closed terminal contact region leaves normally closed terminal contact region, at the same time position
Contact surface above normally opened terminal contact region moves downward, and realizes switching function conversion.
In an assembling process, first movable contact spring is assembled on pedestal, is reloaded into switch case, therefore can intuitively seen
To state of the movable contact spring on pedestal, it is ensured that movable contact spring contact is reliable, and in use, stress concentration four contact surface positions,
So that the wear extent of movable contact spring is small, service life is high.
Embodiment two：As shown in Figure 4,5, the present embodiment is similar with embodiment one, the difference is that on the movable contact spring
Equipped with contact surface, contact surface is contacted with normally closed terminal contact region in a free state, i.e., on the movable contact spring in the present embodiment only
If there are one contact surface, contact surface is contacted with normally closed terminal contact region in a free state, when button is pressed, contact surface from
It opens normally closed terminal contact region to move to normally opened terminal contact region, and is finally contacted with normally opened terminal contact region.
In order to improve the reset dynamics of switch, the present embodiment is equipped with mounting post on the position that pedestal corresponding button is installed,
Mounting post is equipped with spring, and the free end lower surface of movable contact spring is equipped with protrusion, and protrusion is mounted in spring so that movable contact spring is not
It is also easy to produce displacement, is avoided using failure, in specific implementation process, when button pressed downwards, movable contact spring compressed spring is driven, waits pushing
After power removes, under the action of spring own resilient, make movable contact spring and button Rapid reset.
Fig. 6 is a kind of circuit connection diagram of the present embodiment, wherein COM is common terminal, and NO is normally closed terminal, and NC is normal
Beginning, is connected between resistance R1, normally closed terminal and normally opened terminal between common terminal and normally closed terminal and is connected with resistance
R2, in a free state, common terminal and normally closed terminal form a closed circuit, when button is pressed, common terminal with often
Beginning forms a closed circuit, it should be noted that the present embodiment is not restricted to the circuit connection diagram relationship of Fig. 6, tool
Body can make corresponding change according to customer demand to circuit connecting relation.
Finally, it should be noted that above example is only to illustrate the technical solution of the utility model rather than to this reality
