Abstract
The utility model relates to a change-over switch contact system suitable for a change-over switch, comprising two static contacts and a moving contact, which is characterized in that the contact are pushed by a support driven by a cam, enabling the moving contact to be vertical to the static contacts and the support as a half crisscross shape and close or break with the static contacts simultaneously. The contact system has the advantages of more precise breaking, uneasy burnout and long service life.
Description
Affiliated technical field: the utility model relates to a kind of improvement of change over switch contact system, belongs to appliance field.
Background technology:
The contact system of the change over switch that is widely used at present adopts a moving contact (two contacts are arranged), two fixed contacts to form contact system, working method adopts the horizontal direction way of contact for the sound contact system, operating system also adopts the horizontal direction rotation, cause the asynchronous of contact system moving contact and two fixed contact closed and disconnecteds, there is the electric arc that produces when disconnecting in this switch designs mode, make contact cause that easily the contact burns, defective such as product useful life is short.
Summary of the invention:
In order to overcome this defective, the utility model adopts the cam of another contact system way of contact and another kind of structure, make the vertical simultaneously reproduction that vertically can avoid the arc electricity of contact through vanishing, if use direct current, the continuous appearance of electric arc can make voltage decline between current collector and fixed contact, improved reliability of contact, make the resistance of contact minimize contact capacity of improving its and low value being flowed voltage, the situation that the left-right rotation cam can not cause contact one end to burn, improve and connect and breaking capacity long product lifecycle.
The technical scheme that its technical problem that solves the utility model adopts is: the contact system of this product adopts two fixed contacts, a moving contact, and the rotation drive support promotion contact by this product cam makes dynamic/static contact put up with propping up
Shape is while and fixed contact closure or disconnection vertically, thereby reaches the function of product closed and disconnected.
The beneficial effects of the utility model are, in the time of the contact contact system disjunction more accurate, contact is difficult for burning, long product lifecycle.
Description of drawings:
Accompanying drawing is the utility model structure explosive view.
Below in conjunction with drawings and Examples the utility model is further specified.
Among the figure: 1. fixed contact; 2. fixed contact; 3. moving contact; 4. spring; 5. securing member; 6. cam; 7. support
Embodiment:
In the embodiment shown in fig. 1, rotation product cam (6), promote support (7), moving contact (3) is presented down plumbness, fixed contact (1) and fixed contact (2) are parastate, and fixed contact (1), (2) and moving contact (3) contact the turning point contact by face, up to disconnecting simultaneously, otherwise then closed, thereby make the product closed and disconnected.
Claims (2)
1. a change over switch contact system is characterized in that: two fixed contacts of contact system employing, a moving contact.
2. change over switch contact system according to claim 1 is characterized in that: dynamic and static contact is put up with propping up
Shape is vertical.
