The switching device comprises a seesaw key (1), a seesaw armature (2), a pressure spring (3), a movable contacter seesaw piece (5), a support of the seesaw piece (11), still contacter blade terminals (10,11), excitation coils (6,14) and a backing (8); the utility model is characterized in that: the lower part of the seesaw key (1) is provided with the seesaw armature (2), the backing (8) arranged below the seesaw armature (2) is provided with the excitation coil (6,14).

Description

Electromagnetic Drive seesaw type switch device

The utility model relates to a kind of switching device that is used for the control apparatus on/off, especially for electrical equipment (electric light) remote control or control switching device in the electronic switch automatically.

The electronic switch that is used for electrical equipment (electric light) remote control and controls automatically all adopts controllable silicon or relay as switching device.Silicon controlled is anti-interference and anti-overload ability is very poor, is not suitable for controlling perception and capacitive load, has voltage drop to need good heat radiation during work, and poor reliability works long hours and damages easily.And relay when work coil has certain power consumption, and can generate heat is not suitable for working long hours, the contact of relay can not long-term work at overload.Adopt controllable silicon or relay as the electronic switch of switching device, will make controlled electrical equipment no longer controlled once break down, electrical equipment is in long-term energising or off-position is very dangerous.

The purpose of this utility model be to provide a kind of low-power consumption that is used for remote control or controls electronic switch automatically, highly reliable, overload capacity strong, simultaneously can usefulness hand control switch state of switch device.

For achieving the above object, solution of the present utility model is: it comprises, and seesaw button (1), seesaw armature (2), compression spring (3), moving contact are lifted up sheet (5), are lifted up plate rack (11), fixed contact lug plate (10,12), magnetizing coil (6,14) and base (8), it is characterized in that being equipped with under the seesaw button (1) seesaw armature (2) and on the base (8) of seesaw armature (2) below, magnetizing coil (6,14) is housed.

The course of work of the present utility model is: the magnetizing coil of having lifted up the limit when seesaw armature is during by electric pulse, the magnetic force that magnetizing coil produces makes the armature of having lifted up downward by adhesive, drive seesaw button and moving contact are lifted up the direction of having lifted up of sheet and are overturn, make the contact of original closure disconnect then closure of the original contact that disconnects, finish the conversion of an on off state.By manually pushing the limit of having lifted up of seesaw button, can make seesaw button and moving contact lift up the sheet upset equally.

The utility model has the advantages that: switch adopts large-area plane mechanical contact, and operating current is big, reliable, overload capacity is strong, be applicable to various loads.The state self-locking structure of seesaw type makes magnetizing coil adopt pulse signal can realize the upset of on off state, is active in one's movements, reliably.Because only input pulse drive signal when changing on off state, thereby magnetizing coil no temperature rise low in energy consumption, long-term work is safe and reliable.The seesaw type switch structure, even magnetizing coil or circuit break down in the time of can't carrying out switching manipulation by automatically controlled mode, equally can the control switch state with manually pushing the seesaw button.

Now in conjunction with the accompanying drawings the utility model is described in further detail with preferred embodiment

Fig. 1 is the utility model overall structure figure, also is Figure of abstract simultaneously;

Fig. 2 is the three-dimensional position graph of a relation of seesaw button and seesaw armature;

Fig. 3 is that compression spring, moving contact are lifted up sheet, lifted up plate rack, the three-dimensional position graph of a relation of fixed contact lug plate;

Fig. 4 is the magnetizing coil three-dimensional structure diagram;

Referring to Fig. 1, Fig. 2, Fig. 3: the V-shape seesaw armature (2) that two ends are upturned is fixedly mounted on seesaw button (1) below becomes a black box, compression spring (3) is contained in the center pillar chamber (4) of seesaw button, the lower end is enclosed within moving contact and lifts up on the convex shoulder of sheet (18), moving contact is lifted up sheet (5) and is placed on the seesaw support (11), lift up plate rack (11), fixed contact lug plate (10,12) is fixed on the base (8), two magnetizing coils (6,14) use screw (9,13) to be fixed on the below of base (8) two ends seesaw armature (2) respectively.Seesaw button (1) and moving contact are lifted up pressure that sheet (5) and compression spring (3) form and seesaw button (1) and moving contact seesaw are stabilized in respectively swing to state on one side, make the moving contact (20) of closure have certain pressure to protect positive contact with fixed contact (19) simultaneously and contact well.

As shown in Figure 4: magnetizing coil is made of iron core (15,17) and line bag (16), and iron core (15) is simultaneously as the limited post of seesaw button, a bonding in the above rubber blanket (7), and seesaw armature is to the bump and the hot-tempered sound of machinery of iron core when reducing the switch upset.

The utility model also can adopt magnetic material to make seesaw armature (2), make seesaw armature two ends be respectively the S utmost point and the N utmost point, driving pulse to two magnetizing coils (6,14) input different directions, there is a natural attraction between the sexes to make magnetizing coil generation magnetic field and magnetic seesaw armature lift up the limit, repel each other with the adhesive limit same sex, increase the sensitivity and the reliability of Electromagnetic Drive.
