Under Fig. 3-5 and remote control switch state shown in Figure 6, pin 16 is arranged in the point 24 of heart-shaped chute 15.Remote control switch contact separation shown in Figure 3 is disconnected, because armature contact is lifted away from fixed contact 1.

If magnetic is encouraged coil 9 and accepted voltage in this case, then slide block 7 moves down (with the relevant position display in remote control switch shown in Figure 3 position).In this motion process, pin 16 is at first through point 24 that extends moving direction 14 and the right line part 25 of following process chute 15.The bend 26 that links to each other with this line part 25 moves on in the v-shaped structure portion 27 pin 26, and here, pin is shown in the solid line of Fig. 6.In the process process of chute 15 of pin 16, wait armed lever 17 to rotate (arriving bends 26) earlier slightly along clockwise direction and also rotate counterclockwise subsequently up to pin 16.

If magnetic is encouraged coil 9 no-voltages, then back-moving spring 20 is upwards pressed slide block 7.V-shaped structure portion 27 shifts to pin 16 simultaneously, is pasting structural portion 27 (seeing the position of the pin 16 shown in the dotted line) up to it.Therefore, slide block 7 not calamity returns position shown in Figure 3, but remains on the position shown in Figure 8, and on this position, the armature contact 2 of contact separation shown in Fig. 3,8 is still pasting fixed contact 1 and this contact separation thereby joint.Therefore, even if being a magnetic, the second switch position encourages the position of the switch that coil 9 no-voltages also can keep (stablizing).

The motion that slide block 7 returns the position of the switch shown in Figure 3 can put on the potential pulse that magnetic encourages on the coil 9 by another and realize, be that slide block 7 moves down again by another such potential pulse, thus one, pin 16 moves in the bend 28 of heart-shaped chute 15 left wings (seeing the chain-dotted line of the pin 16 among Fig. 6).After potential pulse disappeared, back-moving spring 20 can make on the slide block 7 and move, and here, pin 16 returns in chute 15 points 25 by left line part 29.Now, slide block 7 can move into the position of the switch shown in Figure 3 again, and on this position, contact separation shown in Figure 3 disconnects.

Different with present form of implementation, but also manual operation of remote control switch of the present invention, and for this reason, slide block 7 is equipped with an operating knob 36 that passes drain pan 23 breach as described above.But, the function of the locking mechanism that is made of pin 16 and chute 15 is just the same in manually slider-operated.

In order pin 16 to be taked pass through counterclockwise the above-mentioned route of chute 15, stipulate following two measures, at first, be provided with a spring 30, it is towards armed levers 17 such as chute 15 left wings ground pretension.In this specification and follow-up claims, " chute 15 wings " are meant by a

line part

25 or 29 and the integral body that constitutes of the

bend

26,28 that is attached thereto.For example be understood that towards armed levers 17 such as chute left wing pretension, this with towards armed levers 17 such as chute right flank pretension effect same is arranged, wherein chute 15 must be designed to certainly relatively that it is the mirror image symmetry along axis that moving direction 14 extends.

In the preferred implementing form of accompanying drawing, spring 30 is designed to the form of helical compression spring, its end bearing on drain pan 23 inwalls and the other end be bearing in etc. on the armed lever 17.In order stably to settle spring 30, similarly can offer bolt shape forming section 37 on armed lever 17 and the drain pan 23 waiting with back-moving spring 20, spring 30 ends are with regard to sleeve thereon.

Spring 30 power on the armed lever 17 such as is applied to and has guaranteed to sell 16 and always be pressed towards chute 15 left wings and thereby be in on the position shown in the continuous chain-dotted line.

(pressing to chute 15 left wings waiting armed lever 17) when spring function can be realized by alternate manner, also is feasible without the scheme of spring 30.This for example can realize so that squint is to chute left wing slightly promptly to wait armed lever 17, and like this, chute left wing is shifted to by gravity in armed lever 17 ends of waiting that have pin 16.

For anti-shotpin 16 enters left line part 29 after leaving point 24, in line part 29 bottoms, be provided with one domaticly 31, it originates in the zone that links to each other with bend 28 and towards the rising of sharp 24 ground.Domatic 31 terminal points are edges 33, and this edge and the v-shaped structure portion 27 justified margin ground in line part 25 zones extend.Pin 16 root leave at sharp 24 o'clock along the edge 33 slide and thereby can not enter in the left line part 29, but must move into right line part 25 along v-shaped structure portion 27 edges.

If Deng armed lever 17 towards the chute right flank be tightened up, then above-mentioned domatic 31 must be arranged in the right line part 25 of chute 15.

The replacement organization plan of a heart-shaped chute 15 that also can be susceptible to is that they are symmetrical fully, i.e. the complete symmetrical (see figure 9) of left and right sides both wings.Here, pin 16 contacts the intersection point 34 of v-shaped structure portions 27 and changes right line part 25 or left line part 29 subsequently randomly over to after leaving point 24.After pin 16

left bend

26 or 28, it was encouraged potential pulse on the coil 9 back that disappears and arrives position shown in the dotted line below intersection point 35 putting on magnetic.When slide block 7 was mobile once more, pin 16 contact intersection points 35 also entered right bend 26 or left bend 28 again at random.In both cases, pin 16 finally returns point 24.

From description to chute 15 functions, we can know, chute also can become the shape of non-heart, and it also can stably be bearing on the holding point of two spaces in non-heart-shaped structure and chute 15 can make pin 16 frictions move between two holding points littlely.For example, can be susceptible to such measure according to the form of implementation of Fig. 9, promptly 15 one-tenth half of chutes are heart-shaped, promptly have only one of them wing.

According to another variant embodiment that can be susceptible to, the shape of the wing can be different from half heart, but can become half elliptic.

Therefore, the present invention is not limited to and roughly becomes heart-shaped chute 15 structures in shown in the drawings the extorting a confession.

Remote control switch of the present invention can be designed to include many arbitrarily contact separations, wherein only shows the remote control switch that comprises two contact separations in the accompanying drawings.In Fig. 1-3, only show a contact separation respectively, it is arranged between the middle case 21 of remote control switch shell and the top shell in the zone.Second contact separation between middle case 21 and drain pan 23 and its aufbauprinciple the same with first contact separation shown in Fig. 1-3.

Can stipulate that second contact separation is configured to have the function that is different from first contact separation.This is meant, when first contact switch has closure function (contact separation disconnects on first position of the switch shown in Fig. 1-3 and closure on second switch position shown in Figure 8), second contact separation has been configured to break function, and (Fig. 8) disconnects on the second switch position thereby it is closed on first position of the switch (Fig. 1-3).

But, the function of these two contact separations be can choose wantonly or combination in any.Therefore, for example these two contact separations can be designed to normally opened contact or normally-closed contact, perhaps one of them be designed to or two all be designed to alternate contact.

Magnet arrangement 8 and slide block 7 are provided for this two contact separations jointly, and promptly the armature contact 2 of these two contact separations is placed on the unique common slide block 7 and can moves by these slide block 7 relative fixed contacts 1.As shown in Figure 4, slide block 7 has two

arms

41,42 that separate by a seam 40 in armature contact 2 zones.On two

arms

41,42, the armature contact bridge 2 of remote control switch is installed,, unique armature contact 2 or two armature contacts 2 of each contact separation are housed here on each arm 41,42.In the remote control switch shell that assembles, the wall 45 of middle case 21 is positioned at the zone of seam 40.Therefore, each

arm

41,42 stretches in its affiliated contact separation and in armature contact 2 zones and separates with another contact separation by the wall 45 of middle case 21.

Characteristics that are arranged on the slide block 7 in the remote control switch of the present invention are that whole the first arm 41 is designed to and all the other slide blocks 7 separated parts, but can be fixed on all the other slide blocks 7.This stationarity can realize that in principle for example arm 41 can be bonded on all the other slide blocks 7 by any way.

Preferred implementing form with reference to the accompanying drawings, stipulated with arm 41 releasably and form fit be fixed on structure on the slide block 7.For this reason, in the first arm 41, be processed with dovetail groove 43 one.Want therein to form a guide frame 44 in all the other slide block 7 zones of fixed arm 41, its shape of cross section is consistent but smaller with the shape of cross section of groove 43.Arm 41 can be installed on this guide frame 44 and thereby can by form fit be fixed on all the other slide blocks 7.

The shape of cross section of groove 43 and guide frame 44 can be choose wantonly and for example be as shown in the figure capitate.As the replacement mode, groove 43 and guide frame 44 can have trapezoidal cross-section, here, trapezoidal be parallel to each other must be arranged in the corresponding with it face of structure 44 or the bottom of groove 43 than long side, to realize that arm 41 is connected with the form fit of all the other slide blocks 7.

As shown in Figure 7, during remote control switch, at first slide block 7 is loaded in the drain pan 23 in assembling, then, middle case 21 loaded onto and subsequently holding arms 41 install on all the other slide blocks 7.Therefore, can avoid

slider arm

41,42 being penetrated in zone between drain pan 23 and the middle case 21 or between top shell and middle case 21 arduously.

In order can be simply slide block 7 to be packed in the remote control switch shell, can differently stipulate following measure with above explanation, promptly do not make whole arm 41, but only have the bottom of armature contact 2 to be designed to be independent of the parts of all the other slide blocks 7 its a part of immediate shipment.In addition, another part of arm 41 is designed to be integral with slide block 7.But be noted that the top that still ends at wall 45 with slide block 7 all-in-one-piece arms when slide block 7 is positioned on first position of the switch (Fig. 3) simultaneously, so as assembling will middle case 21 during remote control switch wall 45 penetrate in the seam 40 between two

arms

41,42.

Another aspect of the present invention is that armature contact 2 is remained on structural design scheme on the slide block 7.As shown in Figure 6, for the armature contact 2 that keeps a contact separation, slide block 7 has a cage 50.Because remote control switch shown in the drawings comprises two contact separations, its armature contact 2 is placed on two

arms

41,42 as described above, so each arm 41, pairs setting system have such cage 50.

Cage 50 has two

sidewalls

51,52 that extend and the

cover plate

53,54 that connects them on slide block 7 moving directions 14.This armature contact 2 (seeing Fig. 1,2) or two armature contact (see figure 3)s are installed on the plate 6 that roughly becomes rectangle, and described plate 6 is placed between cage 50 sidewalls 51,52.Look also has a stage clip 55 in cage 50, and it presses to cover

plate

53,54 to plate 6.Be crushed on which cover

plate

53,54 according to plate 6, relevant contact separation will be finished which switching function (normally opened contact or normally-closed contact).If contact separation becomes the normally opened contact form as illustrated in fig. 3, wherein fixed contact 1 is arranged on lower cover 54 belows, and then plate 6 is forced on the lower cover 54.When causing this contact separation closed in slide block 7 motions, armature contact 2 contact fixed contacts 1.Because engage contacts, plate 6 can no longer be pushed when slide block 7 continuation are mobile, but compression press spring 55.The compression of arrangement pressure by stage clip 55 that armature contact 2 is pressed on the fixed contact 1 is enhanced.

When contact separation was designed to normally-closed contact, fixed contact 1 was positioned at the top of the upper cover plate 53 of cage 50, thereby plate 6 is pressed towards upper cover plate 53 (seeing the left side the first arm 41 of Fig. 6).Stage clip 55 preferably becomes the form of helical compression spring, and its end bearing is on a cover plate 53 of cage 50, and the other end is bearing on another cover plate 54.As the replacement mode, stage clip 55 for example can become the form of leaf spring.

When stage clip 55 is designed to helical compression spring, the remote control switch preferred implementing form shown in reference to the accompanying drawings, forming section 56 is placed on one of them cover

plate

53,54 of plate 6 and cage 50, the end of laying stage clip 55 on forming section.Forming section 56 preferably becomes domed shape, but also it can be designed to the shape of cylindrical pin.

The

inner face

57,58 of

cage sidewall

51,52 is parallel to each other and extends and sharp angle of relative slide block 7 moving directions, 14 inclinations.This sharp angle is preferably 3 °-5 °.

As mentioned above, if armature contact 2 is pasting fixed contact 1 under it, the plate 6 that these armature contacts 2 then are housed is lifted away from their cage 50

cover plates

53,54 of supporting and compression press spring 55 correspondingly.

Causing armature contact 2 to be lifted away from slide block 7 moving process of fixed contact 1 under it, armature contact 2 at first is not lifted away from fixed contact, and plate 6 is pressed to fixed contact 1 together with armature contact 2 by stage clip 55, here, when slide block 7 continuation are mobile, remove the pressure of stage clip 55.Have only the

cover plate

53,54 when cage 50 to be bearing on the plate 6, they just are moved and armature contact 2 is lifted away from fixed contact 1.

The cage 50 that takes place before being lifted away from is in the process that plate 6 moves, and the

inner face

57,58 of

cage sidewall

51,52 slides along plate 6.Because

inner face

57,58 relative slide block 7 moving directions 14 tilt, so plate 6 moves perpendicular to moving direction 14 ground.So, armature contact 2 is parallel to armature contact and moves with those faces of its fixed contact that reclines.In its trend perpendicular to moving direction 14 or be lifted away from the side direction relative motion of armature contact 2 relative fixed contacts 1 of motion the seam between the

separate contacts

1,2 fast.

Causing armature contact 2 to abut under it in 7 motion processes of slide block on fixed contact 1, as mentioned above, armature contact 2 is at first pasting fixed contact 1, and continues when mobile when slide block 7, and the stage clip 55 that acts on plate 5 is compressed.In this compression process,

inner face

57,58 also slides along plate 6, and this mobile trend that causes armature contact 2 is perpendicular to moving direction 14.In addition, owing to armature contact 2 has abutted on the fixed contact 1, thus armature contact 2 friction fixed contacts 1, the result, the placement surface of two

contacts

1,2 obtains cleaning.This helps to obtain little contact resistance or keep this slight drag in the useful life of remote control switch.
