Drive the 2nd core body 28 of central batch (-type) spring 25;

Be covered in the cover plate made from metallic plate 29 above the shell 24.

As shown in Figure 9, the inner bottom part of above-mentioned shell 24 form outstanding circular central fixed contact 30 and around the shared contact 31 of this central authorities' fixed contact 30 and be positioned at this shared contact 31 all around 4 locational around fixed contacts 32.Central authorities' fixed contact 30 and shared contact 31 and all around fixed contact 32 these contacts lead to the outside as terminal 33 from the both sides of shell 24 respectively, each terminal 33 is welded among the figure of above-mentioned printed circuit board (PCB) 5 on the unillustrated plate face (with reference to Fig. 3).In addition, the inner bottom part at shell 24 also is provided with 4 projection 24a that center on central fixed contact 30, formation positioning element 24b and wheel hub 24c on four angles of the shell 24 relative with these 4 projection 24a.

Above-mentioned central batch (-type) spring 25 and peripheral batch (-type) spring 26 are made coated with high resilience material such as phosphor bronze, SUS on mother metal, and Ag are carried out on its surface handle.Central authorities' batch (-type) spring 25 integral body are made circular (vault), are contained in to be positioned on the central fixed contact shared contact 31 on every side, and it is by the decision position, inboard of each projection 24a.On the other hand, peripheral batch (-type) spring 26 integral body are processed into rectangle, and what the position formed two columns in the central swells position 26a.Around this periphery batch (-type) spring 26 is contained on the shared contact 31 of fixed contact 32 inboards.Determine the position of this periphery batch (-type) spring 26 by the outside of the inwall of shell 24 and each projection 24a.

Above-mentioned the 1st core body 27 has cylinder 27a and from the abducent lateral margin 27b in the oblique below of this cylinder 27a, 4 of whole formation are keeping the equally spaced projection 27c of about 90 degree below this lateral margin 27b, and these four projection 27c contact with the position 26a that swells of peripheral batch (-type) spring 26.The central authorities of above-mentioned cylinder 27a offer the guide hole 34 that an above-below direction connects.Also have, constitute one at 4 tab 27d of bottom margin formation of lateral margin 27b, these four tab 27d stretch out from the centre of adjacent two projection 27c, engage with the keeper 24b of above-mentioned shell 24.The 1st core body 27 is contained on four peripheral batch (-type) springs 26 corresponding to projection 27c, and the 1st core body just can shake on shell 24 like this.Each projection 27d of this structure is inserted into corresponding positioning element 24b, therefore, and easy aligned position and after assembling, can prevent to rotate during assembling.

There is flange 28a above-mentioned the 2nd core body 28 lower ends, and the upper end of each projection 24a of the lower end of this flange 28a and shell 24 is with the interval set in opposite directions of regulation.The 2nd core body 28 inserts from the inboard of guide hole 34 belows, and highlights from the top of the 1st core body 27.Flange 28a has the effect of anticreep, and the front end of the 2nd core body 28 embeds above-mentioned block 4 just.This block 4 exposes from 2 circular port 23 is handled knob in above-mentioned rotation, handle knob 2 taper surface 23a set in opposite directions of the cone shape taper surface 4a that forms on this block 4 and above-mentioned rotation, the interval that maintenance is therebetween stipulated.In addition, at the whole projection 28b that has formed the effect of pushing of the bottom center of the 2nd core body 28, the lower end of this push projection 28b contacts with central batch (-type) spring 25.

The middle position of above-mentioned cover plate 29 has a circular centre bore 29a, and respectively there is an installing hole 29b at four angles, have formed the taper surface of downward expansion at the periphery of centre bore 29a.This cover plate 29 runs through under the state of centre bore 29a at the lateral margin 27b that makes the 1st core body 27, is riveted on installing hole 29b with injecting the wheel hub 24c that comes, and cover plate 29 just covers the upper, open end of shell 24 like this.

For the combination operation switch of formation like this, if rotating rotation, the user handles knob 2, then rotary switch 1 action; If the user topples over block 4 or pushes it, then multi-direction switch 3 actions.For example, if in case handle knob 2 to rotating rotation clockwise or counterclockwise, then just will be with the cylinder 10 of substrate 6 as the guiding face rotation with the axis body 18 of the rotor 7 of 2 interlocks of handling knob, the fixture 19 that is one with this axis body 18 also rotates in groove 13 with same direction.Like this, be riveted on each contact 21a of two

slip forks

21,22 below the fixture 19,21b, 22a, 22b just slide on the inner bottom surface of groove 13.Because two

slip forks

21,22 one-tenth 180 degree are put in opposite directions, and therefore when the contact 21b of slip fork 21 slided on A phase current potential matrix 15, the contact 22b of slip fork 22 then slided on B phase current potential matrix 16.In contrast, when the contact 21b of slip fork 21 slided on B phase matrix 16, the contact 22b of slip fork 22 then slided on A phase matrix 15.Like this, for example, a contact 21b of slip fork 21 slides on A phase matrix 15, and another contact 21a then engages, separates, so the impulse wave that the A phase signals is used is output with common matrix 14 repeatedly.At this moment, a contact 22b of slip fork 22 slides on B phase matrix 16, and another contact 22a then engages, separates, so the impulse wave that the B phase signals is used is output with common matrix 14 repeatedly.Like this, just can detect the direction of rotation of rotor 7 by the front edge of judging A phase signals and B phase signals, by the count pulse number, but the rotation amount of detection rotor 7.

7 one rotations of aforesaid rotor, the concavo-convex body 11 that the projection 20a that is contained in the ratchet spring 20 below the fixture 19 just forms with cylinder 10 bottoms repeatedly connects, breaks away from, and at this moment produces a some sense of touch.Because the number of concavo-convex body 11 is corresponding with the number of common matrix 14, therefore whenever contact 21a, 22a engages repeatedly, separates just to produce with common matrix 14 and puts a sense of touch, and this some sense of touch handled knob by rotor 7 and rotation and 2 passed to the user.And, utilize the effect of direction protrusion 19b, can prevent that projection 20a from along the circumferential direction moving (teeter), therefore, can make this projection 20a and concavo-convex body 11 successfully connect, break away from, thereby realize that real point touches work.

If the user makes and exposes to the handle knob either direction of block 4 in 4 directions all around that dispose fixed contact 32 of 2 circular port 23 of rotation and topple over, as shown in the figure, because with block 4 interlocks, the 2nd core body 28 also will be toppled over to same direction, and the 1st core body 27 is also toppled over to same direction with the 2nd core body 28.Its result, the projection 27c that is positioned at toppling direction is by the peripheral batch (-type) spring 26 that is pressed on its below, when peripheral batch (-type) spring 26 bounce-backs produce the some contact, by this periphery batch (-type) spring 26, be positioned at the fixed contact 32 and shared contact 31 conductings all around of its below, so present the state of switch closure.The angle of at this moment toppling over is restricted because of the projection 24a that the flange 28a of the 2nd core body 28 is overlapped in shell 24, and when snapping into projection 24a below the flange 28a, the 2nd core body 28 just can not further be toppled over again.Like this, just can prevent the mistake bounce-back of central batch (-type) spring 25 and contacting of central fixed contact 30.In addition, if making 28 towards 2 adjacent centres of fixed contact 32 all around of the 2nd core body topples over, 2 projection 27c that then are positioned at toppling direction push the peripheral batch (-type) spring 26 that is positioned at its below respectively, so by these two peripheral batch (-type) springs 26, be positioned at their the below around fixed contact 32 just separately with shared contact 31 conductings, thereby present switch closed condition.On the other hand, if cancel the pressing force of the 2nd core body 28 to toppling direction, so, rely on the bounce-back restoring force of peripheral batch (-type) spring 26 self, the 1st core body 27 turns back to the origin-location.Meanwhile the 2nd core body 28 also turns back to original position, so return to switch open state as shown in Figure 7.In above-mentioned occasion, owing to form taper surface at the edge of the centre bore 29a of cover plate 29, therefore the 1st core body 27 can successfully return to the origin-location.

Also have, if the user pushes block 4 straight downwards, then as shown in figure 11, the 2nd core body 28 descends along the guide hole 34 of the 1st core body 27, so push projection 28b pushes the central batch (-type) spring 25 that is positioned at its below.And, when central batch (-type) spring 25 bounce-backs produce the some contact,, be positioned at the central fixed contact 30 and shared contact 31 conductings of its below, thereby present switch closed condition by this central authorities' batch (-type) spring 25.In this occasion, the 1st core body 27 plays the effect of the guiding part of guiding the 2nd core body 28 push action simultaneously because the support of 4 peripheral batch (-type) springs 26 forms neutral condition.If cancel to the 2nd core body 28 under pressing force, then rely on self bounce-back restoring force of central batch (-type) spring 25, the 2nd core body 28 and block 4 return original position, return to switch open state as shown in Figure 7.

As mentioned above, the combination operation switch of present embodiment, not only can from rotary switch 1, produce the consecutive pulses signal by handle knob 2 spinning movement of rotation, but also can from multi-direction switch 3, produce 4 kinds of on/off switch signals that make required 1 peripheral batch (-type) spring 26 and fixed contact 32 all around distinguish conductings by the toppling direction of selecting

block

4,4 kinds of on/off switch signals with making 2 required adjacent peripheral batch (-type) springs 26 and the 32 difference conductings of fixed contact all around amount to 8 kinds of on/off switch signals.And then 4 pressure also can produce the on/off switch signal by action from multi-direction switch 3 by blocking a shot.Therefore, the range of application of combination operation switch can be expanded widely.For example, the combination operation switch of present embodiment is applied to the occasion of audio devices, can by block a shot 4 topple over select a menu the various menus of operation on being shown in display such as LCD after, confirm selected menu by 4 the pressing operation of blocking a shot, and then by rotating rotation 2 volume and the tonequality of regulating selected menu of handling knob.

The present invention is if then can obtain following effect by above explanation:

Be equiped with order output and utilize the spinning movement of rotor and opening of producing, close the rotary switch that switches signal, output utilizes toppling over of core body to move and the multi-direction switch of the switching signal that the switching signal of generation produces with utilizing the push action of core body respectively, and an opening is set and above-mentioned multi-direction switch is disposed at middle position and be the combination operation switch of its feature in this opening at above-mentioned rotary switch, can produce pulse signal by the spinning movement of rotor, the operation generation on/off switch signal of toppling over by core body reaches the push action generation on/off switch signal that passes through core body respectively, so the scope of application of this combination operation switch is widened significantly.
