In helical spring 8, as mentioned above, reach tensile force in facial 502 sides of supporting to more specifically base portion 901 of conductor plate 9() state that works. For this reason, in conductor plate 9, the power that makes base portion 901 rotate in the counterclockwise direction the 2nd rotating fulcrum B as rotating fulcrum works. Therefore, in original state, make the travelling contact 10 that arranges at base portion 901 upward the power of side shifting work, reach the state that fixed contact 403 from arranging at fixed terminal 4 has separated. For this reason, 4,5 of fixed terminals are nonconducting states, and switching device 1 reaches off-state.

The quick acting of the quick mechanism 6 that the switching device 1 that below, limit relates to the 1st embodiment with reference to Fig. 7～Figure 11 limit has describes. In the quick mechanism 6 that the switching device 1 that the 1st embodiment relates to has, be accompanied by the shake action of control member 3, at above-mentioned multiple rotating fulcrums (the 1st～3rd rotating fulcrum A～C), each structural elements limit is rotated and is carried out quick acting. Especially, an end of operating portion 301 (right-hand side end) is pushed into certain position when above operating by shake, thereby quick mechanism 6 reverses to the lower side, 4,5 of fixed terminals are switched to conducting state. On the other hand, the other end of operating portion 301 (left side end) is pushed into certain position when above operating by shake, thus quick mechanism 6 upward 4,5 of fixed terminals of side reversion be switched to nonconducting state.

Being operated an end of operating portion 301 (right-hand side end) is pushed into shell 2 when interior by shake from the original state shown in Fig. 6, in incorporating section 201, control member 3 rotates using axial region 302 as rotating fulcrum. Follow the rotation of this control member 3, the right-hand side end butt of extension 701b, the 702b of the 2nd drive division 303b and driving body 7, presses driving to left side to extension 701b, 702b. In the time being subject to pressing of the 2nd drive division 303b and driving, driving body 7 rotates using the 1st rotating fulcrum A as rotating fulcrum to counterclockwise (direction).

On the other hand, conductor plate 9 is accompanied by the rotation of control member 3 and is subject to pressing of pressing tablet 304a, 304b. In the time being subject to the pressing of pressing tablet 304a, 304b, using the 2nd rotating fulcrum B as rotating fulcrum, (other direction) is upper in the clockwise direction rotates for conductor plate 9. Be accompanied by the rotation of this driving body 7 and conductor plate 9, protrusion tab 705 side shifting upward, on the other hand, the base portion 901 of conductor plate 9 moves to the lower side. Consequently, the 2nd rotating fulcrum B side shifting upward, on the other hand, the 3rd rotating fulcrum C moves to the lower side and reaches the state shown in Fig. 7. In Fig. 7, show quick mechanism 6 in the switching device 1 that the 1st embodiment relates to, that be about to the state before reversion.

, at protrusion tab 705 from the state shown in Fig. 7, upward when side shifting, the 2nd rotating fulcrum B reaches the state of the upper side that is disposed at the straight line that the 1st rotating fulcrum A is connected with the 3rd rotating fulcrum C. On helical spring 8, reach tensile force in facial 502 sides of supporting to more specifically base portion 901 of conductor plate 9() state that works. For this reason, on conductor plate 9, the power that makes base portion 901 rotate in the clockwise direction the 2nd rotating fulcrum B as rotating fulcrum works. Therefore, in the state shown in Fig. 8, the power that the travelling contact 10 arranging at base portion 901 is moved to the lower side works, thereby arrives and the state of set fixed contact 403 butts on fixed terminal 4. Thus, 4,5 of fixed terminals are set as conducting state via driving body 7 and the conductor plate 9 etc. with electric conductivity, and switching device 1 is switched to on-state.

In the switching device 1 relating at the 1st embodiment, reverse travelling contact 10 and fixed contact 403 just under the state (state shown in Fig. 8) after butt thereby adopt at quick mechanism 6, the remaining structure of tensile force of helical spring 8.

Like this, because travelling contact 10 slides on fixed contact 403, so can follow quick mechanism 6 travelling contact 10 slip and remove dust being attached on fixed contact 403 surfaces etc., so can guarantee the contact stabilization between travelling contact 10 and fixed contact 403.

On the other hand, from the state shown in Fig. 9, the other end of operating portion 301 (left side end), because shake operation is pushed into shell 2 when interior, in incorporating section 201, control member 3 rotates axial region 302 in the counterclockwise direction as rotating fulcrum. Follow the rotation of this control member 3, the left side end butt of extension 701b, the 702b of the 1st drive division 303a and driving body 7, presses driving to right-hand side to extension 701b, 702b. In the time being subject to pressing of the 1st drive division 303a and driving, using the 1st rotating fulcrum A as rotating fulcrum, (other direction) is upper in the clockwise direction rotates for driving body 7. Be accompanied by the rotation of this driving body 7, protrusion tab 705 moves to the lower side. Consequently, thus the 2nd rotating fulcrum B moves the state shown in Figure 10 that reaches to the lower side. In Figure 10, show in the switching device 1 relating at the 1st embodiment the quick mechanism 6 that is about to the state before reversion in the time restoring to original state.

In Figure 14, show relate at the 2nd embodiment in switching device 11, be about to the quick mechanism 13 of state before reversion.

As described in Figure 14 like that, when transferring to quick mechanism 13 and being about to the state before reversion, the 2nd rotating fulcrum B is configured on the straight line that the 1st rotating fulcrum A is connected with the 3rd rotating fulcrum C. In the case, the tensile force of helical spring 8 is as by more specifically base portion 151 of conductor plate 15() work to the power of the 1st rotating fulcrum A side shifting. For this reason, conductor plate 15 reaches neutral condition, and the power of rotating in the either direction in side and lower side up can not work. Therefore,, under the state shown in Figure 14, maintain the state that travelling contact 10 has separated from the fixed contact 403 that arranges at fixed terminal 4.

Further be pressed into shell 2 in an end of operating portion 121 from the state shown in Figure 14 (right-hand side end) when interior, in incorporating section 201, interior control member 12 further rotates in the clockwise direction. Be accompanied by the rotation of this control member 12, the 2nd drive division 124b further presses driving to left side to extension 141b, the 142b of driving body 14. In addition, jut 123 is pressed driving to the base portion 151 of conductor plate 15 to the lower side. Press driving according to these, driving body 14 using the 1st rotating fulcrum A as rotating fulcrum in the counterclockwise direction (direction) upper rotate and conductor plate 15 using the 2nd rotating fulcrum B as rotating fulcrum, (other direction) is upper in the clockwise direction while rotating, be accompanied by the rotation of this driving body 14 and conductor plate 15, thus recess 145 upward side shifting reach the state shown in Figure 15. In Figure 15, show that the 2nd embodiment relates in switching device 11, the quick mechanism 13 of the state after reversing just.

, at recess 145 from the state shown in Figure 14 upward when side shifting, reach the 2nd rotating fulcrum B and be disposed at the state of the upper side of the straight line that the 1st rotating fulcrum A is connected with the 3rd rotating fulcrum C. On helical spring 8, reach tensile force in facial 502 sides of supporting to more specifically base portion 151 of conductor plate 15() state that works. For this reason, in conductor plate 15, the power that makes base portion 151 rotate in the clockwise direction the 2nd rotating fulcrum B as rotating fulcrum works. And in conductor plate 15, the jut 123 of control member 12 is pressed the base portion 151 of conductor plate 15 to the lower side, the power that using the 2nd rotating fulcrum B as rotating fulcrum, base portion 151 is rotated in the clockwise direction thus works. Therefore, in the state shown in Figure 15, the power that the travelling contact 10 arranging at contact installation portion 152 is moved to the lower side works, and reaches the state contacting with the fixed contact 403 arranging on fixed terminal 4. Thus, 4,5 of fixed terminals are set as conducting state by driving body 14 and the conductor plate 15 with electric conductivity, and switching device 11 is switched to on-state. Like this, switching device 11 is the spring tension working in helical spring 8, the power that control member 12 pushes conductor plate 15 also works, thereby the structure that travelling contact 10 is contacted with fixed contact 403, the contact that therefore can increase contact is pressed, and can guarantee the contact stabilization between travelling contact 10 and fixed contact 403.

On the other hand, in the other end of operating portion 121 from the state shown in Figure 15 (left side end), because shake operation is pushed into shell 2 when interior, in incorporating section 201, control member 12 rotates axial region 122 widdershins as rotating fulcrum. Be accompanied by the rotation of this control member 12, the left side end butt of extension 141b, the 142b of the 1st drive division 124a and driving body 14, presses driving to right to extension 141b, 142b. In addition, be accompanied by the rotation of control member 12, jut 123 separates from the base portion 151 of conductor plate 15. In the time being subject to pressing of the 1st drive division 124a and driving, using the 1st rotating fulcrum A as rotating fulcrum, (other direction) is upper in the clockwise direction rotates for driving body 14. Be accompanied by the rotation of this driving body 14, recess 145 moves to the lower side. Consequently, thus the 2nd rotating fulcrum B moves the state shown in Figure 16 that reaches to the lower side. In Figure 16, what show that the 2nd embodiment relates to is about to the quick mechanism 13 before reversion in switching device 11 in the time restoring to original state.

As described in Figure 16 like that, the state of quick mechanism 13 before transferring to and being about to reverse in the time restoring to original state, the 2nd rotating fulcrum B is disposed on the straight line that the 1st rotating fulcrum A is connected with the 3rd rotating fulcrum C. In the case, the tensile force of helical spring 8 is as by more specifically base portion 151 of conductor plate 15() work to the power of the 1st rotating fulcrum A side shifting. For this reason, conductor plate 15 reaches neutral condition, and the power of rotating in the either direction in side and lower side up can not work. Therefore,, under the state shown in Figure 16, maintain the state that travelling contact 10 contacts with fixed contact 403 set on fixed terminal 4.

Further be pressed into shell 2 in the other end of operating portion 121 from the state shown in Figure 16 (left side end) when interior, in incorporating section 201, interior control member 12 further rotates in the counterclockwise direction. Be accompanied by the rotation of this control member 12, the 1st drive division 124a further presses driving to right to extension 141b, the 142b of driving body 14. Driving body 14 according to this press drive and using the 1st rotating fulcrum A when rotating fulcrum rotates in the clockwise direction, be accompanied by the rotation of this driving body 14, recess 145 moves to the lower side.

,, in the time that recess 145 moves to the lower side from the state shown in Figure 16, reach the 2nd rotating fulcrum B and be configured in the state of the lower side of the straight line that the 1st rotating fulcrum A is connected with the 3rd rotating fulcrum C. On helical spring 8, reach tensile force in facial 502 sides of supporting to more specifically base portion 151 of conductor plate 15() state that works. For this reason, on conductor plate 15, the power that makes base portion 151 rotate in the counterclockwise direction the 2nd rotating fulcrum B as rotating fulcrum works. Therefore, the travelling contact 10 that makes the to be installed on contact installation portion 152 upward power of side shifting works, and travelling contact 10 separates from the fixed contact 403 arranging at fixed terminal 4. Thus, 4,5 of fixed terminals are set as nonconducting state, and switching device 11 is switched to off-state. In addition, the jut arranging by the lower surface at control member 12 to anticlockwise rotation 123 of conductor plate 15 is restricted with the butt of base portion 151.

Like this, in the switching device 11 relating at the 2nd embodiment, be accompanied by the shake operation to control member 12, when the 2nd rotating fulcrum B moves to the upper side of the straight line that the 1st rotating fulcrum A is connected with the 3rd rotating fulcrum C, under the effect of the tensile force of helical spring 8, quick mechanism 13 to the lower side conductor plate 15 is reversed (what is called, quick acting). Consequently, 4,5 of fixed terminals are switched to conducting state, and switching device 11 reaches on-state. On the other hand, in the time that the 2nd rotating fulcrum B moves to the lower side of the straight line that the 1st rotating fulcrum A is connected with the 3rd rotating fulcrum C, under the effect of the tensile force of helical spring 8, quick mechanism 13 upward side reverses conductor plate 15. Consequently, 4,5 of fixed terminals are switched to nonconducting state, and switching device 11 reaches off-state.

In the switching device 11 relating at the 2nd embodiment, at the lower surface of control member 12, be provided with the operation of the shake to side's side that is accompanied by control member 12 and the jut 123 of pressing conductor plate 15. Thus, be accompanied by the shake operation of control member 12, press conductor plate 15 with jut 123, thus also can directly not rotate conductor plate 15 across driving body 14, so can make reliably conductor plate 15 quick actings. In addition, in switching device 11, under on-state, except the spring tension working in helical spring 8, the power that control member 12 pushes conductor plate 15 also works, the structure that travelling contact 10 is contacted with fixed contact 403, the contact that therefore can increase contact is pressed, and can guarantee the contact stabilization between travelling contact 10 and fixed contact 403.
