When the bulldozing operation removed under this state functional unit 11, by the application of force that resets of reset components 19, travelling contact 17 is crushed on the top, thereby makes the off position of functional unit 11 before travelling contact 17 resets to the operation that is pressed.At this moment, along with travelling contact 17 resets, the 57k of contact section of travelling contact 17 and switching fixed contact 15k and insulation division 18 are separated from each other, and switching device 101 makes switch be in the OFF state.
As mentioned above, such as Fig. 3, Fig. 5 and shown in Figure 8, switching device 101 of the present utility model, the 57k of contact section of travelling contact 17 with switch before fixed contact 15k contacts, become conplane insulation division 18 via the sliding contact surface 15p that is set as the switching fixed contact 15k that slides with the 57k of contact section and arrive at switching fixed contact 15k, so initial clamping the 57k of contact section of insulation division 18, thereby can slide sleekly and switch fixed contact 15k and be connected at insulation division 18.By the way, even the direction (the roughly direction of quadrature) (left and right directions among Fig. 8) that the position of switching fixed contact 15k and the 57k of contact section intersects at the moving direction with the 57k of contact section (travelling contact 17) is upper variant, also can proofread and correct its difference by the initial clamping insulation division 18 of the 57k of contact section, thereby can make the 57k of contact section that switches fixed contact 15k and travelling contact 17 almost at the same position butt.Therefore, the impacts such as alignment error when being subject to the uneven and assembling of the CHI-pulse and CUN-pulse being irregular of parts, even the direction (the roughly direction of quadrature) i.e. that the position of the 57k of contact section of travelling contact 17 and the position of switching fixed contact 15k intersect at the moving direction of the travelling contact 17 (57k of contact section) that brings with the push operation of the functional unit 11 opposed direction of a 57k of docking point section misplaces, also can improve the caused switching time precision from OFF to ON of push operation of functional unit 11.
Such as Fig. 9 and shown in Figure 10, this insulation division 18 is set as and with setting the 13s of section is set and becomes one and from setting the 13s of section is set and extends, so can switch the top configuration insulation division 18 of fixed contact 15k reliably.And, compare the dislocation of the insulation division 18 that the 57k of contact section that can prevent travelling contact 17 brings when butt or when sliding etc. or come off etc. with the situation that is provided with insulation division 18 as single component.By the way, can and switch on the fixed contact 15k the reliably 57k of contact section of sliding contact travelling contact 17 at insulation division 18, thereby more can improve the switching time precision from OFF to ON.
And such as Fig. 9 and shown in Figure 10, the mid portion that be embedded in part on the base portion 13k of insulating body 13, namely switches fixed contact 15k and splicing ear 55k has the bend 55s of S word shape.Therefore, the heat from splicing ear 55k that produces when mounting switching device 101 by welding can reduce its heat conduction.
And, such as Fig. 3, Fig. 5, Fig. 9 and shown in Figure 10, to arrange under the state that the 13s of section has been close to erectting in length range in the part of the metallic plate plate face that consist of to switch fixed contact 15k, switch fixed contact 15k and be insulated matrix 13 maintenances, switch fixed contact 15k and 18 one-tenth same plane states of the insulation division that is arranged on its top so can make accurately.By the way, can make the 57k of contact section from sleekly sliding contact of insulation division 18 to switching fixed contact 15k, can prevent from when two-way contact, occurring the phenomenons such as vibration.Thereby, can more improve the switching time precision from OFF to ON.
And as shown in Figure 3, reset components 19 is made of disc spring 19C.And disc spring 19C is configured in public fixed contact 15C and switches between the fixed contact 15k.And, because the upper end and the back side 17b butt that is connected base portion 17j (with reference to Fig. 7) of disc spring 19C, in the middle of disc spring 19C is in compressive state, so travelling contact 17 is subject to towards the top elastic force-applying of (functional unit 11 sides) by disc spring 19C.
By the way, because configuration is as the disc spring 19C of reset components 19 between public fixed contact 15C and switching fixed contact 15k, disc spring 19C is to travelling contact 17 application of forces, so can balance keep well travelling contact 17, can configure accurately and switch fixed contact 15k and travelling contact 17.By the way, the 57k of contact section of travelling contact 17 stably is connected on the switching fixed contact 15k, thereby more can improves the switching time precision from OFF to ON.
Such as Fig. 9 and shown in Figure 10, in the boundary face of switching between fixed contact 15k and the insulation division 18, be provided with to the side-prominent convex shaped part 56 of insulation division 18 switching fixed contact 15k, and form the chimeric concavity section 16 of convex shaped part 56 in insulation division 18 sides.And, as shown in Figure 9, the long side direction of the convex form of convex shaped part 56 form along with the direction of the sliding contact surface 15p same level direction of switching fixed contact 15k.In addition, different from the 1st execution mode, fixed contact 15k arranges concavity section 16, at insulation division 18 convex shaped part 56 to be set also passable switching.
By the way, any sides in the middle of switching fixed contact 15k and insulation division 18 are provided with convex shaped part 56, and be provided with the concavity section 16 chimeric with convex shaped part 56 at opposite side, thereby can switch more reliably the location of fixed contact 15k and insulation division 18, can make more accurately the insulation division 18 that switches fixed contact 15k and arrange on its top maintain the same plane state.Therefore, can make the switching time from OFF to ON keep for a long time the high accuracy state.
And, such as Fig. 3 and shown in Figure 6, at the lateral wall of the pedestal 13d of insulating body 13, when overlooking pedestal 13d with form and lock flank 13r across switching the opposed position of fixed contact 15k and the 57k of contact section.As shown in Figure 3, this locking flank 13r forms respectively to the bearing of trend of 2 fixed contacts 15 (switching fixed contact 15k, public fixed contact 15C) and extends.
And, as shown in Figure 1, although being integral, insulating body 13 and shell 14 consisted of cover 12, but such as Fig. 1 and shown in Figure 3, determine to lock in advance the position dimension of flank 13r and shell 14 inwall 14w, thereby when in the storage part 12s of shell 14, inserting pedestal 13d, locking flank 13r is out of shape according to the inwall 14w (with reference to Fig. 4) of shell 14.
By the way, owing to being provided for locking the shell 14 that formed functional unit 11 guide part 14g and the locking flank 13r of insulating body 13 at the outer wall of being located at the pedestal 13d on the insulating body 13, and should lock flank 13r respectively when overlooking pedestal 13d with configure across switching fixed contact 15k and the contact section opposed position of 57k, so exactly mounting casing 14 and insulating body 13 and do not become flexible, and can improve the positional precision of switching fixed contact 15k and travelling contact 17.By the way, can more improve the switching time precision from OFF to ON that the push operation of functional unit 11 is brought.
And, such as Fig. 3 and shown in Figure 8, being at functional unit 11 under the state of off position, the 57k of contact section separates with insulation division 18.By the way, even because of the repeatable operation switch, the contact strip and the switching fixed contact 15k that are for example formed by silver that consist of the 57k of contact section of travelling contact 17 and travelling contact 17 are worn, make its wearing and tearing pruinescence travelling contact 17 (57k of contact section) bring into and be attached on the insulation division 18, also can guarantee to switch the insulating properties of fixed contact 15k and travelling contact 17.By the way, can improve the reliability of switching device 101, and can increase the service life.
And such as Fig. 7 and shown in Figure 8, a pair of elastic arm 17w of travelling contact 17 forms horse-hof shape, does not extend with the projected direction of the free end side that is connected base portion 17j link to operating portion 11t.For this reason, can make insulation division 18 be not from the free end side of a pair of elastic arm 17w but from be connected the side that base portion 17j connects and enter between the 57A of docking point section.Thus, the impacts such as alignment error in the time of can preventing and assembling uneven because of the CHI-pulse and CUN-pulse being irregular of parts, a pair of elastic arm 17w and insulation division 18 butts make a pair of elastic arm 17w distortion.
And, as shown in Figure 8, being provided with the spigot surface 18g of the 57k of contact section sliding contact on the top of insulation division 18, the width of this spigot surface 18g narrows down gradually along with leaving switching fixed contact 15k.For this reason, when the 57A of a docking point section clamping insulation division 18, can make insulation division 18 round and smooth and arrive at reliably between the 57A of docking point section.Thus, can prevent more reliably that a 57A of docking point section and insulation division 18 butts from making a 57A of docking point section distortion, and can more suppress the wearing and tearing of a 57A of docking point section and insulation division 18.
