Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Shown in Fig. 2～6, hilted broadsword mains switch described in the utility model, comprise the pedestal 1 and the iron-clad 6 that fasten up and down, the push rod 2 of convex shape is located in the pedestal 1 and handle end exposes

pedestal

1,1 of the handle end of push rod 2 and pedestal are provided with bearded needle 9 that plays the role of positioning and the spring 10 that plays reset response, the right side, middle part of pedestal 1 is provided with Chang Kaiduan 3, the left side, middle part is provided with public terminal 4, the end that Chang Kaiduan 3 is positioned at pedestal 1 is provided with fixed contact 31, it is characterized in that: the end that public terminal 4 is positioned at pedestal 1 is branched into button bit A41, button bit B43, the top of button bit A41 is provided with detent 42, shell fragment 7 is located in the pedestal 1, its central authorities are provided with an elasticity arm of force 72, front end is provided with the moving contact 5 adaptive with fixed contact 31, the cambered surface 61 of the male and fomale(M﹠F) 62 of both sides and push rod 2 lower surfaces is adaptive, the rear and front end of the elasticity arm of force 72 is respectively equipped with draw-in groove A71, draw-in groove B73, draw-in groove A71, draw-in groove B73 respectively with button bit A41, button bit B43 engaging, the head of the elasticity arm of force 72 is pressed in the detent 42

On the basis of technique scheme, be respectively equipped with the some grooves that hold bearded needle 9 and spring 10 on the push rod 2, bearded needle 9 is positioned in the corresponding recesses on the push rod 2 by stage clip 8.Being provided with of bearded needle 9, spring 10 and groove can be adopted existing techniques in realizing.

The utility model in use, pressing handle end makes push rod 2 travel forward, because the male and fomale(M﹠F) 62 of the elasticity arm of force 72 both sides and the cambered surface 61 of push rod 2 are adaptive, the displacement of push rod 2 has just promoted shell fragment 7, applied active force for by this elasticity arm of force 72, shell fragment 7 is by the effect of the elasticity arm of force 72, and the moving contact 5 on the shell fragment 7 is contacted with fixed contact 31 on Chang Kaiduan 3, forms electric pathway.Because of the elasticity arm of force in the middle of the shell fragment and public terminal pressuring action, with pushrod movement to bearded needle locking-in state the contact of Chang Kaiduan is applied contact pressure, and shell fragment remains stable contact condition and mistake electric energy power with public terminal in motion process.

Good effect of the present utility model is as follows: the utility model is in the motion process of push rod, and shell fragment 7 can keep the state that presses with public terminal 4, and electric conductivity is stable; Because single shell fragment 7 directly is stuck on the public terminal 4, so reduced amount of parts and assembly process, greatly provide cost savings, improved production efficiency.
