Guarantee the vertical sliding in push rod slideway 21 of push rod 7, it will not be because of the drive run-off the straight of switch 6.
Preferably, as shown in fig. 7, the locating plate 72 extends in the middle part of vertical portion 75 from horizontal part 74, under locating plate 72
End setting chamfering, is packed into the locating plate slideway 22 of push rod slideway 21 convenient for it.
As shown in fig. 6, the 74 front side both ends of horizontal part are respectively provided with limited post 73, limited post 73 is arranged in push rod slideway 21
Limiting slot 23 in slide up and down, limited post 73 and the distance that is moved down in push rod slideway 21 of the cooperation limitation push rod 7 of limiting slot 23,
The case where avoiding push rod 7 from excessively moving down damage moving contact component 4 and/or push rod 7 generation.
Preferably, as shown in Figures 6 and 7, excess of stroke elastic slice 750 is arranged in 75 lower end of vertical portion, presses off under test mode
When closing 6 and/or blocking, elastic deformation can occur for excess of stroke elastic slice 750, excessively move down the dynamic touching of damage to avoid because of push rod 7
The case where arch shrapnel 63 of head assembly 4 and/or switch 6, occurs.Excess of stroke elastic slice 750 and 75 lower end side of vertical portion connect
It connects, is equipped with elastic gap with the 75 lower end other side of vertical portion.
Preferably, the push rod 7 be integral type framework, be conducive to improve push rod 7 intensity and extend push rod 7 use the longevity
Life is also beneficial to reduce number of parts, reduces the assembly difficulty of electric appliance between compact electromagnetic of the present invention, saves production cost.
7 structure of push rod of the invention is not limited in above-mentioned embodiment, can also realize by other means.Example
Such as, 7 top of push rod can be connected by coil spring with casing of relay 2 or the locating plate 72 of push rod 7 is arranged in its S-shaped bullet
On the outside of piece etc..
Such as the preferred embodiment that Fig. 9-11 is switch 6 of the invention.
As shown in figure 9, the switch 6 includes the switch main body 61 of rectangular parallelepiped structure, the lower middle side part setting of switch main body 61
Operating knob 62 is arranged in arch shrapnel 63, upper middle side part, and 61 left and right ends of switch main body are respectively provided with reseting shrapnel 64, reseting shrapnel 64
The middle part of switch main body 62 is bent towards, the free end of reseting shrapnel 64 is connected with the downside of switch slideway 20, as shown in figure 11, institute
