Embodiment
It should be appreciated that specific embodiment described herein is not used to limit this only to explain the utility model
Utility model.
Microswitch as shown in Figures 1 to 4, include the upper lid 3 and drain pan 5 of mutual clamping, between upper lid 3 and drain pan 5
Micromotion mechanism is provided with, the micromotion mechanism includes normally closed terminal 8, normally opened terminal 7, public terminal 6, bullet are had a sudden inspiration structure and pressing machine
Structure.
One end of wherein normally closed terminal 8, normally opened terminal 7 and public terminal 6 from right to left successively with the clamping of drain pan 5；It is normally closed
The other end of terminal 8 and normally opened terminal 7 occupy the top and middle part of the inside right-hand member of drain pan 5 respectively, and the other end of public terminal 6 is set
In the middle top of the inside left end of drain pan 5；As shown in Figure 5, Figure 6, the fixation of the first fixing end 61, second is provided with public terminal 6
End 62 and the 3rd fixing end 63, the first bayonet socket 611 is provided with the first fixing end 61, the second card is provided with the second fixing end 62
Mouth 621, the 3rd fixing end 63 is fastened on drain pan 5；Normally opened terminal 7 is upwardly extended by the one end being connected on drain pan 5 and bending
The first support base 71 is formed, normally opened terminal contact 9 is provided with the first support base 71；Normally closed terminal 8 is by being connected on drain pan 5
One end upwardly extends rear bending and forms the second support base 81, and normally closed terminal contact 10 is provided with the second support base 81.
As shown in Figure 2 and Figure 3, bullet structure of having a sudden inspiration includes shell fragment 4, tongue piece 12 and shrapnel contact 11, and shrapnel contact 11 is arranged on bullet
One end of piece 4, the first through hole 41 passed through for the fixing end 61 of public terminal 6 first, first through hole are provided with the other end of shell fragment 4
The first neck 411 for the first fixing end of clamping 61 is provided with 41；It is provided with the shell fragment 4 of the position of tongue piece 12 for public
Second through hole 42 of the fixing end 62 of terminal 6 second through fixation altogether.Tongue piece 12 is to be arranged on shell fragment 4, and protruding upward in bullet
The arcuate structure of piece 4, and one end of tongue piece 12 is fixedly connected with shell fragment 4, the other end is provided with the second neck 121., will during installation
After second fixing end 62 passes through the second through hole 42, the second neck 121 on tongue piece 12 is snapped fit onto to the in the second fixing end 62
