As shown in Figure 2,3, the acting arm component includes acting arm 6, and one end of the acting arm 6 is arranged in the button
3 lower sections, the other end are arranged between normally opened terminal 51 and normally closed terminal 52, are arranged in the acting arm 6 in the normally opened terminal
The bottom of one end between 51 and normally closed terminal 52 is provided with dynamic silver contact 61；
The lower section of the acting arm 6 is provided with acting arm bracket 7, one end of the acting arm bracket 7 and the base body 1
Clamping, the other end are connect with the mounting terminal 53；The lower section of the acting arm bracket 7 is provided with connection sheet 8, the acting arm
Elastic slice 9 is provided between 6 and acting arm bracket 7.
One end of the acting arm 6 is provided with the first clamping block 62, and the first clamping groove 81 is provided in the connection sheet 8,
The first clamping block 62 in the acting arm 6 is connected in the first clamping groove 81 of the connection sheet 8, and the one of the acting arm 6
There are two wedge shaped projections 64 for end setting, and there are two be clamped boss 71 for one end setting of the acting arm bracket 7；
One end of the connection sheet 8 is provided with the second clamping block 82, and the other end of the connection sheet 8 is provided with third clamping
Block 83 is provided with the second clamping groove 72 on the acting arm bracket 7, cavity 62, the connection sheet is provided in the acting arm 6
Third clamping block 83 on 8 extends the cavity 62 in the acting arm 6, the second clamping block 82 clamping in the connection sheet 8
In the second clamping groove 72 on the acting arm bracket 7；
One end of the elastic slice 9 is provided with the 4th clamping block 91, and the other end of the elastic slice 9 is provided with third clamping groove
92, the 4th clamping groove 73 is provided on the acting arm bracket 7, the 4th clamping block 91 on the elastic slice 9 is connected to described dynamic
In the 4th clamping groove 73 on contact arm bracket 7, the 5th clamping block 63, the 5th clamping block 63 are provided in the acting arm 6

When push button 3, button 3 drives connection sheet 8 downward for fulcrum with the second clamping groove 72 on acting arm bracket 7
Rotation, so that acting arm 6 be driven to rotate down, when the angle of acting arm 6 and connection sheet 8 is less than zero degree, acting arm 6 can be in bullet
It beats downwards under the action of piece 9, then the normally opened silver contact 511 on the dynamic silver contact 61 and normally opened terminal 51 in acting arm 6 connects
Touching, realizes the turn-on power loss of switch, while elastic slice 9 is compressed.Its principle is: when acting arm 6 is beated downwards, due to dynamic touching
There are two wedge shaped projections 64 for the setting of 6 left end of arm, and setting is moved down there are two boss 71 is clamped in acting arm 6 on acting arm bracket 7
In the process, the wedge shaped projection 64 of 6 left end of acting arm can be stuck on the clamping boss 71 of contact arm bracket 7, so that 6 left end of acting arm
The distance that moves down be restricted, and the right end of acting arm 6 can move freely, so that 6 right side of acting arm moves down distance
Distance is moved down greater than 6 left side of acting arm, therefore, the normally opened silver touching on the dynamic silver contact 61 and normally opened terminal 51 in acting arm 6
511 contact of point, realizes the turn-on power loss of switch, while elastic slice 9 is compressed.
When decontroling button 3, elastic slice 9 resets, and acting arm 6 can beat upwards under the action of elastic slice 9, then acting arm 6
On dynamic silver contact 61 and normally opened terminal 51 on normally opened silver contact 511 contact, realize the normally closed brake function of switch.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
