To that should have the second operating knob, and the second operating knob and the first operating knob lower inside are installed with movable levers, described movable
Lever, which is located at, is connected with the first elastic force bullet between microswitch body interior, and movable levers one end and microswitch inner body wall
Spring, one end of the action reed is in contact with movable levers, and action reed both sides are opened by the second elastic spring and fine motion
Close inner body wall to be connected, the first make contact is in contact with normally closed interlock, and second contact point is relative with normally open contact
Should.
It is preferred that, first operating knob and the second operating knob are mutually perpendicular to movable levers.
It is preferred that, the movable levers are mutually perpendicular to action reed.
It is preferred that, the first make contact and the second contact point are located at the upper and lower sides for acting reed one end, and position respectively
It is interspersed.
It is preferred that, the spacing range between second contact point and normally open contact is 2-5mm.
Compared with prior art, the beneficial effects of the utility model are：The microswitch of the service life length is provided with two
Operating knob, can not be normally carried out after work when after an operating knob long-time use, can be made by another operating knob
Microswitch body carries out normal work, so can effectively improve the new service life by two operating knobs, make
Good with effect, first make contact and the second contact point are interspersed, thus can respectively with normally closed interlock and normally open contact
It is in contact, it is rational in infrastructure.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of microswitch of service life length, including
Microswitch body 1, sealing ring 2, the first drive rod 3, the first operating knob 4, the second drive rod 5, the second operating knob 6, movable thick stick
Bar 7, the first elastic spring 8, action reed 9, the second elastic spring 10, first make contact 11, the second contact point 12, normally closed interlock
13 and normally open contact 14, the first drive rod 3, the first operating knob 4, the second drive rod 5 and second are provided with microswitch body 1
Sealing ring 2, first are installed with operating knob 6, and the first operating knob 4 and the microswitch body 1 in the outside of the second operating knob 6
The operating knob 6 of operating knob 4 and second is mutually perpendicular to movable levers 7, passes through 5 pair first of the first drive rod 3 and the second drive rod
The power that the operating knob 6 of operating knob 4 and second applies can pass to movable levers 7 with maximized, and break-make is rapid, the first drive rod 3
Lower section is to that should have the first operating knob 4, and the lower section of the second drive rod 5 is to that should have the second operating knob 6, and the second operating knob 6 and the first behaviour
Make the lower inside of button 4 and be installed with movable levers 7, movable levers 7 are mutually perpendicular to action reed 9, and movable levers 7 promote dynamic
Make reed 9 to move vertically, can so make the contact point 12 of first make contact 11 and second and normally closed interlock 13 and normally open contact 14
