The reed that contact bottom face is abutted, the reed first side is abutted with the piston rod end, the reed second side and the activity
Contact bottom face is abutted, and the piston rod is arranged in a mutually vertical manner with the armature contact；
The piston rod pushes the reed and armature contact to the Switch main body when being moved to the direction close to the microswitch
Contract, now microswitch control the booster pump close；
When the direction of the piston rod to the remote microswitch is moved out the reed and armature contact, the armature contact
Overhang to the Switch main body, now microswitch control booster pump is opened.
It is provided with and is supported to outside the Switch main body in microswitch controlling device described in the utility model, in the Switch main body
Push away the spring of the armature contact.
In microswitch controlling device described in the utility model, the microswitch also includes being arranged at the Switch main body
Interior the first conductive contact for being electrically connected with the pole of booster pump first and second leading of being electrically connected with the pole of booster pump second
Electric contact.
In microswitch controlling device described in the utility model, the piston rod first end is located at the valve element and the work
Stopper rod first end end is installed with the sealing piston that can be moved in the valve element, the second end of piston rod end be pyramidal structure,
And abutted with the reed first side.
Implement microswitch controlling device of the present utility model, have the advantages that：Using of the present utility model micro-
During dynamic switch controlling device, when being that the giant of booster pump connection is closed, the hydraulic pressure rise in booster pump is caused and is pressurized
Hydraulic pressure is raised and outwards pushes piston rod in the valve element of pump connection, and piston rod is moved in the presence of hydraulic pressure to Switch main body direction
Dynamic, until piston rod pushes reed and armature contact to the Switch main body contract, now microswitch controls the booster pump to close
Close.When user opens giant, the hydraulic pressure in booster pump declines, and reed is in the presence of natural resiliency restoring force to valve element
Direction pushes piston rod, and the armature contact is overhang to the Switch main body, and now microswitch control booster pump is opened.In piston
During bar stretches out, because piston rod and armature contact are to be arranged in a mutually vertical manner, when there is slight variation in hydraulic pressure in booster pump,
Even if somewhat moving back occurs in piston rod, armature contact will not be caused to extend downwardly from once and cause booster pump accidental activation, strengthened
The stability of microswitch.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is the first state structural representation of the utility model microswitch controlling device；
Fig. 2 is the second status architecture schematic diagram of the utility model microswitch controlling device.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type embodiment is described in further detail.
As shown in Figure 1, 2, in microswitch controlling device first embodiment of the present utility model, the microswitch 4 is controlled
Device 1 processed is arranged in booster pump and controls the booster pump shutdown or startup, the control according to hydraulic pressure in the booster pump is high or low
Valve element 2 that device 1 includes connect with the booster pump, movable it is arranged at that the valve element 2 is interior and the extended piston to outside the valve element 2
Bar 3, match somebody with somebody with the piston rod 3 and merges for controlling the microswitch 4 of the booster pump shutdown or startup, the microswitch 4 is including opening
Body 5 is closed, movable be arranged in the Switch main body 5 and extended armature contact 6 to outside the Switch main body 5, be arranged at this
The reed 7 that the bottom of Switch main body 5 is abutted with the bottom face of armature contact 6, the first side of reed 7 is supported with the end of piston rod 3
Connect, the second side of reed 7 is abutted with the bottom face of armature contact 6, the piston rod 3 is arranged in a mutually vertical manner with the armature contact 6；
