Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
With embodiment, invention is described in detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present invention propose a kind of low pressure Magnetic Control switch, including switch upper body 1 and with switch upper body 1
Match the switch lower body 2 installed, and forms one and install chamber resettling between switch upper body 1 and switch lower body 2.
The upper inside of this switch upper body 1 is provided with the nylon sliding sleeve 3 being closely attached on switch medial wall, upper body, nylon sliding sleeve 3
Between the inner top surface of upside and switch upper body, pressurized barrier film 4 is installed, described in the open the light top of upper body there is interface section 5, connect
Oral area divides the inside of 5 to have and runs through interface section and be communicated to switch pressure medium conduction aperture 6 within upper body.
The bottom of nylon sliding sleeve 3 is provided with the magnetic core A 7 being placed in switch upper body bosom, and the set of this nylon sliding sleeve 3
Inside is provided with the magnetic core set 8 that cross section is T-shaped, and the upper part coupling of magnetic core set 8 is slidably mounted on inside the ring of nylon sliding sleeve 3, magnetic
The lower part coupling of core retainer plate is inserted into inside the ring of magnetic core A 7, and the inside of the lower part of this magnetic core set is provided with a pair phase and repels peace
The magnetic core B 9 of dress and magnetic core C 10, magnetic core C 10 are arranged on below magnetic core B and the pole orientation of magnetic core C and the magnetic pole side of magnetic core A
To identical.
The top of switch lower body 2 is provided with backstop and holds out against the nylon jacket 11 in magnetic core A, and the bottom of nylon jacket 11 is provided with coupling peace
Being contained in the nylon block 12 on switch lower body medial wall, the inside of nylon block 12 is provided with and is correspondingly arranged at touching below magnetic core set 8
Switch 13, the top of touch-switch 13 is provided with the magnetic conductor 14 facilitating magnetic core C 10 to touch touch-switch.
