Abstract
A micro pressure key switch used for the electric running machine is provided. The utility model comprises an upper and lower printed circuit boards with a small clearance between each other; wherein the bottom face of the upper printed circuit board is provided with a copper foil polar plane, while the upper face of the lower printed circuit board is provided with two mutually separated copper foil polar planes, wherein the copper foil polar plane is arranged at the upper top face of the two copper foil polar planes; the upper face of the upper printed circuit board is adhered with an electronic surface film, while the upper face of the electronic surface film corresponding to the polar plane is printed with a key character; the insulating basal body of the printed circuit board is a polyester film or a polyester thin board. The utility model is good in touch and can be conducted only by the gram polar contact pressure, namely, the switch can be conducted almost free of the touch feeling. And the price is quite low, thus particularly meeting all requirements of the electric running machine.
Description
Technical field
The utility model belongs to the treadmill technical field, more particularly relates to the design of the minute-pressure power key switch that can be used for treadmill.
Background technology
Traditional sensitive switch has resistance formula soft-touch control, mechanical type sensitive switch, film key or the like.Resistance formula soft-touch control costs an arm and a leg, and is difficult to adapt to the cheap requirement of electric household treadmill.The feel of mechanical type sensitive switch and film key is relatively poor, needs big pressure just can press the sensation that does not have minute-pressure power to touch.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of minute-pressure power key switch that can be used for treadmill is provided.Its good hand touch, the touch pressure that only need restrain the utmost point gets final product conducting.Therefore, the operator very easily forms illusion: also do not contact button just conducting, the seemingly result of human body sensing.That is to say that nerve endings does not almost touch sense, just conducting of switch.It is cheap, especially adapts to the requirement of treadmill.
In order to achieve the above object, the utility model comprises having closely spaced two printed circuit board (PCB)s up and down to each other.The bottom surface of last printed circuit board (PCB) has covers the Copper Foil pole-face, has separate two above the following printed circuit board (PCB) and covers the copper foil electrode bar, cover the Copper Foil pole-face be positioned at two cover copper foil electrode bar end above.Be pasted with the electronic watch facial mask above the last printed circuit board (PCB), be printed with button character above corresponding with pole-face on the electronic watch facial mask.
After the utility model was installed, two printed circuit board (PCB)s had little gap to each other up and down.In view of two printed circuit board (PCB)s up and down respectively have certain elasticity, when pointing the corresponding position of slightly pressing the electronic watch facial mask that is printed with button character on the printed circuit board (PCB), last printed circuit board (PCB) should be located recessed downwards, it has covers that the Copper Foil pole-face moves down and separate two covers the copper foil electrode bar and contact above the printed circuit board (PCB) with following, make two to cover the conducting each other of copper foil electrode bar, minute-pressure power key switch is " opening ", just can produce an electric pulse thus.During openhanded opening, last printed circuit board (PCB) pops up and resets, and covers that the Copper Foil pole-face up moves and separate two covers the copper foil electrode bar and throw off above the printed circuit board (PCB) with following, and the disconnection of minute-pressure power key switch reverts to " pass ".
The insulating body of printed circuit board (PCB) is polyester film or polyester thin plate.Polyester film matrix good springiness is convenient to press minute-pressure power key switch and it is in time resetted.
The utility model good hand touch, the touch pressure that only need restrain the utmost point gets final product conducting.Therefore, the operator very easily forms illusion: also do not contact button just conducting, the seemingly result of human body sensing.That is to say that nerve endings does not almost touch sense, just conducting of switch.It is cheap, especially adapts to the requirement of treadmill.
Description of drawings
Fig. 1 is a structural representation cutaway view of the present utility model.
Fig. 2 is applied to schematic diagram on the treadmill for it.
Embodiment
Embodiment 1.A kind of minute-pressure power key switch that can be used for treadmill is as Fig. 1～shown in Figure 2.It comprises two printed circuit board (PCB)s 7 up and down and 8 that have little gap delta to each other.The bottom surface of last printed circuit board (PCB) 7 has covers Copper Foil pole-face 5, has separate two above the following printed circuit board (PCB) 8 and covers copper foil electrode bar 6, cover Copper Foil pole-face 5 be positioned at two cover copper foil electrode bar 6 ends above.Be pasted with electronic watch facial mask 3 above the last printed circuit board (PCB) 7, be printed with button character 4 above corresponding with pole-face 5 on the electronic watch facial mask 3.
Two printed circuit board (PCB)s 7 and 8 insulating body 1 and 2 are polyester film up and down.Polyester film matrix 1 and 2 good springiness are convenient to operate minute-pressure power key switch and it are in time resetted.
Shown in Figure 2, be pasted with electronic watch facial mask 3 above the electronic watch 10 of treadmill 9, be printed with a plurality of button character 4 on the electronic watch facial mask 3, be convenient to the body builder and control treadmill 9 as required.
When pointing the corresponding position of slightly pressing the electronic watch facial mask 3 that is printed with button character 4 on the printed circuit board (PCB) 7, this place of resilient upward printed circuit board (PCB) 7 is recessed downwards, it has cover that Copper Foil pole-face 5 moves down and with separate two cover copper foil electrode bar 6 and contact above the following printed circuit board (PCB) 8, make two to cover copper foil electrode bar 6 conducting each other, minute-pressure power key switch is " opening ".During openhanded opening, last printed circuit board (PCB) 7 pops up and resets, cover that Copper Foil pole-face 5 up moves and with separate two cover 6 disengagements of copper foil electrode bar above the following printed circuit board (PCB) 8, two to cover copper foil electrode bar 6 separated from one another, minute-pressure power key switch disconnects, and reverts to " pass ".
Embodiment 1 good hand touch, the touch pressure that only need restrain the utmost point gets final product conducting.Therefore, the operator very easily forms illusion: also do not contact button just conducting, the seemingly result of human body sensing.That is to say that nerve endings does not almost touch sense, just conducting of switch.It is cheap, especially is adapted to various treadmills, also can be used in other automatically controlled body-building apparatus or the equipment.
Claims (2)
