Description
Technical field
The utility model relates to a kind of switch, particularly extension spring action sensitive switch.
Background technology
Sensitive switch is a kind of quick converting switch of exerting pressure and actuating, because the contact spacing of its switch is smaller, therefore named sensitive switch is again sensitive switch.
Sensitive switch mainly is comprised of housing, movable palping foot, leg, middle pin, button and return unit, above-mentioned return unit mostly adopts spring leaf, such as the sensitive switch of published China Patent No. 200810163021.X, resetting of its movable palping foot realizes by the reed that is connected between middle pin and the movable palping foot exactly.But because the elastic deformation of reed self is poor, so that the useful life of whole sensitive switch is short, the stability that resets simultaneously is also poor.
The utility model content
The purpose of this utility model is the extension spring action sensitive switch that a kind of long service life is provided in order to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, the extension spring action sensitive switch that the utility model is designed, comprise the housing that is formed by protecgulum and bonnet and place pin in the housing, movable palping foot, leg, fork pin and button, described housing is provided with the button groove, middle pin groove and leg groove, the button activity plug is connected in the button groove, middle pin extends housing by above-mentioned middle pin groove, leg extends outside the housing by the leg groove, movable palping foot is between middle pin and leg, and an end cooperates with leg, its other end and middle pin apical grafting, and middle pin is provided with the installation slotted hole, slotted hole is installed is arranged in the position of pin and movable palping foot phase apical grafting, fork pin apical grafting is below button, and the other end is plugged on the lower end that slotted hole is installed, and is penetrated with spring in the above-mentioned installation slotted hole, one end of described spring is connected with the fork pin, and its other end is connected with movable contact spring.
In order to promote conduction sensitivity of the present utility model, the leg abutting end riveted joint at movable palping foot in the utility model has silver contact, and same riveted joint has silver contact on the movable palping foot abutting end of leg, and above-mentioned two silver contacts are oppositely arranged.
The extension spring action sensitive switch that the utility model obtains, resetting of its movable palping foot realizes that by the spring that is connected between fork pin and the movable palping foot compare and reed of the prior art, the elastic deformation performance of above-mentioned spring is good exactly, so that long service life, Simultaneous Stabilization might as well.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment 1:
Extension spring action sensitive switch in Fig. 1, it comprises the housing that is comprised of protecgulum 1 and bonnet 2 and places pin 4 in the housing, movable palping foot 5, leg 9, fork pin 7 and button 3, described housing is provided with button groove 2-3, middle pin groove 2-1 and leg groove 2-2, button 3 motion stops are connected in the button groove 2-3, middle pin 4 extends housing by above-mentioned middle pin groove 2-1, leg 6 extends outside the housing by leg groove 2-2, movable palping foot 5 is between middle pin 4 and leg 6, and an end cooperates with leg 6, its other end and middle pin 4 apical graftings, middle pin 4 is provided with installs slotted hole 4-1, slotted hole 4-1 is installed is arranged in the position of pin 4 and movable palping foot 5 phase apical graftings, fork pin 7 apical graftings are below button 3, and the other end is plugged on the lower end that slotted hole 4-1 is installed, be penetrated with spring 8 in the above-mentioned installation slotted hole 4-1, an end of described spring 8 is connected with fork pin 7, and its other end is connected with movable palping foot 5.
In specific works, the button 3 of present embodiment contact with welding 6 thereby drive movable palping foot 5 actions by the external force action of exerting pressure, and at this moment is connected between fork pin 7 and the movable palping foot 5 spring 8 generation deformation and strains, after the external force on the button 3 disappeared, movable palping foot 5 resetted by spring 8 again.
Embodiment 2:
Such as Fig. 2, Fig. 3 and extension spring action sensitive switch shown in Figure 4, its general structure is consistent with embodiment 1, but in order to promote the conduction sensitivity of present embodiment, leg abutting end riveted joint at movable palping foot 5 in the present embodiment has silver contact 9, same riveted joint has silver contact 9 on the movable palping foot abutting end of leg 6, and above-mentioned two silver contacts 9 are oppositely arranged.
