Specific implementation mode
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings to this
The specific implementation mode of utility model is described in detail.
As shown in attached drawing 1, Fig. 2 and Fig. 3, a kind of microswitch structure for strip resistance that the present embodiment discloses, including switch
Shell and the button 1 being arranged in switch case, switch case include switch pedestal 2 and the glue shell 3 that is fastened with switch pedestal 2,
Glue shell 3 is the hollow shell of upper and lower opening, and 1 upper end of the button extends 3 top of plastic emitting shell for pressing, switch pedestal by opening
2 form cavity when being fastened with glue shell 3, and spring 4 is provided in the cavity, and spring 4 is arranged between switch pedestal 2 and button 1,
When button 1 is pushed by external force, spring 4 deforms upon, and when the external force of button 1 disappears, spring 4 restores deformation, and button 1 is made to restore former
Shape.
It in the present embodiment, is provided in switch pedestal 2 towards the fixed column 21 being arranged in switch case, i.e., towards in cavity
Setting is equipped with two terminals 6 being connect with external circuit in the fixed column 21 and is arranged between two terminals 6 for cutting
Change the connector 5 that two terminals 6 are turned on or off, the hinge that connector 5 is electrically connected as two terminals 6, it will be understood that when
When connector 5 is connect with two terminals 6, then above-mentioned microswitch conducting, when connector and two terminals 6 are not connected to, then on
State microswitch disconnection.
In the present embodiment, connector 5 includes two flexible connection pieces 51 and the electricity being connected on two flexible connection pieces 51
Resistance 52, wherein there are two the settings of flexible connection piece 51, is just corresponded with two terminals 6, when two flexible connection pieces 51 divide
When not connect with two terminals 6, then above-mentioned microswitch conducting.Flexible connection piece 51 is U-shaped structure, which is inserted in
In fixed column 21, coordinate stud so that flexible connection piece 51 is fixed in fixed column 21.Wherein, resistance 52 is as connection two
The component of flexible connection piece 51, it is preferred that resistance 52 is Chip-R, while while being also connected as above-mentioned microswitch generates
The resistance value size of resistance conversion signal, resistance 52 can design according to actual needs, no longer discuss herein.
There are a variety of connection types, for example, having arc on flexible connection piece 51 between flexible connection piece 51 and resistance 52
Structure, 52 end of resistance squeeze and are fixed on arcuate structure so that resistance 52 is conducted with flexible connection piece 51.Further, exist
