Embodiment
At first, see also Fig. 1 to Fig. 3, had structurally improved key switch by the utility model provides, it mainly is made up of a pedestal 1, one first electric-conductor 21, one second electric-conductor 22, an electroconductive elastic sheet 3 and a button 4.
This pedestal 1 is a ware shape container, and it has a bottom 11 and and is located on this bottom 11 peripheries and upwardly extending sidewall 12, and the inner ring of this sidewall 12 is provided with a groove 121.This first electric-conductor 21 and this second electric-conductor 22 are embedded in this bottom 11, and this first electric-conductor 21 is not in contact with one another each other with this second electric-conductor 22.
This electroconductive elastic sheet 3 is arciform and tool elasticity, strides with its periphery and is located on this first electric-conductor 21.This button 4 places this electroconductive elastic sheet 3 tops, and when the application of force was pushed this button 4, this electroconductive elastic sheet 3 was that stress deformation is recessed and contact with this second electric-conductor 22, and causes current path by this; And when stopping to force in this button 4, this electroconductive elastic sheet 3 is that elastic recovery breaks away from this second electric-conductor 22 to original state, causes current interruption by this, and with these button 4 top repositions.In addition on this pedestal 1, also be provided with a lid 5, against this button 4, by this, these lid 5 application of forces pressed down or when stopping the application of force with this lid 5, but the switching of these button 4 control circuits of interlock.
This button 4 is made with the flexual flexible material of tool, for example silica gel, rubber etc.Lateral margin around this button 4 is outward extended with a fixed foot portion 41, this electroconductive elastic sheet 3 is suppressed in the bottom of this fixed foot portion 41, and these fixed foot portion 41 lateral borders are resisted against sidewall 12 inner edges of this pedestal, these fixed foot portion 41 lateral borders are equipped with a projection 42 again, and this projection 42 protrudes in the groove 121 of this sidewall 12.
The top 123 of this pedestal 1 sidewall 12 imposes the technology of ultrasonic waves or other plastic deformation processing, makes it be bent to form a kink 123B inwardly and suppresses this projection 42 that stretches in this groove 121, breaks away from these pedestals 1 to avoid this button 4.
The groove 121 of this pedestal 1 includes a bottom surface 122 and a side 124, and this bottom surface 122 and this side 124 form a compression face, and this projection 42 that stretches into this groove 121 is promptly born by this bottom surface 122 and this side 124 by this kink 123B squeezing pressure.Make with the soft plastic of silica gel with this projection 42 in addition because of this button 4 and extended fixed foot portion 41 thereof, it is subjected to produce after the extruding of this kink 123B distortion, and then can be resisted against the inner edge of this sidewall 12 and this groove 121 more closely, simultaneously extruded this projection 42 also can be out of shape towards the corner of these groove 121 inner edges, and can fill up the corner of this groove 121.
According to the utility model, these sidewall 12 inner edges are arranged with the design of this groove 121, can make projection 42 distortion of this fixed foot portion made from flexible material and fill up this groove 121, to be resisted against this sidewall 12 more closely, dwindle the slit of 12 of this fixed foot portion 41 and this projection 42 and this sidewalls simultaneously, to reach better waterproof effect.
