Adopt the design of said structure, the shape of traditional light source and light-receiving device is replaced with sheet, in order to solve photophore and light-receiving device light conduction, realize the function of photoelectric coupling, the utility model introduces the first light guide and the second light guide, by the effect of above-mentioned light guide, by the elevated height in the path that the light-receiving device of sheet and source light conduct, well can either realize the disconnected conjunction of light path, also can solve the restriction of photophore and light-receiving device height, make the keyboard of button, installation button more frivolous.
In the utility model, preferred scheme is that described first light guide comprises the first light inputting end and the first bright dipping end, described second light guide comprises the second light inputting end and the second bright dipping end, described light source emit beam from the first light inputting end of the first light guide enter, the first bright dipping end passes; The light injected on the second light guide enters from the second light inputting end, the second bright dipping end passes, and the light passed from the second bright dipping end is radiated at light-receiving device.
In the utility model, preferred scheme for described in be provided with shadow shield by the outer wall of axle, be provided with the gap can passed through for shadow shield between described first bright dipping end and the second bright dipping end; When by axle when nature (pressing axle in nature in the utility model, refer to the state do not stressed by axle), the light barrier that the first bright dipping end passes by shadow shield; When pressing down by axle is stressed, the light that the first bright dipping end passes enters the second light guide from the second light inputting end.The design of this structure, when pressing axle in nature, shadow shield is between the first bright dipping end and the second light inputting end, and the light path of optoelectronic switch disconnected, namely optoelectronic switch is in off-state; When pressing down by axle is stressed, shadow shield down moves with by axle, no longer blocks the light path between the first bright dipping end and the second light inputting end, and the light that now the first bright dipping end passes enters the second light guide from the second light inputting end, the optical circuit of optoelectronic switch, namely optoelectronic switch is in closure state; When not stressing by axle, shadow shield gets back to origin-location, the light path of optoelectronic switch is disconnected; Can be good at the disconnected conjunction function realizing light path.
In the utility model, preferred scheme is that described first bright dipping end and the second light inputting end are arranged face-to-face.
In the utility model, preferred scheme for described in be provided with reflector by the outer wall of axle; When pressing axle in nature, the light of the first bright dipping end can not enter the second light inputting end; When pressing down by axle is stressed, the light that the first bright dipping end passes enters the second light inputting end after reflector reflection.The design of this structure, when pressing axle in nature, the light of the first bright dipping end can not enter the second light inputting end; The light path of optoelectronic switch disconnected, namely optoelectronic switch is in off-state; When pressing down by axle is stressed, reflector down moves with by axle, the light that first bright dipping end passes enters the second light inputting end after reflector reflection, the light that now the first bright dipping end passes enters the second light guide from the second light inputting end, the optical circuit of optoelectronic switch, namely optoelectronic switch is in closure state; When not stressing by axle, origin-location got back to by reflector, the light path of optoelectronic switch disconnected; Can be good at the disconnected conjunction function realizing light path.
In the utility model, preferred scheme is that described first bright dipping end and the equal vertical plane of the second light inputting end are to the outer wall being provided with reflector by axle.
In the utility model, preferred scheme is that described base is provided with spring, described in be provided with cylinder by axle lower surface, described spring housing is established on the cylinder.
In the utility model, the preferred scheme one that to be described light-receiving device be in the light-sensitive devices such as photo resistance, photodiode, phototriode.
In the utility model, preferred scheme is described light source is LED.
Compared to existing technology, the beneficial effects of the utility model are: the design adopting said structure, the shape of traditional light source and light-receiving device is replaced with sheet, in order to solve photophore and light-receiving device light conduction, realize the function of photoelectric coupling, the utility model introduces the first light guide and the second light guide, by the effect of above-mentioned light guide, by the elevated height in the path that the light-receiving device of sheet and source light conduct, well can either realize the disconnected conjunction of light path, also the restriction of photophore and light-receiving device height can be solved, make button, the keyboard installing button is more frivolous.
