Embodiment
Please be simultaneously with reference to Fig. 2 A, Fig. 2 B and Fig. 2 C, Fig. 2 A illustrates the circuit board stereogram.Fig. 2 B illustrates the circuit block diagram of a preferred embodiment.Fig. 2 C illustrates the button stereogram.Circuit board 200 comprises a body 202 and a switch 201.Switch 201 is arranged on the body 202.Switch 201 comprises: a housing 203, button 204, several pins and a light-emitting diode 207.Several pins for example are the first pin 208a, the second pin 208b, the 3rd pin 208c and the 4th pin 208d.The first pin 208a and the second pin 208b are the welding foot that is welded in circuit board 200.The 3rd pin 208c and the 4th pin 208d are the pin of light-emitting diode 207.
Please refer to Fig. 2 B, button 204 comprises first make contact 204a, the second contact point 204b, the 3rd contact point 204c and the 4th contact point 204d.First make contact 204a, in order to be electrically connected the first electric contact 210a, the second contact point 204b is in order to be electrically connected the second electric contact 210b.And the 3rd contact point 204c and the 4th contact point 204d are in order to be electrically connected with the 3rd electric contact 210c and the 4th electric contact 210d respectively.
In addition, the 3rd electric contact 210c connects an end (anode) of light-emitting diode 207, and the other end of light-emitting diode 207 (negative terminal) connects the 3rd pin 208c.The 4th electric contact 210d connects the 4th pin 208d, and the 4th pin 208d connects the VCC power supply of a high potential.When the 3rd electric contact 210c was not electrically connected the 4th electric contact 210d, light-emitting diode 207 two ends were open circuit, so light-emitting diode 207 does not have electric current to flow into and can be not shinny.And when being electrically connected the 3rd electric contact 210c and the 4th electric contact 210d that is during pressing button, the first electric contact 210a and the second electric contact 210b are short circuits, the 3rd electric contact 210c and the 4th electric contact 210d also are short circuit simultaneously, light-emitting diode 207 two ends produce pressure drop, therefore electric current can pass through the ground plane of light-emitting diode 207 to electronegative potential from the VCC power supply 206 of high potential, and makes light-emitting diode 207 produce light.
For housing 203 or button 204, can make transparence, for example be transparent acryl.Therefore when light-emitting diode 207 produces light, light can be through transparent housing or button to inform the user, and whether electronic installation is activated.And the first pin 208a, the second pin 208b, the 3rd pin 208c and the 4th pin 208d be metal material for example for the copper metal made, to be electrically connected with signal receiving end 205 or VCC power supply 206.Such practice need not be electrically connected VCC power supply 206 and control circuit 209, makes pressing button 204 to start the carrying out that electronic installation and light-emitting diode 207 can be synchronous.
When pressing button 204 once more, the first electric contact 210a and the second electric contact 210b become once again and open circuit, and the 3rd electric contact 210c and the 4th electric contact 210d also form and open circuit and powered-down.
The disclosed switch of the above embodiment of the present invention is arranged at light-emitting diode in the switch.When opening switch, the while is the conducting light-emitting diode also, so has the function of drive electronics and generation light in the switch simultaneously concurrently.Saving the space that light-emitting diode and switch separate configuration are wasted, and make circuit board more space be arranged as other purposes.Especially present many electronic products are all done littler and littler, and such switch will be suitable in these a little electronic products very much.
In sum; though disclosed the present invention in conjunction with an above preferred embodiment; yet it is not in order to limit the present invention; anyly be familiar with this operator; without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, so protection scope of the present invention should be with being as the criterion that claim was defined.
