And the seven figures are shown. In the implementation, in the general ON state of the sixth figure, referring to the fourth A and B diagrams, the current passes through the first contact terminal 30, the conductive elastic piece 40, the first contact 41, the second contact 311, The second contact terminal 31 forms an energized (ON) state in which a normal current is conducted. At this time, although the indicator light 50 is displaced downward, the free end 551 φ of the connecting member 55 of the second pin 52 is kept in contact with the lower end of the extending portion 312' of the second contact terminal 31, and the circuit circuit of the indicator light 50 is still connected. State, but since the current is almost completely flowing " to the normal circuit loop, the current in the circuit loop of the indicator light 50 is driven close to zero and the indicator light 50 does not illuminate. In the seventh diagram, when the current is overloaded or the environment is overheated, the circuit of the normal current trips to a state of being turned off (OFF), which is the same as the fifth and fourth diagrams. At this time, the indicator light 50 is displaced upward, and the free end 551 of the connecting member 55 at the lower end of the second pin 52 of the indicator light 50 is in contact with the upper end of the extending portion 312' of the second contact terminal 31, and the current is passed through the first contact terminal 30. The extension end 541, the elastic member (compression spring) 54, the resistor 53, the first pin 51, the indicator light 50, the second pin 52, the connecting member 55, the free end 551, the extending portion 312, and the second contact terminal 31 Forming a power-on state of a weak current circuit, the weak current turns on the circuit circuit of the indicator lamp 50, the indicator light 50 emits light, and transmits light through the button 20, indicating that the corresponding normal circuit circuit is in an abnormal state of power-off (OFF) . Referring again to the eighth and ninth drawings, it is the third embodiment of the present invention. Wherein, the 11th 201025775 - 8th diagram is a normal current energization (ON) state and the cross-sectional view of the button 20 is not drawn; the ninth diagram is a normal current power off (OFF) and the cross-sectional view of the button 20 is not drawn, and the indicator light 50 light state. The constituent elements of the third embodiment are almost the same as the foregoing embodiments (first to third figures), and the difference is that the lower end of the second pin 52' of the indicator light 50 of the third embodiment is fixedly connected and electrically connected to the second contact terminal. 31. In a specific implementation, in order not to affect the up and down operation of the button 20 or the indicator light 50, the second pin 52' of the third embodiment is a soft conductive wire body, and the φ soft conductive wire body is easy to follow. Bent material. In the present embodiment, the lower end of the second pin 52' is directly soldered to the extended portion 312 of the contact terminal 31. - The third embodiment is the same as the operation and principle of the foregoing second embodiment. The indicator circuit 50 is the same as the power circuit (ON) state of the circuit circuit in the normal state or the power failure (OFF) state during the current overload or the environment overheating. The two pins 52' remain electrically connected to the second contact terminal 31, so that the circuit circuit of the indicator light 50 remains in communication. ^ In the energized (ON) state of the eighth diagram, since the current flows almost completely to the normal circuit loop, the current in the circuit loop of the indicator light 50 is driven to zero, and the indicator light 50 does not emit light. In the ninth figure, when the current overload or the environment is overheated, the circuit circuit of the normal current trips to a state of being turned off (OFF), the indicator light 50 is moved up, and the second pin 52' of the indicator light 50 is pulled upward. However, the lower end of the second pin 52' is kept connected to the extending portion 312 of the second contact terminal 31, and the current is passed through the first contact terminal 30, the extended end 541, the elastic member (compression spring) 54, the resistor 53, the first pin 51, The indicator light 50, the second pin 12 201025775 - 52', the extension portion 312, and the second contact terminal 31 form an energized state of a weak current circuit, whereby the weak current turns on the circuit circuit of the indicator light 50, and the indicator light 50 emits light. The corresponding normal circuit loop is displayed as an abnormal state of power-off (OFF). Referring to the tenth figure, it is a perspective exploded view of the fourth embodiment of the present invention. In the fourth embodiment, a third terminal slot 16 is disposed in the casing 10, and the extension portion 312 of the second contact terminal 31 of the foregoing embodiment is removed. φ is further provided with a third contact terminal 32. The third contact terminal 32 is further provided. The second contact terminal 32 is not in contact with the second contact terminal; the third contact terminal 32 is received in the third terminal slot '16, and the outer end of the third contact terminal 32 protrudes from the case 10. - In the implementation, reference is made to the eleventh figure for a cross-sectional view of the energized (ON) state of the undrawn button 20 of the fourth embodiment. The operation is the same as in the previous embodiment, and the fourth and fourth B diagrams are in a normal energized (ON) state. At this time, the circuit circuit of the indicator light 50 is open, and the indicator light 50 does not emit light. When the current is overloaded or the environment is overheated, referring to Fig. 12, the circuit loop φ is turned off to be in an OFF state, which is the same as the fifth and fifth B diagrams of the foregoing embodiment. At this time, the indicator light 50 is displaced upward, and the free end 551 of the connector 55 at the lower end of the second pin 52 of the indicator light 50 is in contact with the third contact terminal 32, and the current is transmitted through the first contact terminal 30 and the extended end 54 to the elastic member ( a compression spring 54 , a resistor 53 , a first pin 51 , an indicator light 50 , a second pin 52 , a connector 55 , a free end 551 , and a third contact terminal 32 form a weak current energization state, thereby being weak The circuit of the current conduction indicator lamp 50 is illuminated by the energization state, and the abnormal state of the normal circuit circuit is displayed. 13 201025775 - Embodiment 4, mainly in that a third contact terminal 32 is provided, so that the circuit loop connecting the indicator light 50 is a current from the first contact terminal 30 to the third contact terminal 32, and the normal state of the normal energization (ON) state The normal circuit circuit of the current from the first contact terminal 30 to the second contact terminal 31 is different. The fourth embodiment is mainly to completely separate the current of the normal circuit circuit of the power failure and the trip state from the indicator light 50 of the abnormal state to ensure the safety of the electric power, and is more suitable for the tripping or powering off of the electrical equipment using the small current or Display of other abnormal states. ❹ As described in the above embodiment, the present invention is in the normal normal (ON) state, the indicator light 20 is not energized or illuminates; when the current is overloaded or the environment is overheated, the free end of the conductive elastic piece 40 trips, so that the normal circuit circuit The power is turned off (OFF) to ensure safe use of electricity. At the same time, the indicator light 20 is illuminated by connecting a circuit circuit of a weak current to achieve an abnormal state in which the normal circuit circuit is powered off. _ From the above, the present invention has practical effects, and is a new design that has never been seen before, and has efficacy and progress.
