Also, The front end of the secondary winding leg is installed with ί: ϊ = 2 double-layer winding coils, as shown in FIG. 28, which is first installed, wood # ', _ 人' and welded the support plate 22 to the -end of the -secondary winding 202 The slit f Iff is inserted into the other end, and it is completed. _ Double-layer winding coil, because the fj winding 203 series double-layer winding is contained inside the core 201, which has the problem of poor heat dissipation and easy to generate heat. Thin 9nft coil Each winding is wound at a different position on the core of the sweet-like core. Secrets such as amorphous magnetic materials or; i :: soft m. In this way, the output current of the secondary winding can be increased, and m redundant. Increase in the degree. By comparing the currents of the equal wheels, the ring-shaped coil group coils are smaller. And because the secondary winding and the secondary winding i ^ can be reduced, the heat dissipation of the winding can be improved. The stay of less heat suppresses the rise of the internal temperature. Next, the operation of the switch sw with a display lamp will be described. The switch sw is shown in Figure 2005a (2005) (a), the power supply (such as a commercial power supply) E, and the lamp (load) L series. It is connected in series to the terminals A and A of the pair. When the switching section 6 is set to 0N (closed), a current ML in the primary winding 200 of the converter 20 is activated (lighted) through the lamp L. At this time, based on the current When the current is measured in the secondary winding, the light-emitting diode (LED) 41 is lit. From this state, the switching section 6 is turned OFF (the fluorescent lamp 43 is lit when it is turned on, and there is almost no current flowing in the primary winding 202). Therefore, the lamp l goes out. Along with this, there is almost no current flowing in the secondary winding 203, and the LED 41 goes out. From the above-mentioned action, the operating state of the lamp L can be easily identified on the switch sw. Fig. 29 (b) shows a circuit when two switches sw with a display lamp are used.

However, when the lamp L is a low load, the induced voltage on the secondary winding 203 side is small, and the current cannot be sufficient. In order to solve the above-mentioned problem, when the secondary winding 202 is 1 load higher than the lamp L, the temperature of the inverter 20 itself rises, which causes another problem that the switch SW with no display lamp cannot be used. The ancient road determination method has a method of increasing the magnetic permeability of the magnetic core relative to the magnetic field strength. The method also allows the secondary winding 202 to flow through a small number of turns in the primary winding 202.

These switches SW are exchanged on the same side (upper or lower side in FIG. 9 (b)) when the switches 6 are turned on, and a current flows and the lamp 1 lights up, and at the same time, the LED 41 also lights up. From this state, if any one of the switching sections 6 is exchanged to a different side (upper side to lower side, or lower side to upper side), the lamp L is turned off, and at the same time, the LED 41 is also turned off. With such a structure, for example, by setting switches sw in each of the separated spaces, it is possible to control the lamp L from an individual place to recognize the operation state. Furthermore, in the modified example of Embodiment 6 or 7, as shown in Figs. 11 or 16, a diode bridge 70 may be used instead of the converter 20. The structure of the switch SW is as shown in FIG. 12 (a) in the sixth embodiment, as shown in FIG. 18 in the seventh embodiment, and the diode block 7 is as shown in FIG. 11 or 12 (b). Insert molding. (Embodiment 8) Embodiment 8 is provided with converter 20, switching section 6, and LED 41 as in embodiment 6, but what is absent from embodiment 6 is a characteristic part described below. As shown in Figure 19, a reverse counter-resistance resistor 47 is connected in parallel to the LED 41 and the LED protection resistor 46 on the secondary winding 203 side of the converter 20, regardless of the size of the lamp (load), and it is in the converter current. 16 of the transformer 20 200522091 When the high-frequency component current flows in the primary winding 202, the LED is 41 points old. The converter 20 uses a core with a very high magnetic permeability (not shown) to form the number of windings of the secondary winding 202 Less, the current value of the lamp (load) L is low, and the induced voltage on the secondary winding 203 side of the converter can be high, which can increase the current amplitude corresponding to the load current by 7 *% from the switch connected to the display lamp (page 19 ("Switch B") of the lamp (load) L contains high-frequency components such as reverse ϋ current as the secondary power through the primary winding 202, on the secondary winding 203 side, counter-resistance resistance The resistance value of the device 47 is too high. In this way, the magnetic flux of the core generated by the secondary current of the secondary winding 202 is eliminated, the total magnetic flux of the core is reduced, and the magnetic saturation of the core can be prevented. In this way, a large current can flow through the LED 41, and the LED 41 can be used as a two-way lighting fixture, as shown in Figure 20 (a). The relationship between the _ value of the secondary winding S03 4m to the counter current resistor 47 on the secondary winding and the voltage induced voltage on the reverse reactance terminal i is explained below. The 20th counter current resistor 47 is connected to the secondary winding 203 Side, such as the 19th two-body /,-using the protective resistor 46 and 1 reverse counter current ii ° LFD ί when f is connected to the circuit of Figure 20, the induced voltage is applied to the above LED 41, two poles The body 42, Lm) uses a protective resistor 46. Inductive Ϊ1 ° diagram = pair ==== two resistance values, vertical ⑽47 of € & 4 small _ should be high when the electric voltage is 1, the induced voltage is low. Only the resistance value is 15kΩ, the total voltage is 4 and the counter current voltage is not connected to the reverse iimrfIf voltage. When the resistance value is 15k ohms, it is different when the load is 22. The resistance value is the threshold voltage required for 15k ohms to light. The peak voltage of LED 41 u can exceed the LED41. The peak voltage does not exceed: 3 required for 41 °. In contrast to this, when there is no load, such as flute ^ Threshold voltage 'can't light up 4 P, and the value is small, then LED 41 41' 'Reverse counter-balance resistor 47's magic rule 41 41____ is lost, otherwise, the resistance value is large 17 200522091 flows through LED 41 The current is small and the brightness is low. And because the resistance value is small, the loss increases. Considering the above item, the resistance value of the reverse counter-resistance resistor 47 must be set. In this way, when the inverse counter-resistance resistor 47 is connected in parallel with the LED 41 on the secondary winding 203 side, the induced voltage can be larger than that of the non-loaded one. General converters that do not use high-permeability cores, because the cores cannot afford magnetic saturation, the maximum induced voltage is at no load. When the lamp (load) L is an ordinary incandescent lamp, the resistance and value of the reverse counter-resistance resistor 47 is about 30 times to 50 times the value of the protection resistor 46 for LEDs connected in series with the LED 41. With a slight current, the light emitting characteristics of the LED 41 are not deteriorated. Fig. 21 (a) is a side view of a switch with a display lamp, and Fig. 21 (b) is an exploded side view. The case 1 includes a current conversion block 2, a pair of primary-side terminal portions 3, a photographic block 4, a middle frame 5, and an opening / closing element block 65. In the one-to-one primary terminal portion 3, a terminal portion 34a is provided in the primary terminal portion 3a, and a terminal portion 34b is provided in the primary terminal portion 3b. The lock springs 31a and 31b and the terminal portions 34a and 34b constitute a quick-knot terminal. The terminal portions 34a and 34b are also provided with contacts for opening and closing the load circuit. The cover u is provided with a handle portion (not shown) that causes the opening-closing operation to be performed by a switching operation (not shown), and an opening-closing element block 65 is provided for opening and closing the load current. The converter block 2 includes a converter 20 (refer to FIG. 19), and a primary current flowing through the primary winding 202 generates an induced voltage on the secondary winding 203 (refer to FIG. 19). (See Figure 19) Lights up. Illumination block 4, as shown in Fig. 22 (a), on one side of a printed circuit board (for B (single-sided)) 40. 'LED 41, diode which lights the lamp (load) L in the ON state. 42. The LED protective resistor 46 and the reverse counter-resistance resistor 47 are mounted by, for example, soldering. On the other side, a contact 45 is mounted by, for example, soldering or the like. Since the lighting block 4 is connected to the terminal portion 34b (see FIG. 21) by, for example, soldering, the connection with the terminal portion 34b is highly reliable. Although FIG. 19 is not shown, a fluorescent lamp 43 that can be spotted when the lamp (load) is in the 0FF state can be installed, and a protective resistor 44 for fluorescent lamps can also be installed. As described above, according to Embodiment 8, the reverse counter-resistance resistor 47 connected in parallel with the LED 41 and the like is connected to the secondary winding 203 side of the converter 20, the total magnetic flux of the core is reduced, and the lamp (load) L is infinite. The lamp L can light the led 41 smoothly. 200522091 The modified example of the embodiment 8 may replace the reverse balancing resistor 47. As shown in FIG. 23, the reverse balancing capacitor 48 may be connected. The lighting block 4 is the same as the lighting block 4 of Embodiment 8 except that the reverse balancing resistor 47 is replaced with a reverse balancing capacitor 48 as shown in FIG. 22 (c). With such a structure, the larger the capacitance of the reverse countercapacitor 48 is, the magnetic saturation of the core can be avoided by the current flowing through the reverse countercapacitor 48, and the effect as in Embodiment 8 can be obtained. When the voltage on the secondary winding 203 side is low A large current may flow. In the case of the reverse counter-resistor 47, the current is limited because the resistance value is still low when the voltage on the secondary winding 203 side is low. In the modification of the eighth embodiment, as shown in Fig. 24, each of the reverse balancing resistor 47 and the reverse balancing capacitor 48 may be connected in parallel. The lighting block 4 is the same as the lighting block 4 of the eighth embodiment except that a reverse counter capacitor 48 is installed as shown in FIG. 22 (b). With this structure, the magnetic saturation of the core can be prevented from being caused by the current flowing through the reverse counter-capacitor 48, and the effects of both when the reverse-counter resistor 47 is connected and when the reverse-counter-capacitor 48 is connected can be obtained. (Embodiment 9) Embodiment 9 is provided with converter 20, switching section 6, and LED 41 as in Embodiment 6, and the features not included in Embodiment 6 are the following characteristic parts. As shown in Figure 25 (a) and Figure 26 (a), the rated current is, for example, a switch of 4 amps with a display lamp, connected in series with the primary winding 202 of the converter 20, and a resistor 49 with a low resistance value is connected. Blocks the circuit when a current exceeding the rated current flows. The resistor 49 is, for example, an allowable power value of about 1/4 watt and a resistance value of 0.001 ohm or less. In addition, the resistor 49 may be a jumper chip resistor using a resistor combining the above-mentioned allowable power value. When the resistor 49 has, for example, a current of about 4 amps flowing, the loss of the resistor 49 is about 160 watts, which does not exceed the allowable power value, and the resistor 4g is disconnected (blocked). In contrast, when a current of about 100 amps flows, the loss of the resistor 49 is about 100 watts. When the allowable power value is exceeded, the resistor 49 is disconnected, so that the circuit can be safely blocked. Above, according to the embodiment 9, when a current exceeding the rated current flows, the resistor 49 is disconnected when the allowable power value is greatly exceeded, the circuit can be blocked, and the temperature of the switch with the display lamp 19 200522091 can be prevented from rising. To protect the switch with indicator light. Secondly, the modified example of the embodiment 9 may replace the current transformer 20, as shown in FIG. 25 (b), and a diode bridge 70 may be installed. As shown in Fig. 27 (a), a resistor 49 is installed in series with the diode block 7 and the diode bridge 70. As shown in Fig. 27 (b), a middle frame 5 is installed. The diode bridge is a switch equipped with a display lamp, and its rated current is smaller than that of a switch equipped with a current transformer 20 (for example, 0.5 amps). The diode bridge 70 uses a diode. The voltage of 70a to 70e drops, and a voltage is generated at the two ends to light up LEd 41. With this structure, when a current exceeding the rated current flows, the effect similar to that of the X-shaped Bear 9 can be obtained. Another modification of the ninth embodiment may replace the diode 70e of the diode bridge, as shown in FIG. 26 (b), and a resistor 49 may be provided. A resistor 700 and a capacitor 701 are provided in series with the LED 41 and the diode 42. The capacitor 701 is provided for boosting the voltage obtained by the diode. With such a structure, the effect similar to that of Embodiment 9 can also be obtained when there is a current exceeding the rated current; Machine V.
