DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The pilot lamp lighting switch of the present embodiment comprises a switch main body 2 shown in FIG. 2 and a pilot lamp 3 lighting means 4 incorporated therein. First, the switch body 2
Has a size of one standardized wiring device module, and is composed of a synthetic resin cover 5 and a body 6 that form an outer shell, and are connected to each other by a pair of assembly frames 7. Here, the body 6 is divided into a pair of left and right connection terminal housings 10 and 11 and a printed circuit board housing 12 by a rib 9 made of an insulating material. The contact terminal block 13 and the lock spring 1 are provided in one of the connection terminal housings 10.

The connection terminal portion made of is housed. A support plate 19 electrically connected to the terminal plate 16 is arranged at the bottom of the body 6, and a substantially U-shaped opening / closing body 8 is swingably arranged on a protrusion 20 formed on the support plate 19. Has been done. A reversing mechanism configured to reversely drive the opening / closing body 8 includes a coil spring 21, a reversing handle 22 and the like, and an operator 23 protruding from the lower surface of the reversing handle 22 contacts the upper end of the opening / closing body 8 to invert. The opening / closing body 8 is caused to perform a seesaw operation by the reversing operation of the handle 22 to open / close the contacts 26, 27. In FIG. 2, 64 is a card cover.

The pair of assembly frames 7 have locking claws 85 for connecting the cover 5 and the body 6 formed to project downward, and a plurality of claws 30 formed to project laterally. The claw 30 has a structure in which it is removably engaged with a standardized synthetic resin mounting frame 31 shown in FIG. That is, of the pair of assembly frames 7, the claw 30 of one of the assembly frames 7 is inserted into the notch hole 33 provided on the side of the side frame side 32 of the mounting frame 31 to be fitted into the projecting hole 34 so as to project upward from below. At the same time, the claw 30 of the other assembly frame 7 is attached to the bending piece 35 of the mounting frame 31.
When the claw 30 reaches the shoulder 37, the bending piece 35 returns to its original state due to its spring property, so that the switch body 2 is assembled. It is integrally attached to the attachment frame 31 via the frame 7. It should be noted that when detaching, the operation reverse to the above may be performed.

On the other hand, the lighting means 4, as shown in FIG.

It is an electric wire.

Next, the operation of the lighting means 4 will be described. Figure 4
When the switch SW shown in is ON, the diodes D _{1 to} D
_{Since 5} is an AC power supply, current flows through the diode D ₁ → D ₅ → D ₃ → load L in the positive half cycle of the AC power supply, and load L → diode D _{4 in} the negative half cycle of the AC power supply.
The current flows from → D ₅ → D ₂ . And the diode D
_Since the voltage drop of _{1 to} D ₅ is almost unaffected by the magnitude of the load current, a constant potential difference is always generated between a and b. Therefore, the potential difference between a and b supplies a substantially constant current to the light emitting diodes LED ₁ and LED ₂ , and therefore the light emitting diodes LED ₁ and LE.
The brightness of D ₂ does not change so much and becomes a substantially constant brightness. The forward voltage drop per diode is about 0.7 V, and the light emitting diode L
ED _1, the forward voltage drop of the LED ₂ is about 1.8V in the case of gallium phosphide device eg for about 1.5V in the case of gallium aluminum arsenide devices, light emitting diodes LED _1, LED the current flow in the ₂ becomes necessary series connection of three diodes, in this embodiment, when connecting the diodes D ₁ to D ₅ as shown in FIG. 4, regardless of the direction of the load current, the diode to flow in the same direction of the current in D _5, the diode D ₁ to D ₅ are total of five may be.

In the case of a switch with a built-in semiconductor, the element breaks down due to factors such as an inrush current when the power is turned on, an induced lightning surge induced in the power line, and electrostatic discharge received by a person during operation, resulting in non-conduction. It is possible that FIG. 5 is FIG.
Shows the current waveform of each diode D ₁ to D ₅ of the circuit of the FIG. (A) is the load current, FIG. (B) is a diode D _1,
The current of D _3, FIG. (C) is a current of the diode D _2, D _3, FIG irradiation shows the current of the diode D _5, respectively. The diode D _5, compared to other diodes D ₁ to D ₄ current flows only one side of the half-cycle, a current flows over both half cycles, the probability of the diode D ₅ is failing nonconductive high. When the diode D ₅ becomes non-conductive, the entire rectifying block A becomes non-conductive, and the load current all flows to the display block B. This is because the load current is the pilot lamp 3 (light emitting diode LE
The lighting switch 1 can be used without failure as long as it is within the rating of D ₁ , LED ₂ ), but if it is above the rating, the pilot lamp 3 fails and the lighting switch 1 becomes non-conductive. Here, in the case of a circuit in which a plurality of diodes are simply connected in series and parallel, the probability that all the diodes D _{1 to} D ₅ fail is constant, and the diode D ₁ fails, and the load current is equal to or higher than the rating of the pilot lamp 3. Then, when the pilot lamp 3 fails, a half-wave rectified current flows in the circuit. Since the rated current of the pilot lamp 3 is as small as several tens of mA, the load current is more than the rated current in most cases. In such a state, the load L is adversely affected, and in the worst case, the load L may be broken or burned, which is dangerous. However, with the circuit configuration shown in FIG. 5 of the present invention, as described above, there is a high probability that the entire lighting switch 1 will become non-conductive, and the failure will occur in a safe mode.

In the above structure, the four diodes D interposed between the pilot lamp 3 and the switch section SW.
_By connecting _{1 to} D ₄ in a bridge shape and integrating them as one diode bridge D, the number of parts of the lighting means 4 is reduced, and therefore, even if the printed circuit board 50 is narrow, one diode bridge D is provided. Since one diode D ₅ , one resistor R, and the pilot lamp 3 can be connected to each other with a sufficient insulation distance, soldering is facilitated and assembly is improved. Moreover, the position of the lead wire connecting portion 40a connected to the first printed circuit board 51 is set at a position away from the pilot lamp 3 and the connecting portions 40a are separated from each other, as shown in FIG. Since the distance E between the bilot lamp 3 and each lead wire connecting portion 40a can be widened, the insulation distance is increased and the safety can be improved. Besides,
By reducing the number of parts, the lighting means 4 can be provided on the narrow printed circuit board 50. As a result, the lighting means 4 can be easily and safely incorporated into the switch body 2 having the size of one wiring fixture module. There are advantages. In addition, the nail 30 is attached to the assembly frame 7 of the switch body 2.
Since the claw 30 is detachably engaged with the standardized mounting frame 31, the mounting work of the switch main body 2 on the standardized mounting frame 31 is facilitated and the work can be further improved. There is an advantage.

Next, in forming the first printed circuit board 51 and the second printed circuit board 52, a conventional method is shown in FIG.
As shown in FIG. 1, a large number of first printed boards 51 are formed on one type of printed circuit board, and a large number of second printed circuit boards 52 are formed on another type of printed circuit board. Mount the mounting components (pilot lamps) on the first printed circuit board 51 separated from each other, and
After mounting the mounting components (diodes, resistors) on the printed circuit board 52, the first printed circuit board 51 and the second printed circuit board 52 are electrically connected via a plurality of lead wires 40 (FIG. 8). Was doing. Therefore, it is necessary to perform a multi-piece of the first printed board 51 and the multi-piece of the second printed circuit board 52 in separate, yet mounting of mounting parts, such as pilot lights 3 and the diode D ₁ to D ₅ In addition, the steps are separated, and furthermore, the connection of the lead wire 40 can be performed only after dividing the first printed board 51 and the second printed board 52 into individual units. The work of connecting the lead wires 40 is also troublesome because it is necessary to position the first printed board 51 and the second printed board 52.

On the other hand, in this embodiment, as shown in FIG. 6A, a first printed board 51 and a second printed board 52 adjacent to the first printed board 51 are provided on one type of printed board. A large number of sets are integrally formed so that each set can be separated. That is, by arranging a large number of shapes of the first printed circuit board 51 and the second printed circuit board 52 on one printed circuit board, mounting components such as pilot lamps and diodes are mounted on the first printed circuit board 51 and the second printed circuit board 52. The printed circuit board 52 can be collectively inserted and soldered in a connected state. Moreover, as shown in FIG. 6B, the lead wire 40 connecting the first printed board 51 and the second printed board 52 is also connected to the first printed board 51 and the second printed board 52. This makes it easy to divide each set and carry out a large number of sets. Further, since it is not necessary to position the first printed circuit board 51 and the second printed circuit board 52 when connecting the lead wire 40, the work of connecting the lead wire 40 becomes simple.
After that, for the first time, a large number of the first printed circuit board 51 and the second printed circuit board 52 are taken along the imaginary line M, and one set of the first printed circuit board 51 and the second printed circuit board 52 is set. When used in the same product, it can be handled as one set, and as a result, the printed circuit board 50 can be rationalized and the assembling property can be further improved. Figure 6
The reference numeral 90 designates a crosspiece which is attached so as to enable automatic soldering, and is removed when a large number of printed circuit boards are taken.

By the way, conventionally, the connecting electric wire connected to the outside of the printed circuit board is composed of two electric wires 48 'and 49' as shown in FIG.
If each 49 'is short, it becomes difficult to solder, and the wire 4
There is a problem that 8 ', 49' becomes difficult to handle.
Therefore, in the present invention, as shown in FIG. 7A, the electric wire for connection with the outside of the printed wiring board 51 is preliminarily constituted by one long single wire 80, and the portion of the single wire 80 without the covering 81 is divided. Thus, as shown in FIG. 7B, one single wire 80 is divided into two short electric wires 48, 49 so that they can be connected to different terminals (not shown). In this way, by dividing one long single wire 80 into two electric wires 48 and 49, the number of parts of the electric wire can be small, and even a short electric wire can be handled easily, so There is an advantage that the efficiency of the soldering process of the connection electric wire can be improved.
