  The switch device 1 is constituted by the above-described members, and the assembly method will be described next. First, the intermediate frame 20 is fitted to the transformer block 4, and each end of the intermediate frame 20 is fitted with one end N1a of the primary winding N1 of the current transformer CT protruding forward from the insertion hole 20e of the intermediate frame 20. The protrusions are attached by being concavo-convexly fitted into the respective fitting recesses 40 a of the case 40 of the transformer block 4. Thereafter, the flat plate portion 21a of the support plate 21 is placed on the front surface of the base portion 20a of the middle frame 20, and the other end N1b of the primary winding N1 is soldered to the coil connection portion 21b of the support plate 21.

Then, with the transformer block 4 to which the inner frame 20 and the support plate 21 are attached in this way, with the distal end portions 41a, 41a of the connection portions 41, 41 facing forward, the center in the longitudinal direction of the bottom wall portion of the body 60 Store in the recess of the part.

  Next, the two release buttons 33 are respectively stored in the body 60 so that the operation portion 33a faces the outside of the body 60 from each jig insertion hole of the body 60, and the three lock springs 32 are connected to the lock pieces. 32 a is stored in the body 60 so as to face the pressing piece 33 b of the release button 33 and to face each insertion hole of the body 60.

  Then, the power supply terminal plate 30 is mounted on the support portion 20b of the middle frame 20 so that the pair of pressing pieces 30c, 30c of the power supply terminal portion 30a and the feed terminal portion 30b face the lock spring 32.

By being placed on the support portion 20c of the middle frame 20 so as to face the terminal plate 30 side, the terminal body 30 is housed in the body 60. Thereby, terminal part T2 which consists of a quick connection terminal which locks the electric wire inserted from the insertion hole for loads is comprised.

That is, as shown in FIG. 1B, the illumination block 5 is connected to the respective connected portions 58 and 59 of the illumination block 5 by inserting and connecting the distal end portions 41a of the respective connection portions 41 of the transformer block 4, and the power source. The power contact 54a and the load contact 56a of the illumination block 5 are elastically contacted with the terminal plate 30 and the load terminal plate 31, respectively, and are housed in the body 60.

  Here, in the conventional example shown in FIGS. 16A and 16B, it is necessary to solder the illumination block 5 to the transformer block 4 when the illumination block 5 is stored. Since the illumination block 5 can be connected to the transformer block 4 by connection, it is not necessary to perform soldering.

  As shown in FIG. 1B, in the body 60 that houses the illumination block 5, the switch 23 is electrically connected to the flat plate portion 21a of the support plate 21 at the base end portion of the switch 23, and the shaft portion 23b. Are inserted into the bearing portion of the body 60, the shaft portion 23c is inserted into the bearing portion of the rib 20d of the middle frame 20, and the restriction projection 23d is inserted into the restriction groove portion of the rib 20d of the middle frame 20, respectively. A cover 61 is attached to the body 60. Here, the reversing handle 24 is attached to the cover 61 by supporting the shaft portion 24a on the pair of bearing portions 61d of the cover 61, and the push button handle 62 is attached to the cover 61 as described above. A lamp cover 63, a return spring 64, and a slide cam are attached.

  When the cover 61 is attached to the body 60, the front end side of the reversing spring 25 is inserted into the rear end opening of the reversing handle 24, and the rear end edge of the reversing spring 25 is engaged with the engaging protrusion 23a of the switch 23. In this state, the cover 61 is attached to the body 60 by engaging the engaging claws 60a of the body 60 with the engaging holes 61h of the engaging pieces 61g of the cover 61 in this state.

  As a result, the switch device 1 shown in FIG. 8 is obtained. The switch device 1 has a fixed contact 22 and a movable contact, and is electrically connected to the switch mechanism portion SW1 and the fixed contact 22 that move the movable contact to and away from the fixed contact 22. The load terminal plate 31 is a fixed terminal plate to be connected, and the power terminal plate 30 is a movable terminal plate electrically connected to the movable contact. And this switch apparatus 1 is attached to an attachment frame (not shown) using the attachment claws 61i, 61i, and further, a piano handle (not shown) is attached swingably using the shaft portion 61f. In use.

  Next, the operation of the switch device 1 will be briefly described. As shown in FIG. 2, the switch device 1 has one end of the power source AC connected to the terminal portion T1, one end of the load L connected to the other end of the power source AC, and the other end of the load L connected to the terminal portion T2. (Ie, connected in series between the power source AC and the load L).

  In the initial state, the switch mechanism SW1 is turned off (that is, the rear end side of the reversing handle 24 is located close to the power terminal plate 30, and the movable contact of the switch 23 is separated from the fixed contact 22). , A state in which power supply from the power source AC to the load L is not performed). In this initial state, as shown in FIG. 2, a current flows through the electric circuit of the terminal unit T1, the resistor R3, the terminal unit T2, and the electric circuit of the terminal unit T1, the resistor R2, the neon lamp NE, and the terminal unit T2. The neon lamp NE is turned on so that the position of the switch device 1 can be known even in the dark. Of course, when the neon lamp NE is lit, power supply to the load L is insufficient, so that the load L does not operate.

  When the push button handle 62 is pushed from the initial state, the reversing handle 24 is swung by the slide cam (that is, the rear end side of the reversing handle 24 is separated from the power terminal plate 30 and close to the load terminal plate 31). When the reversing handle 24 is swung in this manner, the reversing spring 25 passes through the position where it is compressed most in the middle of the swinging range. Before and after this position, the direction of the spring force acting on the switch 23 from the reversing spring 25 is reversed. Due to the spring force of the reversing spring 25, the switch 23 is swung rapidly, and the movable contact of the switch 23 comes into contact with the fixed contact 22 of the load terminal plate 31, thereby turning on the switch mechanism SW1. Become.

  When the switch mechanism unit SW1 is turned on, a current flows through the electric path of the terminal unit T1, the primary winding N1 of the current transformer CT, the switch mechanism unit SW1, and the terminal unit T2, thereby the load L from the power source. Sufficient electric power is supplied to the load L so that the load L can be operated, and almost no current flows through the neon lamp NE, and the neon lamp NE is turned off. At the same time, an induced electromotive force is generated in the secondary winding N2 of the current transformer CT due to the current flowing in the primary winding N1 of the current transformer CT. On the secondary winding N2 side, the secondary winding N2, the resistor R1, the light emitting diode A current flows through the electric path of the LED and the secondary winding N2, and the light emitting diode LED is turned on. Thereby, it can be visually recognized that power supply to the load L is performed by looking at the switch device 1.

  After that, when the push button handle 62 is pushed again, the reversing handle 24 swings so as to return to the initial state (that is, the rear end side of the reversing handle 24 is separated from the load terminal plate 31 to the power terminal plate 30). As a result, the switch mechanism SW1 is turned off to return to the initial state described above, the load L is turned off, the light emitting diode LED is turned off, and the neon lamp NE is turned on instead. Will do.

  According to the switch device 1 of the present embodiment described above, the secondary winding N2 of the current transformer CT and the illumination block 5 are connected, the connection portion 41 of the transformer block 4 is connected to the connected portions 58 and 59 of the illumination block 5. Therefore, the switch device 1 can be easily assembled. In addition, unlike the conventional switch device shown in FIGS. 16A and 16B, it is not necessary to perform soldering when connecting the secondary winding of the current transformer and the illumination block. It is possible to prevent solder balls, scattering of flux, scorching, poor soldering, deformation due to heat during soldering, short circuit due to solder, and the like. In addition, since it is not necessary to perform time-consuming work such as soldering, it is possible to reduce the time required for assembly, thereby improving the manufacturing cycle time.

  In addition, as shown in FIG. 7 (only the connected part 58 is shown in FIG. 7), the connected parts 58 and 59 of the illumination block 5 bend the first and third lead terminals 51 and 53, respectively. The first spring pieces 51a, 53a, the synthetic resin ribs 57g facing the distal ends P2, Q2 of the first spring pieces 51a, 53a, and the proximal end sides of the first spring pieces 51a, 53a The first and third lead terminals 51 and 53 are bent so as to face the P1 and Q1, and the second spring pieces 51b and 53b are formed.

  As described above, since the respective connected portions 58 and 59 have the ribs 57g made of synthetic resin constituting a part of the connected portions 58 and 59 at the tip side, the lead terminals which are metal plates are bent. Compared with the case where it does, there exists an effect that it becomes easy to produce the shape for to-be-connected parts 58 and 59. FIG. In addition, unlike the spring piece formed by bending the lead terminal, which is a metal plate, the rib 57g is not deformed when the connecting portion 41 is inserted, so that the deformation of the connected portions 58 and 59 can be suppressed. The effect that you can.

  Each of the connected portions 58 and 59 has, on its proximal end side, first spring pieces 51a and 53a and second spring pieces 51b and 53b formed by bending lead terminals 51 and 53 which are metal plates. Therefore, unlike the case of using the synthetic resin ribs 57g, the connected portions 58 and 59 are not deformed by heat, and the heat resistance can be improved.

  Furthermore, since both the first spring pieces 51a and 53a and the second spring pieces 53a and 53b have conductivity, the contact reliability is higher than when one of the ribs 57g is made of synthetic resin. There is an effect of improving the sex. In addition, unlike the synthetic resin rib 57g, there is an effect that creep does not occur.

  By the way, the switch device 1 described above is a one-sided switch device as described above. However, as a switch device, a three-way type device as shown in FIG. Is provided. Such a single-cut type switch device and a three-way type switch device have different circuit configurations and therefore different numbers of parts and shapes, and the conventional one shown in FIGS. 16 (a) and 16 (b). The single-cut switch device 100 and the conventional three-way switch device 200 shown in FIG. 17 use illumination blocks 120 and 220 having different shapes, respectively.

  On the other hand, the illumination block 5 is configured to correspond to a single-sided switch device having the circuit configuration shown in FIG. 2 (having a single-pole single-throw contact configuration) By cutting the lead terminal 54 at the cutting portions indicated by C1 and C2 in FIG. 5A, the circuit configuration shown in FIG. 9 (single-pole switching contact configuration) is also supported.

  The illumination block 5A has the same configuration as that of the illumination block 5 shown in FIG. 5A, but the switch device is a three-way type as shown in FIG. The sixth lead terminals 54 to 56 are different in that they are used to connect the neon lamp NE between the first load terminal portion T2 and the second load terminal portion T4. .

  The fourth lead terminal 54 is different from the above example in that it is cut along cutting lines C1 and C2 shown in FIG. In other words, the fourth lead terminal 54 is cut along the cutting line C2, thereby removing a predetermined portion, that is, the power contact 54a as shown in FIG. 5B.

That is, the sixth lead terminal 56 is connected to the load terminal plate 31 in the one-sided switch device, and can be connected to the first load terminal plate 31A in the three-way switch device. Has been.

  According to the fourth to sixth lead terminals 54 to 56 described above, the second load terminal plate 34 is used as one terminal of both resistors R2 and R3, and the other terminal of the resistor R2 is used as one of the neon lamps NE. , The other terminal of the resistor R3 and the other terminal of the neon lamp NE can be electrically connected to the first load terminal plate 31A, respectively, and thereby the display circuit portion B shown in FIG. Will be configured.

  The switch device 1A is constituted by the above-described members, and the assembly method will be described next. Since the operation until the transformer block 4 is accommodated is as described above, the description thereof is omitted. After the transformer block 4 is housed in the body 60A, the two release buttons 33 are housed in the body 60A so that the operation portion 33a faces the outside of the body 60A from each jig insertion hole of the body 60A. The locking spring 32 is housed in the body 60 </ b> A so that the locking piece 32 a faces the pressing piece 33 b of the release button 33 and faces each insertion hole of the body 60.

  Thereafter, the power terminal plate 30 is housed in the body 60A as described above, and the pair of pressing pieces 31c, 31c of the load terminal portion 31b is opposed to the lock spring 32 with respect to the first load terminal plate 31A. At the same time, the first fixed contact 22 is placed on the support portion 20c of the middle frame 20A so that the first fixed contact 22 faces the power terminal plate 30 side, thereby being housed in the body 60A. Thereby, the terminal part T2 for 1st loads which consists of a quick connection terminal which locks the electric wire inserted from the insertion hole for 1st loads is comprised. Next, the second load terminal plate 34 is configured such that the pair of pressing pieces 31c and 31c of the load terminal portion 34b face the lock spring 32 and the second fixed contact faces the first fixed contact 22A. In this way, it is housed in the body 60A by being placed on the support portion 20e of the middle frame 20A. Thereby, the 2nd terminal part T2 for loads which consists of a quick connection terminal which locks the electric wire inserted from the 2nd insertion hole 60b for loads is comprised.

  As described above, as shown in FIG. 11, the transformer block 4, the inner frame 20A, the support plate 21, the power terminal plate 30, the first load terminal plate 31A, and the second load terminal plate 34. The four locking springs 32 and the two release buttons 33 are stored in the body 60A, and thereafter, the illumination block 5A is stored as follows. That is, the illumination block 5A is connected to the respective connected portions 58 and 59 of the illumination block 5 by inserting and connecting the tip portions 41a of the respective connection portions 41 of the transformer block 4, and the first load terminal plate 31A and the second load terminal plate 31A. The first load contact 56a and the second load contact 54e of the illumination block 5 are elastically contacted with the load terminal plate 34, and are housed in the body 60A.

  Therefore, since the illumination block 5A can be connected to the transformer block 4 by plugging connection, it is not necessary to perform soldering.

  The body 60A that houses the illumination block 5A has an opening / closing element 23A, the base end of the opening / closing element 23A is brought into contact with the flat plate portion 21a of the support plate 21, and the shaft portion 23b as a bearing portion of the body 60. The first movable contact is provided to the first fixed contact 22A in a state where the portion 23c is inserted into the bearing portion of the rib 20d of the middle frame 20 and the restriction projection 23d is inserted into the restriction groove portion of the rib 20d of the middle frame 20. Then, the second movable contact 26 is stored in a state of being opposed to the second fixed contact, and then the cover 61 is attached to the body 60A as described above.

  As a result, a switch device 1A is obtained. The switch device 1A has a first fixed contact, a second fixed contact, and a movable contact that is brought into and out of contact with each fixed contact, and the movable contact is a first fixed contact. And a switch mechanism SW2 that selectively contacts one of the second fixed contacts, a first load terminal plate 31A used as a first terminal plate electrically connected to the first fixed contact, A second load-side terminal plate 34 used as a second terminal plate electrically connected to the second fixed contact, and a power supply terminal used as a third terminal plate electrically connected to the movable contact A three-way type equipped with a plate 30. In the three-way type switch device, the connection destination of each terminal board 30, 31A, 34 varies depending on the type of use. Therefore, the power supply terminal board 30 and the load terminal boards 31A, 34 are not necessarily connected to the power supply line of the power supply AC. The load power lines are not necessarily connected to each other (for example, in the switch device 1A on the right side shown in FIG. 9, the power line of the load L is connected to the power terminal plate 30). In order to contrast with the configuration of the switch device of FIG.

  The switch device 1A is attached to an attachment frame (not shown) using attachment claws 61i and 61i, and further a piano handle (not shown) is attached swingably using a shaft portion 61f. Provided for use.

  Next, the operation of the switch device 1A will be briefly described. The switch device 1A is mainly used in two sets. As shown in FIG. 9, one end of the power source AC is connected to the terminal portion T1 of one switch device 1A (the left switch device 1A in FIG. 9). One end of the load L is connected to the other end of the power source AC, the other end of the load L is connected to the terminal portion T1 of the other switch device 1A (the right switch device 1A in FIG. 9), and both switch devices are connected. It is used in a state where the terminal portions T2 and T4 of 1A and 1A are connected to each other (that is, a state where both switch devices 1A and 1A are connected in series between the power source AC and the load L).

  In the initial state, the terminal portion T1 of one switch device 1A is connected to the terminal portion T2 (the first movable contact is in contact with the first fixed contact 22A, and the second movable contact 26 is the second The terminal portion T1 of the other switch device 1A is connected to the terminal portion T4 (the first movable contact is separated from the first fixed contact 22A and the second movable contact 26 is separated). Is in contact with the second fixed contact).

  In this initial state, as shown in FIG. 9, the terminal portion T1 of one switch device 1A, the primary winding N1 of the current transformer CT, the switch mechanism portion SW2, the display circuit portion B, the terminal portion T4, and the other switch device. A current flows in the terminal section T4 of 1A, the switch mechanism section SW2, the primary winding N1 of the current transformer CT, and the electric path of the terminal section T1, and the terminal section T1 of one switch device 1A and the primary winding of the current transformer CT N1, the switch mechanism SW2, the terminal T2, the terminal T2 of the other switch device 1A, the display circuit B, the switch mechanism SW2, the primary winding N1 of the current transformer CT, and the electric current through the terminal T1. As a result, the neon lamp NE of each switch device 1A is turned on, so that the position of each switch device 1A can be known even in the dark. Of course, when the neon lamp NE is lit, power supply to the load L is insufficient, so that the load L is not operated and the light emitting diode LED is not lit.

  When the push button handle 62 of one of the switch devices 1A is pushed from the initial state, the reversing handle 24 is swung by the slide cam. When the reversing handle 24 is swung in this way, the reversing spring 25 is at the middle of the swung range. Pass through the position to be compressed. Before and after this position, the direction of the spring force acting on the opening / closing element 23A from the reversing spring 25 is reversed. As a result of the spring force of the reversing spring 25, the switch 23A swings rapidly, and the first movable contact of the switch 23A is separated from the first fixed contact 22A of the first load terminal plate 31A. The second movable contact 26 of the switch 23A contacts the second fixed contact of the first load terminal plate 34, whereby the switch mechanism SW2 is switched, and the terminal T1 is connected to the terminal T4. Will be.

  And when switch mechanism part SW2 is switched, terminal part T1 of one switch apparatus 1A, primary winding N1 of current transformer CT, switch mechanism part SW2, terminal part T4, terminal of the other switch apparatus 1A A current flows through the electric path of the part T4, the switch mechanism part SW2, the primary winding N1 of the current transformer CT, and the terminal part T1, thereby supplying sufficient power from the power source AC to the load L, and the load L can be operated. At the same time, almost no current flows through the neon lamp NE of each switch device 1A, and the neon lamp NE is turned off. At the same time, when a sufficient current flows through the primary winding N1 of the current transformer CT of each switch device 1A, an induced electromotive force is generated in the secondary winding N2 of the current transformer CT. On the secondary winding N2 side, a current flows through the electrical path of the secondary winding N2, resistor R1, light emitting diode LED, and secondary winding N2, and the light emitting diode LED is turned on. By seeing, it is possible to visually recognize that power is being supplied to the load L.

  Thereafter, when the push button handle 62 of one switch device 1A is pressed again, the reversing handle 24 swings so as to return to the initial state, whereby the switch mechanism SW2 is switched to return to the initial state described above, and the load As the operation of L is turned off, the light emitting diode LED of each switch device 1A is turned off, and the neon lamp NE of each switch device 1A is turned on instead.

  By the way, when the push button handle 62 of the other switch device 1A is pushed from the initial state, the switch mechanism part SW2 is switched by the same operation as described above, and the terminal part T1 is connected to the terminal part T2. become. When the switch mechanism unit SW2 is switched in this way, the terminal unit T1 of one switch device 1A, the primary winding N1 of the current transformer CT, the switch mechanism unit SW2, the terminal unit T2, and the other switch device. Current flows through the terminal portion T2 of 1A, the switch mechanism portion SW2, the primary winding N1 of the current transformer CT, and the electric path of the terminal portion T1. Accordingly, as in the case where the push button handle 62 of one switch device 1A is pushed from the initial state, sufficient power is supplied from the power source AC to the load L so that the load L can be operated, and each neon lamp NE is operated. Is turned off, and the light emitting diode LED is turned on instead. Thereafter, when the push button handle 62 of the other switch device 1A is pressed again, the reversing handle 24 swings so as to return to the initial state, whereby the switch mechanism SW2 is switched to return to the initial state described above, and the load As the operation of L is turned off, the light emitting diode LED of each switch device 1A is turned off, and the neon lamp NE of each switch device 1A is turned on instead.

  As described above, the illumination block 5 cuts the fourth lead terminal 54 at a predetermined portion, so that not only the one-sided switch device having the circuit configuration shown in FIG. 2 but also the one shown in FIG. It is configured so that it can also be used for a three-way switch device having a simple circuit configuration. For this reason, the illumination block 5 can be shared by the one-sided switch device and the three-way switch device, and the initial investment cost (mold investment amount, etc.) of the illumination block 5 can be suppressed. The production cost can be reduced.

  In the illumination block 5, a fourth lead terminal 54 is provided on one end side of the illumination block 5 (upper end side in FIG. 6A). Since it is provided on the end side (the lower end side in FIG. 6B), it is easy to cut the fourth lead terminal 54, thereby cutting the fourth lead terminal 54 in the illumination block 5. Therefore, there is no need to provide a space for this, so that the illumination block 5 can be made compact.
